P0812 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0812 qhia tias muaj kev ua haujlwm tsis zoo nyob rau hauv qhov rov qab input circuit.

Qhov txhaum cai txhais li cas P0812?

Teeb meem code P0812 qhia tias muaj teeb meem nyob rau hauv qhov rov qab input circuit. Qhov no txhais tau hais tias tus kis tau tus mob tswj module (TCM) tau kuaj pom qhov tsis sib xws ntawm qhov rov qab lub teeb hloov lub teeb liab thiab lub kis tau tus mob selector thiab hloov chaw sensor teeb liab. Lub kis tau tus mob tswj module (TCM) siv lub teeb liab rov qab hloov teeb liab raws li ib qho ntawm nws cov lus qhia tias rov qab iav yog qhib. Lub TCM pom cov iav rov qab ua kom raws li cov teeb liab los ntawm lub teeb rov qab hloov thiab lub iav xaiv thiab hloov chaw sensors. Yog tias lub teeb liab rov qab hloov lub teeb liab tsis sib xws rau qhov kev xaiv kis tau tus mob thiab hloov chaw sensors, TCM teeb tsa DTC P0812.

Tej zaum ua rau

Qee qhov laj thawj rau P0812 teeb meem code:

• Rov qab lub teeb hloov malfunction: Yog tias lub teeb rov qab hloov tsis ua haujlwm kom raug lossis tsim cov cim tsis raug, tus lej P0812 yuav tshwm sim.
• Teeb meem nrog kev xaim lossis cov khoom sib txuas: Kev tawg, kev xeb, lossis kev puas tsuaj hauv cov xaim lossis cov khoom sib txuas txuas lub teeb rov qab mus rau qhov hloov pauv hloov pauv (TCM) tuaj yeem ua rau cov teeb liab tsis tau nyeem kom raug thiab ua rau DTC tshwm sim.
• TCM malfunction: Teeb meem ntawm kev tswj kev sib kis ntawm nws tus kheej, xws li faulty electronic Cheebtsam lossis software, kuj tuaj yeem ua rau P0812 code.
