P0794 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0794 qhia txog qhov sib cuam tshuam / sib cuam tshuam hauv lub nruab nrab ncej ceev sensor "A" Circuit Court

Qhov txhaum cai txhais li cas P0794?

Teeb meem code P0794 qhia txog teeb meem teeb meem nyob rau hauv kev sib kis nruab nrab ncej ceev sensor "A" Circuit Court. Nws tshwm sim thaum lub kis tau tus mob tswj module (TCM) pom ib qho tsis ruaj tsis khov los yog tsis sib xws teeb liab los ntawm kev ceev sensor "A" lossis nws lub voj voog. Yog tsis muaj lub teeb liab raug los ntawm qhov sensor, qhov kis tsis tuaj yeem hloov lub zog kom zoo. Feem ntau, qhov ceev ntawm lub nruab nrab ncej yuav tsum maj mam nce mus txog rau thaum lub iav hloov. Txawm li cas los xij, yog tias lub sensor tsis ua haujlwm, cov txheej txheem no tsis tshwm sim, ua rau nws tsis tuaj yeem txiav txim siab qhov zoo tshaj plaws iav hloov lub tswv yim.

Tej zaum ua rau

Teeb meem code P0794 tuaj yeem tshwm sim los ntawm ntau yam laj thawj:

1. Qhov ceev sensor "A" nws tus kheej yog faulty.
2. Kev puas tsuaj lossis qhib rau hauv cov xov hlau lossis cov khoom sib txuas txuas nrog lub ntsuas nrawm "A" mus rau qhov kis tau tus mob tswj module (TCM).
3. Kev teeb tsa tsis raug lossis calibration ntawm ceev sensor "A".
4. Teeb meem nrog lub kis tau tus mob tswj module (TCM) los yog nws software.
