P0238 – OBD-II Teeb meem Code Technical Description

• Hom: Turbo / Boost Sensor "A" Circuit High Input
• GM: Dodge Chrysler Turbocharger Boost Sensor Circuit Court High Voltage:
• MAP sensor voltage siab dhau lawm

Qhov teeb meem code P0238 txhais li cas?

Code P0238 yog ib tug generic kis tau tus mob diagnostic teeb meem code (DTC) uas siv rau cov tsheb nrog ib tug turbocharger xws li VW, Dodge, Mercedes, Isuzu, Chrysler, Jeep thiab lwm yam. Lub powertrain tswj module (PCM) siv lub zog tswj solenoid los tswj lub siab tsim los ntawm lub turbocharger. Lub turbocharger boost siab sensor muab cov ntaub ntawv siab rau PCM. Thaum lub siab tshaj 4 V thiab tsis muaj kev txhawb nqa, tus lej P0238 tau nkag.

Lub boost siab sensor teb rau cov kev hloov nyob rau hauv intake manifold siab generated los ntawm lub turbocharger thiab nyob ntawm seb lub accelerator thiab cav ceev. Lub cav tswj module (ECM) siv cov ntaub ntawv no los kuaj xyuas thiab tiv thaiv lub cav. Lub sensor muaj 5V siv Circuit Court, hauv av Circuit Court, thiab lub teeb liab Circuit Court. Lub ECM muab 5V rau lub sensor thiab ua rau hauv av Circuit Court. Lub sensor xa cov teeb liab mus rau ECM, uas saib xyuas nws rau qhov txawv txav.

P0238 code tau tshwm sim thaum ECM pom tias lub teeb liab los ntawm lub zog siab sensor yog qhov txawv txav, qhia txog qhov qhib hluav taws xob lossis hluav taws xob siab.

P0229 kuj yog ib qho OBD-II code uas qhia tias muaj teeb meem nyob rau hauv lub throttle/pedal txoj hauj lwm sensor Circuit Court uas ua rau ib tug intermittent input teeb liab.

Cov tsos mob ntawm tus lej P0238 tuaj yeem suav nrog:

Yog tias muaj tus lej P0238 tam sim no, PCM yuav qhib lub tshuab kuaj xyuas lub teeb thiab txwv qhov kev txhawb zog siab, uas yuav ua rau muaj mob hauv tsev. Hom no yog tus cwj pwm los ntawm kev poob lub zog loj thiab kev nrawm nrawm. Nws yog ib qho tseem ceeb los kho qhov ua rau ntawm qhov teeb meem no sai li sai tau, vim nws tuaj yeem ua rau lub catalytic converter puas.

Cov tsos mob rau tus lej P0238:

1. Lub teeb Check Engine yog qhib.
2. Txwv lub cav fais fab thaum lub sij hawm acceleration.
3. Lub Cheeb Tsam Lub Teeb thiab Throttle Control (ETC) lub teeb tau qhib.
4. Ntau yam kev tsis txaus siab tuaj yeem ua tau, nyob ntawm qhov chaw tsim khoom.

Cov tsos mob ntxiv rau cov teeb meem throttle valve:

1. Ua kom tiav throttle kaw thaum nres kom tsis txhob over-revving.
2. Kho lub throttle valve thaum lub sij hawm acceleration kom txwv tsis pub qhib.
3. So tsis txaus los yog tsis ruaj tsis khov thaum braking vim yog kaw throttle.
4. Tsis zoo los yog tsis muaj lus teb thaum lub sij hawm acceleration, txwv tsis pub muaj peev xwm ua kom nrawm.
5. Txwv tsheb ceev kom 32 mph lossis qis dua.
6. Cov tsos mob yuav ploj mus thaum lub tsheb rov pib dua, tab sis lub teeb pom kev ntawm Lub Cav yuav nyob twj ywm kom txog thaum kho lossis cov lej raug tshem tawm.

Tej zaum ua rau

Yog vim li cas rau kev teeb tsa tus lej P0299 yuav suav nrog cov hauv qab no:

1. DTCs muaj feem xyuam rau Intake Air Temperature (IAT) sensor, Cav Coolant Temperature (ECT) sensor, los yog 5V siv.
2. Qee zaum teeb meem thaiv kab mob.
3. Faulty boost sensor "A".
4. Short rau voltage nyob rau hauv lub sensor Circuit Court.
5. Faulty PCM (lub cav tswj module).
6. Lub boost siab sensor hlua yog qhib los yog luv.
7. Ua kom cov hluav taws xob sib txuas ntawm lub siab sensor Circuit Court.
8. Lub boost siab sensor yog faulty.
9. Faulty turbo/supercharger ntaus ntawv.
10. Lub cav tau overheated.
11. Misfire tshaj calibrated pib.
12. Lub khob sensor (KS) faulty.
13. Qhib Circuit Court ntawm lub turbocharger siab sensor nrog qhov nce hauv.
14. Lub turbocharger siab connector A puas lawm, ua rau lub Circuit Court qhib.
15. Boost siab sensor. Cov hlua hluav taws xob luv luv ntawm lub sensor thiab lub cav tswj module (ECM).

P0238 Cov ntaub ntawv tshwj xeeb

1. 0238 - CHRYSLER MAP boost sensor voltage siab.
2. P0238 - High voltage nyob rau hauv ISUZU turbocharger boost sensor Circuit Court.
3. P0238 - Siab teeb liab theem nyob rau hauv lub turbocharger / boost sensor Circuit Court "A" MERCEDES-BENZ.
4. P0238 - Siab teeb liab theem nyob rau hauv lub boost sensor Circuit Court "A" VOLKSWAGEN Turbo / Super Charger.
5. P0238 - VOLVO boost siab sensor teeb liab siab dhau.

Yuav kuaj li cas P0238?

Nov yog cov ntawv sau rov qab:

1. Luam theej duab cov lis dej num thiab teev cov ntaub ntawv khov nab kuab los txheeb xyuas qhov teeb meem.
2. Clears cov lis dej num kom pom tias qhov teeb meem rov qab los.
3. Tshawb xyuas lub zog siab sensor teeb liab thiab muab piv nrog lub cav tsis ua haujlwm ceev sensor teeb liab kom ntseeg tau tias kev nyeem ntawv sib tw.
4. Tshawb xyuas lub turbocharger sensor thaiv kab thiab txuas rau cov cim qhia ntawm luv luv hauv cov xov hlau.
5. Xyuas lub turbocharger sensor connector rau corroded hu uas yuav ua rau ib tug luv luv nyob rau hauv lub teeb liab Circuit Court.
6. Sib piv cov ntawv nyeem rau cov lus qhia tshwj xeeb thaum txheeb xyuas cov ntaub ntawv sensor.

Kev kho dab tsi tuaj yeem kho qhov teeb meem P0238?

Nov yog cov ntawv sau rov qab:

1. Kho lossis hloov cov kab hluav taws xob sensor thiab kev sib txuas raws li qhov tsim nyog.
2. Hloov lub faulty throttle control unit vim muaj qhov tsis xws luag.
3. Hloov lossis reprogram ECM yog tias pom zoo tom qab ua qhov kev sim xaiv thiab xyuas kom meej tias tsis muaj lwm yam cuam tshuam nrog lub sensor lossis thaiv.

P0238 Cav Code yog dab tsi [Quick Guide]

Code P0229 yog tshwm sim los ntawm erratic lossis intermittent signals los ntawm lub sensor mus rau ECM. Cov teeb liab no tseem nyob hauv thaj tsam ntawm lub sensor thaum lub teeb liab tau txais los ntawm ECM.
