P0505 IAC Idle Air Control System ua haujlwm tsis zoo

P0505 – OBD-II Teeb meem Code Technical Description

Kev ua yuam kev P0505 muaj feem xyuam rau lub tsheb tsis ua haujlwm huab cua tswj (IAC - Idle Air Control). Qhov kev ua yuam kev no qhia txog teeb meem nrog lub cav tsis ua haujlwm ceev tswj.

Qhov txhaum cai txhais li cas P0505?

Teeb meem code P0505 qhia tias muaj teeb meem nrog lub cav tsis ua haujlwm ceev tswj qhov system. Qhov no txhais tau hais tias lub cav tswj module tau kuaj pom muaj teeb meem nrog kev tswj ceev ceev. Thaum cov cai no tshwm sim, nws feem ntau txhais tau hais tias qhov kev tswj hwm huab cua tsis ua haujlwm tsis ua haujlwm zoo.

Tej zaum ua rau

Qee qhov laj thawj rau P0505 teeb meem code:

• Lub kaw lus tsis ua haujlwm tsis raug cai (IAC) lossis tsis ua haujlwm huab cua tswj valve.
• Teeb meem nrog kev xaim lossis kev sib txuas ntawm lub cev muaj zog.
• Kev ua haujlwm tsis zoo ntawm lub throttle valve lossis throttle txoj hauj lwm sensor.
• Configured incorrectly los yog puas coolant kub sensor.
• Teeb meem nrog lub tshuab nqus tsev vacuum los yog xau hauv lub tshuab nqus tsev.
• Muaj ib qho malfunction nyob rau hauv lub tso pa system los yog ib tug clogged cua lim.

Cov no tsuas yog qee qhov ua tau, thiab rau kev kuaj mob kom raug nws raug pom zoo kom ua tiav kev kuaj mob.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0505?

Cov hauv qab no yog qee cov tsos mob tshwm sim thaum koj muaj P0505 teeb meem code:

• Tsis ruaj tsis khov ceev: Lub cav yuav khiav ntawm qhov tsis sib xws lossis txawm tias nres thaum nres.
• Nce idle speed: Lub cav yuav khiav ntawm qhov nrawm dua li qub txawm tias nres.
• Nyuaj hauv kev kho qhov nrawm nrawm: Thaum sim kho qhov nrawm siv IAC lossis lub cev lub cev, cov teeb meem yuav tshwm sim.
• Kev ua haujlwm tsis ruaj khov ntawm lub cav: Lub cav yuav coj tus cwj pwm tsis zoo, tshwj xeeb tshaj yog nyob rau qis qis lossis thaum nres ntawm lub teeb tsheb.

Cov tsos mob no yuav tshwm sim txawv nyob ntawm seb qhov teeb meem tshwj xeeb nrog lub kaw lus ceev ceev thiab lwm yam.

Yuav ua li cas kuaj tau tus lej txhaum P0505?

Thaum kuaj pom DTC P0505, cov kauj ruam hauv qab no raug pom zoo:

1. Txheeb xyuas lwm cov lej yuam kev: Tshawb xyuas lwm cov lej yuam kev uas tej zaum yuav cuam tshuam nrog lub kaw lus tswj kev ceev lossis lwm yam hauv lub cav.
