P0253 Tsawg teeb liab theem nyob rau hauv kev tswj Circuit Court ntawm roj metering twj "A" (cam/rotor/injector)

P0253 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0253 qhia tias cov roj ntsuas twj tso kua mis "A" tswj Circuit Court (cam/rotor/injector) tsawg dhau.

Qhov txhaum cai txhais li cas P0253?

Teeb meem code P0253 qhia txog teeb meem nrog kev tswj hwm roj ntawm cov cav diesel. Nws qhia tau hais tias lub cav tswj module (PCM) tau kuaj pom qhov tsis sib xws ntawm qhov hluav taws xob hluav taws xob xa mus rau hluav taws xob tswj hluav taws xob thiab lub teeb liab hluav taws xob rov qab los ntawm chav ntsuas roj. Qhov no tej zaum yuav yog vim tsis txaus los yog ntau dhau roj siab tau muab nkag rau hauv cov roj system.

Tej zaum ua rau

Teeb meem code P0253 tuaj yeem tshwm sim los ntawm ntau yam laj thawj:

• Malfunction ntawm hluav taws xob tswj tsav tsav: Teeb meem ntawm lub tshuab hluav taws xob nws tus kheej, uas tswj cov khoom siv roj, tuaj yeem ua rau cov cai no tshwm sim.
• Teeb meem nrog cov roj dispenser: Kev ua txhaum cai hauv chav ntsuas roj, uas yog lub luag haujlwm rau kev faib cov roj kom raug, tuaj yeem ua rau P0253 code tshwm.
• Tsis yog qhov voltage los yog tsis kam nyob rau hauv hluav taws xob Circuit Court: Teeb meem ntawm kev xaim, cov khoom sib txuas, lossis kev sib txuas ntawm lub tshuab hluav taws xob tswj hluav taws xob thiab PCM tuaj yeem ua rau muaj teeb meem tsis sib xws thiab ua rau qhov yuam kev no tshwm sim.
• Teeb meem nrog roj siab sensors lossis sensors: Kev ua haujlwm tsis zoo hauv cov sensors lub luag haujlwm rau kev ntsuas cov roj siab hauv lub cev tuaj yeem ua rau kev ua haujlwm tsis raug ntawm cov roj tswj qhov system.
• Teeb meem nrog PCM lossis lwm yam khoom siv hluav taws xob: Kev ua txhaum ntawm PCM nws tus kheej lossis lwm yam khoom siv hluav taws xob cuam tshuam nrog lub cav tswj kev tswj hwm kuj tuaj yeem ua rau P0253 code tshwm.

Cov no tsuas yog qee qhov ua tau, thiab txhawm rau txiav txim siab qhov laj thawj kom raug, nws yog qhov yuav tsum tau ua kom paub meej txog kev kuaj mob ntawm lub tsheb siv cov cuab yeej tshwj xeeb.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0253?

Cov tsos mob uas yuav tshwm sim thaum DTC P0253 tuaj yeem muaj xws li hauv qab no:

• Poob lub cav fais fab: Tej zaum yuav poob lub zog thaum nrawm lossis thaum tsav tsheb.
• Kev ua haujlwm tsis ruaj khov ntawm lub cav: Lub cav yuav muaj kev ntxhib los mos, tshee, tshee, lossis ntxhib idling.
• Teeb meem pib lub cav: Yog tias muaj qhov tsis sib xws ntawm cov khoom siv roj, nws yuav nyuaj rau pib lub cav, tshwj xeeb tshaj yog thaum pib txias.
• Deteriorating roj kev lag luam: A P0253 code yuav ua rau kev lag luam roj tsis zoo vim tias kev tswj hwm roj tsis ua haujlwm raug.
