P0509 Idle Cua Tswj Valve Circuit Court High

P0509 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0509 qhia tias PCM tau kuaj pom qhov hluav taws xob siab nyob rau hauv qhov tsis muaj cua valve tswj qhov system.

Qhov txhaum cai txhais li cas P0509?

Teeb meem code P0509 qhia tias muaj teeb meem nrog lub cav tsis ua haujlwm ceev. Txhua lub tsheb muaj qhov tshwj xeeb idle speed range. Lub tsheb PCM tswj qhov tsis siv neeg ceev. Yog tias PCM pom tias lub cav tsis ua haujlwm siab dhau lawm, nws yuav sim kho lub cav RPM. Yog tias qhov no ua tsis tiav, qhov yuam kev code P0509 yuav tshwm sim thiab lub teeb pom kev pom lub cav yuav teeb.

Tej zaum ua rau

Teeb meem code P0509 tuaj yeem tshwm sim los ntawm cov laj thawj hauv qab no:

• Tsis muaj teeb meem huab cua ceev sensor (IAC) lossis xaim.
• Kev ua haujlwm tsis raug ntawm tus tswj ceev ceev.
• Teeb meem nrog huab cua ntws los yog lub tshuab nqus tsev vacuum cuam tshuam rau kev khiav haujlwm ceev tswj.
• Cav tswj module (ECM/PCM) malfunction.
• Fais fab lossis av teeb meem hauv lub cav tswj qhov system.
• Qhov tsis xws luag hauv cov roj txhaj tshuaj lossis cov lim lim.
• Malfunction ntawm lub ignition distributor sensor los yog ignition system.
• Teeb meem nrog lub throttle mechanism.

Cov no tsuas yog qee qhov ua tau, thiab kev kuaj mob kom raug yuav tsum tau kuaj xyuas cov khoom siv thiab cov tshuab ntawm lub tsheb.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0509?

Cov tsos mob rau DTC P0509 yuav suav nrog cov hauv qab no:
