DTC P0073 - Takardar bayanan OBD-II

Yanayin Sensor Circuit High Signal

Menene ma'anar lambar matsala P0073?

Wannan Deric Genication Transmission / Engine DTC galibi ya shafi duk injunan da ke sanye da OBDII, amma ya fi yawa a wasu Audi, BMW, Chrysler, Dodge, Ford, Jeep, Mazda, Mitsubishi da VW.

Na'urar zazzabi ta yanayi (AAT) tana jujjuya yanayin zazzabi zuwa siginar lantarki zuwa tsarin sarrafa wutar lantarki (PCM). Ana amfani da wannan shigarwar don canza aikin tsarin kwandishan da nuna zafin waje.

PCM yana samun wannan shigarwar kuma mai yiwuwa ƙarin biyu; Shigar da zazzabi na iska (IAT) da firikwensin injin injin (ECT). PCM ɗin yana duba ƙarfin ƙarfin firikwensin AAT kuma yana kwatanta shi da karatun firikwensin IAT / ECT lokacin da aka fara kunna wutar bayan dogon sanyi. An saita wannan lambar idan waɗannan bayanan sun bambanta sosai. Hakanan yana bincika siginar ƙarfin lantarki daga waɗannan firikwensin don sanin ko daidai ne lokacin da injin ya cika ɗumi. Yawancin lokaci ana saita wannan lambar saboda matsalolin lantarki.

Matakan matsala na iya bambanta dangane da mai ƙira, nau'in firikwensin AAT, da launuka na waya.
