Daidaitawa tsakanin zafin zafin iska da zafin iska na yanayi

Mene ne wannan yake nufi?

Wannan Generic Powertrain Diagnostic Code Code (DTC) galibi ana amfani da shi ga motocin OBD-II da yawa. Wannan na iya haɗawa, amma ba'a iyakance shi ba, Mercedes-Benz, Jeep, Mazda, Ford, da sauransu.

Idan kuna da lambar P009A jim kaɗan bayan sabis na injin, yana nufin cewa tsarin sarrafa wutar lantarki (PCM) ya gano rashin daidaituwa a cikin siginar da aka haɗa tsakanin firikwensin IAT da firikwensin zafin iska na yanayi. Ya zama dole a kwatanta zafin IAT da iskar yanayi don tabbatar da cewa babu wani cikas da ke toshe kwararar mahimmiyar iska zuwa cin injin.

Na'urorin firikwensin IAT galibi sun ƙunshi thermistor wanda ke fitowa daga gidan filastik akan tushe mai waya biyu. An saka firikwensin a cikin shigar iska ko gidan matatun mai. Tsarin ƙirar firikwensin IAT na biyu yana haɗa na'urar firikwensin a cikin mahalli na iska mai yawa (MAF). Wasu lokutan ana samun maƙarƙashiyar IAT a layi ɗaya tare da MAF waya mai ƙarfi, kuma a wasu lokuta yana cikin hutu daga nesa da iska. Bincika ƙayyadaddun wuri na firikwensin IAT don abin hawa da ake tambaya kafin yin kowane zato.

Yawancin lokaci ana sanya thermistor ɗin don iska ta shiga ta ratsa ta. Galibin jikin firikwensin an tsara shi don a saka shi a cikin abin da aka makala ta cikin bututun roba mai kauri. Yayin da zafin zafin iska ke ƙaruwa, matakin juriya a cikin IAT yana raguwa; haifar da ƙarfin lantarki don kusanci matsakaicin tunani. Lokacin da iska ta yi sanyi, juriya na firikwensin IAT yana ƙaruwa. Wannan yana sa wutar lantarki ta firikwensin IAT ta faɗi. PCM tana ganin waɗannan canje -canje a cikin siginar siginar firikwensin IAT kamar canje -canje a cikin zafin zafin iska.

Na'urar firikwensin zafin yanayi na yanayi tana aiki iri ɗaya kamar na firikwensin IAT. Na'urar firikwensin zazzabi galibi tana kusa da yankin gasa.

Za a adana lambar P009A kuma fitilar mai nuna rashin aiki (MIL) na iya haskakawa idan PCM ta gano siginar wutar lantarki daga firikwensin IAT da firikwensin zafin jiki na yanayi wanda ya bambanta fiye da matsakaicin ƙimar da aka yarda da ita don takamaiman lokacin. Wasu ababen hawa na iya buƙatar gazawar ƙonewa da yawa don haskaka MIL.

Menene tsananin wannan DTC?
