P0819 Iav ntau qhov nce thiab nqis ua haujlwm sib cuam tshuam

P0819 – OBD-II Teeb meem Code Technical Description

DTC P0819 qhia txog kev ua txhaum ntawm kev sib hloov ntawm kev sib hloov thiab downshift.

Qhov txhaum cai txhais li cas P0819?

Teeb meem code P0819 qhia tias lub iav ntau tsis sib haum thaum hloov mus thiab nqis. Qhov no txhais tau hais tias lub powertrain control module (PCM) tau kuaj pom qhov tsis sib xws ntawm qhov qhia thiab cov iav qhov tseeb thaum lub sijhawm ua haujlwm. Qhov kev ua yuam kev no tsuas yog tshwm sim ntawm cov tsheb uas tsis siv neeg kis. Yog tias PCM pom qhov tsis sib xws ntawm qhov qhia thiab cov iav qhov tseeb, lossis yog tias qhov hluav taws xob hluav taws xob tawm ntawm qhov ntau, tus lej P0819 yuav raug teeb tsa thiab teeb pom kev tsis zoo (MIL) tuaj yeem teeb pom kev. Nws yuav siv sij hawm ntau lub voj voog hluav taws xob (tsis ua haujlwm) rau MIL kom qhib.

Tej zaum ua rau

Qee qhov laj thawj rau P0819 teeb meem code:

• Teeb meem Sensor: Faulty sensors lub luag hauj lwm rau kis iav ntau yam ntaub ntawv yuav ua rau correlation yuam kev.
• Cov teeb meem thaiv kab hluav taws xob: qhib, luv luv, lossis kev puas tsuaj rau cov xaim txuas nrog cov sensors thiab lub zog hluav taws xob tswj module (PCM) tuaj yeem ua rau cov ntaub ntawv tsis raug.
• PCM faults: Teeb meem nrog lub kis tau tus mob tswj module nws tus kheej tuaj yeem ua yuam kev hauv kev txhais cov ntaub ntawv iav ntau yam.
