Yog tias pom muaj teeb meem, cov khoom siv cuam tshuam yuav tsum tau hloov thiab PCM / TCM units tau programmed rau koj lub tsheb. Yog tias tsis ntseeg, nws yog qhov zoo dua los tiv tauj ib tus kws kho mob uas tsim nyog rau kev kuaj mob.

Kev kuaj mob yuam kev

Thaum kuaj pom tus lej P0840, qhov yuam kev feem ntau yuav suav nrog:

1. Kev tshuaj xyuas tsis txaus ntawm cov ntawv xov xwm kev pabcuam (TSBs) kom paub txog cov teeb meem thiab kev txhim kho ntsig txog cov cai no.
2. Kev soj ntsuam tsis tiav lossis tsis zoo ntawm cov xaim thiab cov khoom sib txuas ua rau lub tshuab xa hluav taws xob siab sensor (TFPS).
3. Kev txhais lus tsis zoo ntawm cov txiaj ntsig kev kuaj mob, tshwj xeeb tshaj yog hais txog cov chaw tsim khoom tshwj xeeb rau kev tiv thaiv thiab qhov hluav taws xob.
4. Tsis tuaj yeem kuaj xyuas cov teeb meem hauv kev sib kis xws li cov dej xau, lub siab txhaws lossis teeb meem ntawm lub cev valve.
5. Kev tsis saib xyuas qhov kev pab cuam kom raug lossis calibrate PCM/TCM tom qab hloov cov khoom.

Muab qhov nyuaj ntawm kev kuaj xyuas qhov teeb meem no, nws raug nquahu kom koj hu rau tus kws tshaj lij lossis lub khw kho tsheb kom raug thiab kho tau zoo.

Txoj cai txhaum loj npaum li cas? P0840?

Teeb meem code P0840 qhia txog ib qho teeb meem hauv kev tswj kev sib kis uas cuam tshuam nrog kev sib kis ntawm cov kua dej siab sensor / hloov. Nyob ntawm seb qhov laj thawj tshwj xeeb thiab cov xwm txheej ntawm kev siv lub tsheb, qhov hnyav ntawm txoj cai no yuav txawv. Qee qhov tshwm sim tuaj yeem suav nrog kev hloov pauv hloov pauv hloov pauv, siv roj ntau ntxiv, lossis lwm yam teeb meem sib kis.

Nws yog ib qho tseem ceeb uas yuav tsum tau xyuam xim rau cov tsos mob thiab pib kuaj mob thiab kho tam sim ntawd kom tsis txhob muaj teeb meem loj zuj zus tuaj thiab ua rau muaj kev puas tsuaj rau kev sib kis.
