APP sensor (Accelerator Pedal Position Sensor)

Accelator Position Sensor, au ‘sensa’ ya kanyagio cha kuongeza kasi ya gari, namna jina ilivyo, inapeleka umbea kuhusu kiwango dereva amakanyaga ki kanyagio, kwenda kwenye kompyuta ya gari! Sasa, kulingana na habari hii, kompyuta itajua niaje kuhusu kiasi cha mafuta cha mafuta uachiliwa kuchomwa, obviously na kiasi gani cha hewa ile throttle iwachilie!
Sensoryenyewe ipo hapo, juu ya kanyagio!

Moduli ya kanyagio inaweza kuundwa kwa uchawi wa, potentiometer au wa Magnetic Hall Effect, kulingana, au namna hii video itakuonesha ndani zaidi! Namna yeyote, lakini Sensor hii inasajili fasta fasta harakati na msimamo wa kanyagio cha kuongeza kasi.


May be ukitaka ‘kulewa’ zaidi sana kuhusu huo uchawi wa Magnetic Hall Effect, bonyeza tu HAPA au kwenye hii picha chini!

Jinsi umeelewa, au kukumbuka, hii sensor inapeleka umbea kwenye kompyuta ya gari, alafu kompyuta inamuambia Throtle kiasi ya kufunguka, obviously na blaa bla zingine kwenye CAN, kiasi cha mafuta kinachohitajika, kulingana…
Na sababu kwanini zinakuanga sensor mbili ndani ya moja, au?

Sawa, jinsi tumejua kompyuta au ECU inatuma umeme 5V kuzungukia kwenye kila moja ya hizi sensor nani ya APP sensor, na juu ya huo uchawi w
a Hall Effect au Variable Resistance, kulingana kiasi ya mzunguko ata resistance itabadilika!
Sasa, wakati unapima, ukiona waya 6, lazima upate 5V mbili, ground au negative mbili, na siginal ….mbi?

 

MAP sensor

MAP sensor, au, Manifold Absolute Pressure Sensor, inapima kiasi au uzito wa mkusanyiko wa hewa uliopo kwenye ‘intake manifold’!
Mkusanyo wa hewa ukijumulisha na hewa inaotoka njia za mfumo zingine kama, EGR, TURBO, PCV, nk!Manifold ni hicho ki bla blaa kabla hewa kuingia cylinder au baada ya Throttle

Hii sensor inaeza kuwekwa popote, kulingana gari, ili mradi kuna njia yakufikia kupima hiyo hewa!


Ukitaka maelekezo mengine ya ndani ndani, namna inavyofanya kazi wapi vipi, nk, unaeza kutazama hii video


May be ukitaka kuelewa zaidi kuhusu huo uchawi wa Piezo ambao Pressure sensor nyingi zinategemea, bonyeza HAPA kwenye hii link au picha hapa chine LINK


Sensor hiyo mara nyingi inaka namna hii

Jinsi yalivyoelezwa yote kwenye hizo video, sensor hii inaweza kuwa na waya tatu au waya nne.

Mara nyingi reference voltage inakuwaga 5V kutoka kwenye ECU!

Weka igntion-ON, chunguza umeme kwenye hizo waya!

CONTROL SYSTEMS (intro)

Siku hizi almost kila kitu kinaundwa kuwa na hii blaa bla ya CONTROL SYSTEMS, mfano, AC za ofisini, nyumbani mataa yanajiwasha yenyewe, gari za siku hizi kila kitu mafundi wanazungumza ‘kontulo’ yaani control (ECU) ama kompyuta ya gari, nk!

Hapa tunaelezana kwa ufupi, maana na jinsi, au namna huu uchawi wa CONTROL SYSTEM unakuwa!

Imagine huu mfumo wa hesabu

X + 5 = Y

(5 haibadiriki, lakini X au na Y inaeza kuwa chechote)!
X ikiwa 2, ina maana Y itakuwa 7
2 + 5 = 7
Ina maana ukitaka mfumo wako uwe tu wenye 7 kama matokeo, lazima X uingize iwe 2, au na vinginevyo! Ukitaka matokeo au Y iwe 9, hapo lazima X iongezeke kuwa 4!

Tayari, hapa 5 ni control!
Huo mfumo 5 (control) kudhibiti matokeo kwenye Y(output) kulingana X (input) itakachokuwa, ni CONTROL SYSTEM wa X + 5 = Y

CONTROL SYSTEM ni mfumo ambao matokeo yanategemea maingizo!Kwa mfano wetu pale juu,
Input  ni X, Control ni 5, alafu Output ni Y!

Alafu hizi CONTROL SYSTEMS zinaundwa kwa aina au namna mbili! Kuna zile ambao hamna aja ya kuthibitisha au ku comfirm matokeo, a.k.a OPEN LOOP CONTROL SYSTEMS, alafu na zile ambao lazima, au ata matokeo yanafanya uchawi ata kwenye mainginzo, ambao ni CLOSED LOOP CONTROL SYSTEM!

Naomba, ili kueleezana viruzi tofauti kati ya hizi aina, kutumisa mfano wa ile AC ya kudhibiti ujoto chumbani au ata ikiwa gari!

OPEN LOOP CONTROL SYSTEM

Imagine, hiyo siginal ya INPUT inatokea kwenye Temperature sensor inaochunguza ujoto chumbani au ata kwenye gari, mfumo ni kwamba hiyo Temperature sensor ikipeleka umbea kwamba kuna ujoto chumbani, hapo AC itaanza, yaani itawaka tu, hata kama hakuna mtu yeyote chumbani! Sasa ndo hizi OPEN LOOP CONTROL SYSTEM!

CLOSED LOOP CONTROL SYSTEM

Sasa hiyo siginal ya INPUT inatokea kwenye Temperature sensor imeruhusu AC kuanza, lakini AC ikiwaka lazima kuna ijulishe au ipeleke umbea kwamba nimewaka! Sasa huko sehemu ndo kuna blaa blla zingine kuchunguza kama kuna watu au la, ikiwa la AC itajizima yenyewe! Huo mzunguko ndo CLOSED LOOP CONTROL SYSTEM!

Kukitokea mfano tatizo, tuseme huku AC inawaka hata bila watu au vinginevyo, ukifanya diagnosis hizo blaa blaa za OPEN LOOP detected!

Bosch Automotive Electrics and Automotive Electronics(PDF)

Of late, the development of the motor vehicle has been marked by the introduction of electronics.
At first, electronic systems were used to control the engine (electronic fuel-injection systems), then electronic components entered the domain of driving safety (e.g. antilock brake system, ABS).
More recently, completely new fields of application have emerged in the areas of driving assistance, infotainment and communication as a result of continuous advancements in semiconductor technology.
Consequently, the proportion of electrics and electronics in the motor vehicle has continuously increased.

The complexity of the vehicle system is set to increase still further in the near future. To guarantee operational reliability in view of this complexity, new methods of electronics development are called
for. The objective is to create a standardized architecture for the electrical system/electronics that alsooffers short development times in addition to high reliability for the electronic systems.

This writing or technical manual equips you with a powerful tool of reference for information about the level of today’s technology in the
field of vehicle electrical systems and electronics. Many topics are addressed in detail, while others –particularly the electronic systems – are only presented in overview form. These topics receive in-depth
coverage in other books in our series.

ujanja wa Virtual Private Server (VPS)

A Virtual Private Server (VPS) uses virtualization software to partition physical servers into multiple “virtual” servers—each having the ability to run its own operating system and applications. VPS is not for everyone, but is quickly becoming the hosting preference of choice for advanced Web developers who require root access to the server to run their own software.

Uchawi wa PIEZOELECTRIC EFFECT

Huu uchawi wa PIZOELECTRIC EFFECT ni kwamba, ukigonga au kukandamiza kitu kiliotengenezwa kwa ile kemikali ya crystal blaa blaa😂🤣😁, hicho kitu kinaweza kuzaa umeme. TENA ukipitisha umeme katika hicho kitu, kitatemeka (to vibrate/shake or move)! So ni vice versa namna tulijaribu kuoneshana kwenye hii video🤷🏼‍♂️

AUTOMOTIVE ELECTRONICS (sensors, actuators, ECU,etc)

Kwa kutaka kuongeza nguvu za magari, bila kutumisa mafuta mengi, pamoja na bila kuharibu mazingira🤔, wataalamu waligundua namna ya kuchunguza mafuta na hewa inaoingia kwenye engine…pamoja na kuchunguza huo moshi unaotoka kwa engine🙄 ili husiharibu mazingira nje ya gari. So waliweka sensor za kuchunguza na kupeleka umbea kwenye ECU/control box (computer), alafu ndo computer iwaambie actuators kazi ya kufanya, kulingana🤷🏼‍♂️!
Sasa, kwasababu engine ya gari inategemea mafuta na hewa ili kuweza kufanya kazi, ndo maana njia za mafuta na hewa pamoja na hewa chafu (moshi) waliweka hizo sensor na actutors! So we shall look at all the sensors on in each systems as ellaborated in this video


AIRFLOW METER SENSOR

Either hii sensor inapima tu ujoto, AU inapima ujoto pamoja na uzito wa hewa inaoingia ndo hapo inaitwa Mass Airflow meter sensor!

Ikiwa inapima tu ujoto inakuwa na wire 2 tu

Iiwa inapima ujoto na uzito wa hewa, inaweza kuwa na🤔,
> 5 wires (2 yakupima joto, 3 za kupima uzito)
>4 wires (ground au negative wire ya upande wa kupima joto iko pamoja na ya upande wa kupima uzito)
>3 wires hakuna upande wakupima ujoto, inapima tu uzito wa hewa!

Hii video tuloneshana namna sensor inafanya kazi, pamoja na kupimwa ikiwa natatizo👩🏼‍🔧


MANIFOLD ABSOLUTE PRESSURE SENSOR (MAP)

Hewa ikifika kwenye inlet manifold itakutana hewa ingine inaotokea njia zingine kama Turbo, EGR, EVAP system, nk! Ina maana lazima au bora kuwepo namna ya kupima jumla ya hewa iliopo kwenye manifold kabla kuingia kwenye engine🤔 hapo ECU ama control ijue kiasi cha mafuta itafanya injector zitoe😎! So, hii MANIFOLD PRESSURE SENSOR ndo inapima jumla ya hewa iliopo kwenye inlet manifold!
Hii sensor mara nyigi ni 3 wires🤔,
moja ni 12V au 5V, ingine ni Negative/ground, Ingine ni ya SignalHii sensor ilitengenezwa kwa uchwa wa PIEZOELECTRIC EFFECT, ukibonyeza hapa tulijaribu kuonesha maana ya huu uchawi

Otherwise nama hii sensor inafanya kazi na kupimwa ili kujua kama ina tatizo, tulijaribu kuineshana katika hii video


ACCELERATOR PEDAL POSITION SENSOR

Sii ujajua hizi gari za kisasa kile ki pedal ni cha umeme⚡ tofauti kwa zile gari za zamani kulikuanga ka metal fulani🙄Sasa hii sensor ina sensor mbili kwa moja, because the other ni ya emegency kama upande moja ukiharibika, namna ya ufanyaji kazi na kupimwa in this video👇

#ACCELERATORPEDALSENSOR  #DRIVEbyWIRE  #5021tips


ELECTRONIC THROTTLE CONTROL

Baada ya kuganyaga kwenye accelerator pedal umbea unapelekwa kwa ECU (control box) ili ijue namna ya kunfungua hiki ki blaa blaa THROTTLE cha kuruhusu hewa ingie kwenye Engine! Hii ELECTRONIC THROTTLE CONTROL iko na kile kiko ka ulimi ya mtu hiivi kufungua na kufunga🤷🏼‍♂️! Kuna mota (motor) ya kutembeza hiki ki ulimi!  Na kuna sensor ya kuchunguza hiki ki ulimi kimefunguka kiasi gani🤔!
Namna ya kupima AND ufanji kazi tazama hii video😎

#THROTTLEbody #ENGINEsensors #5021tips


FUEL TANK-COVER SENSOR

Bila kufunga mfuniko wa kwenye tenki la mafuta, inasababisha upepo wa nje kuingia au ata mafuta kupotea kwa nja ya upepo (Evaporation)🙄! Sasa, ili kuhakisha unafunga mfuniko wa tenki, kuna sensa iliwekwa ili kwamba usipofunga, kuna taa itaonesha kwenye instrument cluster au ata taa ya check-engine yenyewe…au kuna uchawi ECU inafanya kwenye gari ili isitembee vizuri mpaka ufunge huu mfuniko😎!

#fueltankcover #automotivesensors #5021tips


FUEL TANK PRESSURE SENSOR

Jinsi unavyojua🙄, ukiweka kitu chochote kilivyo kama maji (liquid substance) kwenye kama dumu hivi, ukichezesha (shake) hiyo dumu, kuna pressure inatokea! Sasa, ata maafuta kwenye tenki la gari, kila gari ikitembea obviously inacheza so yale mafuta kuna uchawi unatokea kuyafanya kubadilika kuwa ya upepo na kuongeza pressure kwenye tenki, ndo maana kuna FUEL TANK PRESSURE SENSOR yakuchunguza kiasi cha pressure kwenye tenki😎!

Hii sensor ilitengenezwa kwa uchwa wa PIEZOELECTRIC EFFECT, ukibonyeza hapa tulijaribu kuonesha maana ya huu uchawi, so na maana ina 3wires🤷🏼‍♂️

Wakati gari inatembea, inachezesa tenki na kufanya yale mafuta (kama maji) kubadilika au ku evaporate kuwa upepo🤔! Sasa, hii EVAP SYSTEM inaosaidia kufanya uchawi ili yale mafuta ya upepo yasichanganyike au yasiende kwenye njia ya mafuta ya maji! Hii EVAP SYSTEM iko na njia mbadala yakupitisha upepo kwenda kwenye manifold au nje ya gari kulingana😨!

Kuna ile meter ya kuchunguza kiasi cha mafuta kwenye tenki (tank), kuna pump, kuna ka sieve ka kusfisha hayo mafuta, na🤔….jinsi tuanelekezana kwa hii video👇!


FUEL PRESSURE REGULATOR


 IDLE AIR CONTROL SYSTEM

Ukitoa mugu kwenye accelerator pedal (ile yakuongeza nguvu ya gari) ata ule mfuniko wa kuruhusu hewa ingie kwa engine unaziba🤐 ina maana engine ikikosa hewa itazimika🤷🏼‍♂️! Sasa uchawi wa IAC valve ni kufungua ka njia fulani ile hewa ipite kufika kwa engine ata ukitoa muugu👌 au tuseme ukitoka kwa gari inaendelea kuaka!

 

#IACvalve #ENGINEsensors #5021tips


CRANKSHAFT  & CAMSHAFT POSITION SENSORS

Assuming kwamba unajua crankshaft au camshaft ni nini, sasa ili kuweza kujua muda gani wakati cylinder fulani inafanya kitu gani na inahitaji nini, hizi CAMSHAFT na CRANKSHAFT POSITION SENSOR kuna uchawi unaziwezesha kujua ipi niaje, na kupleka huu umbea kwenye computer ya gari namna tulijaribu kumbushana au kuoneshana🍻

#crankshaftpositionsensor #camshaftpositionsensor #5021tips


ENGINE COOLANT TEMPERATURE SENSOR

Jinsi unavyojua, kifaa chenye uwezo kutembeza umeme kinabadilika kulingana ujoto au ubaridi🤔! So computer ya gari inatuma umeme kuzunguka kwenye hii ENGINE COOLANT TEMPERATURE SENSOR , kuligana ujoto/ubaridi umeme (volts) zitazorudi kwa computer, either itapungua au kubaki niaje namana tulioneshana👨‍🔧


AUTO TRANSMISSION tech & DIAGNOSIS outlines

Kwenye AUTO TRANSMISSION, uchawi zaidi zaidi ni wa valve ambao valve zinategemea solenoid, zingine ni pressure sensor na temperature sensor! SO, kama ulihelewa vizuri kuhusu blaa blaa za hizi sensor kwenye system zingine, then ili muradi picha inakuonesha hii sensor iko wapi, then troubleshooting AUTOMATIC TRANSMISSION troubles ni kama kunywa maji🍻!

#VALVEBODY #AUTOMATICTRANSMISSION #5021tips


TROUBLESHOOTING CONTROL SYSTEMS

Uchawi kuweza blaa blaa ya ma sensor, control boxi, sijui actuators ni kujua mfano ni sensor gani, iko wapi, inafanya kazi gani, inafanyaje hiyo kazi as in iliundwaje (how it is made), nk! So ukipata umbea huu wote ndo utajua inahitaji kupeleka au kutoa umeme gani kutoka wapi au blaa blaa as we explained in here👨🏼‍🎓 !

#electricalcontrolsystems #automotivesensors #5021tips

Misingi ya CAR KEY PROGRAMMING

Kwa kutaka kuzuia wizi, walifanya uchawi kwenye gari kwamba isipo kuwa funguo maalum ya hiyo gari maalum, hiyo gari haiwezi kuendeshwa. Kwenye funguo waliweka kadude fulani kanaitwa Transponder
Sasa haka kadude namna tulivyoneshana kwa video, kuna neno siri ama PIN a.k.a password ambao lazima ifanane na ilyo kwenye gari. Isipo fanana gari haitawaka!

So, kwa hii video tulijaribu kuoneshana namna hiizi blaa blaa zote zinafanya kazi

Ina maana hiyo funguo maalum ya kuendesha gari maalum ikipotea lazima ufanye uchawi wa ziada kuirudisha namna tuliojaribu kumbushana katika hii video!

ONYO🚨: Mara kwa mara kuna ujanja unaotokea wa nmna ya kufanya key programming, so hii ni just basics of what could be done in case🤷‍♂️!


Na hata kama hizo transponder zinafanana kwa muonekano, lakini ziko tofauti kaaabisa! Yaani ziko na namba mf., ID46, 4C, TPX7, nk kulingana aina ya gari! Ina maana ukileta tranponder ya Toyota Corona kuiweka kwa system ya Toyota Carina, hazitafanya🤷🏼‍♂️ namna tulioneshana kwenye hii video

Sasa kuna system zenye funguo za transpoder kama tumeone, na kuna smart key systems


Sasa, hizo smart zinabaki mfukoni kwamba unaeza kufungua mlango na kuendesha gari bila kuigusa hiyo funguo!

KEYLESS ama SAMRT KEY SYSTEM ina upande miwili, upande wa kuasha gari KEYLESS IGINITON SYSTEM, na upande mwingine wa tuseme kifahari hiiivi, KEYLESS ENTRY SYSTEM ile yakufungua mlango, booti, kutembeza viti, nk!

So namna hii video inakuonesha tutangaliza hizo part tofauti tofauti

Sasa tukianza na KEYLESS IGINTION SYSTEM tutaona namna SMART ECU ikishirikiana na ID CODE BOX, BODY ECU, ENGINE ECU, nk, ili kuwezesha engine kuaka kwa kutambua kama ndo funguo sahihi ilioko mfukoni ya huyo mtu anaejaribu kuendesha hiyo gari! Hii video ni ndeeefu pamoja na maneno mengi ya kurudia rudia ili uweze kuipata vizuri!

Sasa hapa tunajaribu kuoneshana KEYLESS ENTRY SYSTEM, utaona kwamba hapa ni SMART ECU na BODY ECU na componet zingine zinazohusiana…pamoja na uchawi gani unaweza kufanya kukitokea blaa blaa yeyote kwenye hii system!

Unajua kuna mashine nyigi na ni rahisi kutengeneza au kuongeza funguo ya smart. LAKINI ukikosea kidogo tu, ni hatari na kwamba system nzima utakuwa umehiharibu🤷‍♂️! So be careful when diagnosising for problems or when using diagnosis machine as we tried ellaborate in this video


Hapo chini, kwendelea na IMMO OFF na sijui IMMOBILIZER DECODING🙄, na vingine!
Sasa pia kuna ujanja unawefanya kwenye gari ili iwake na funguo yeyote kama kawaida au kama zamani. Kuna hiyo blaa blaa ya IMMO OFF! Namna tulioneshana kwenye hii video, kufanya IMMO OFF either unaweka emulator au ku edit data za IC ama chip ya funguo!


Tena tulijua kwamba funguo ikipotea unaweza kupata code/passsword kutoka hiyo EEPROM ili ukatumbukize kwenye funguo ingine ndo gari iwake, au pia kama control boxi imekufa unatoa haka EEPROM ukaweke kwa hiyo control boxi ingine👌! Sasa uchawi ni kusipojua EEPROM ipi ya funguo maana iwe control boxi au immo box kuna EEPROM nyingi nyingi. So hii software inakusadia kujua EEPROM ipi au Transpoder ipi inaendana hiyo gari🤔BONYEZA HAPA UWEZE KU DOWNLOAD HII SOFTWARE


Sasa tayari umejua ni EEPROM gani ya funguo🙄, je unajua nini chakufanya uweze kupata code/password ya funguo kutoka hiyo EEPROM?
So ukibonyeza HAPA utona tulikumbushana au kuoneshana kuhusu data inakuanga humu, inakaje? unahisomaje? Unahielewaje?🤷🏼‍♂️ hizo blaa blaa binary, HEX, address, nk!


Hiki kitabu kina namna ya ku program funguo za gari, mashine gani yakutumia, vifa gani vya kufungua/kufunga kwenye gari, nk! Yaani unapata almost kila umbea mhimu👌!  BONYEZA HAPA ku download🍻  😁🤣😂


Tuseme umepata idea ya namna funguo zinafanya👌! Na funguo ikipotea umejua kwamba unaweza kutumia data ya EEPROM kuweza kutenegeza ufunguo mwingine AU ukatoa tu immo system ili gari ikubali funguo yeyote. Sasa changamoto ni kujua uchawi gani wa kufanya immo off au ku program funguo ingine kwa kutumia data ya EEPROM ndo maana ukitaka niaje….bonyeza tu HAPA HAPA HAPA🤷‍♂️
