P0749 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0749 qhia tias muaj teeb meem sib cuam tshuam / sib cuam tshuam hauv kev sib kis siab tswj solenoid valve "A" Circuit Court.

Qhov txhaum cai txhais li cas P0749?

Teeb meem code P0749 qhia tias muaj teeb meem nrog kev sib kis ntawm cov kua dej siab tswj solenoid valve "A" hauv lub tsheb tsis siv neeg kis. Cov cai no qhia tau hais tias tsis muaj qhov hluav taws xob tsis txaus ntawm lub solenoid valve, uas tuaj yeem ua rau kev ua haujlwm tsis zoo thiab lwm yam teeb meem sib kis. Lub solenoid valve tswj kev sib kis ntawm cov dej siab, thiab yog tias nws cov hluav taws xob hluav taws xob tsis nyob rau hauv kev sib cuag ruaj khov, yuav tsis muaj siab txaus los hloov lub zog.

Tej zaum ua rau

Qee qhov laj thawj rau P0749 teeb meem code:

• Siab tswj solenoid valve malfunction: Lub valve nws tus kheej tej zaum yuav puas los yog malfunctioning vim hnav, corrosion los yog lwm yam teeb meem.
• Kev sib txuas hluav taws xob thiab hluav taws xob: Kev sib txuas xoob, tawg lossis luv luv hauv cov xov hlau, kev sib txuas lossis cov khoom sib txuas tuaj yeem ua rau tsis muaj hluav taws xob txaus rau lub solenoid valve.
• Teeb meem nrog lub kis tau tus mob tswj chav tsev: Kev ua haujlwm tsis zoo lossis kev ua haujlwm tsis zoo hauv kev tswj hwm kev sib kis (TCM) tuaj yeem ua rau muaj teeb meem yuam kev lossis kev tswj tsis raug ntawm lub solenoid valve.
• Teeb meem fais fab: Kev siv hluav taws xob tsis txaus lossis teeb meem ntawm lub tsheb lub roj teeb tuaj yeem ua rau cov khoom siv hluav taws xob, suav nrog cov solenoid valve, ua haujlwm tsis zoo.
• Siab sensors los yog lwm yam kis tau tus mob sensors: Kev ua haujlwm tsis zoo lossis kev ua haujlwm tsis zoo hauv kev sib kis ntawm cov kua dej siab sensors lossis lwm yam kev sib kis ntawm cov sensors tuaj yeem ua rau lub siab tswj tsis raug.
• Teeb meem nrog lub iav hloov mechanism: Kev ua txhaum ntawm lub iav hloov lub tshuab, xws li vim hnav lossis puas, tuaj yeem ua rau P0749.

Cov laj thawj no tuaj yeem kuaj thiab kuaj tau nrog cov cuab yeej tshwj xeeb thiab kev saib xyuas lub tsheb.
