P042F An Rufe Ikon Gudanar da Iskar Gas

OBD-II Lambar Matsala - P042F - Takardar Bayanai

P042F - Ikon sake zagayowar iskar gas ya makale a rufe

Menene ma'anar DTC P042F?

Wannan lambar rikitarwa ce ta matsalar matsala (DTC) wacce ta dace da motocin OBD-II. Wannan na iya haɗawa, amma ba'a iyakance shi ba, Ford, Chevrolet / GM / Cummins, Dodge / Ram, Isuzu, Pontiac, Toyota, BMW, Mercedes, da dai sauransu Yayin janar, madaidaicin matakan gyara na iya bambanta da shekara, iri da samfura. da daidaitawar watsawa.

Idan abin motarka ya adana lambar P042F, yana nufin cewa tsarin sarrafa wutar lantarki (PCM) ya gano matsala tare da tsarin kula da bawul ɗin iskar gas (EGR).

A cikin yanayin P042F, bawul ɗin yana bayyana (ga PCM) makale a cikin rufaffiyar wuri. Nadin A yana nufin wani matsayi ko mataki na saukar da ƙa'idar bawul na EGR, wanda aka bayyana a ƙasa.

EGR ne ke da alhakin ba da damar injin ya cinye wasu man da ba a ƙone ba daga tsarin shaye -shaye. Recraculation Gas Exhaust (EGR) yana da mahimmanci don rage matakan cutarwa na nitrogen oxide (NOx) daga injin mai da injin dizal.

Jigon tsarin sake dawo da iskar gas ɗin shine bawul mai sarrafa lantarki (EGR) wanda ke buɗe don ba da damar iskar gas ta sake komawa cikin shigar injin. PCM yana amfani da bayanai daga Sensor Matsayin Maɗaukaki (TPS), Sensor Speed ​​Vehicle (VSS), da Crankshaft Position (CKP) don sanin lokacin da yanayi ya dace don buɗe / rufe bawul ɗin EGR.

Motoci masu wannan lambar suna sanye da bawul ɗin saukar da iskar gas. Bawul ɗin EGR na ƙasa yana aiki a matakai daban -daban dangane da buɗe maƙura, nauyin injin da saurin abin hawa.

A kan wasu samfura, PCM ɗin kuma yana kula da matsayin mai raɗaɗɗen valve na EGR. Idan matsayin valve na EGR da ake so (ta umurnin PCM) ya bambanta da ainihin matsayin, za a adana lambar P042F kuma fitilar mai nuna rashin aiki (MIL) na iya haskakawa. Sauran motocin suna amfani da bayanai daga Manifold Air Pressure (MAP) da / ko EB firikwensin matsin lamba (DPFE) EGR don tantance ko bawul ɗin EGR yana cikin matsayin da ake so (ko a'a). Yawancin abubuwan hawa za su ɗauki da'irar ƙonewa da yawa (tare da matsala) kafin MIL ta haskaka.
