Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk abin hawa tun 1996 (Ford, Mazda, Mercedes Benz, da sauransu). Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Lambar da aka adana P0099 tana nufin tsarin sarrafa wutar lantarki (PCM) ya gano shigowar lokaci -lokaci daga da'irar firikwensin iska ta # 2.

PCM yana amfani da shigarwar IAT da shigarwar firikwensin iska (MAF) don lissafin isar da mai da lokacin ƙonewa. Tun da kiyaye madaidaicin rabo na iska / mai (yawanci 14: 1) yana da mahimmanci ga aikin injiniya da tattalin arzikin mai, shigarwar daga firikwensin IAT yana da matukar mahimmanci.

Wasu masana'antun kuma suna haɗa firikwensin IAT a cikin mahalli na firikwensin MAF. A kowane hali, dole ne a sanya shi ta yadda (tare da injin ke gudana) iskar yanayi da aka jawo ta cikin abubuwan da ake amfani da su ta hanyar maƙura za ta iya ci gaba da gudana ta ko'ina.

Mai firikwensin IAT yawanci shine firikwensin thermistor mai waya biyu. Juriya na firikwensin yana canzawa dangane da zafin jiki na iskar da ke ratsa sinadarin waya mai sanyi. Yawancin motocin sanye take da OBD II suna amfani da ƙarfin lantarki (volts biyar na al'ada ne) da siginar ƙasa don rufe da'irar firikwensin IAT. Matakan juriya daban -daban a cikin abubuwan da ake ganewa na IAT suna haifar da jujjuyawar wutar lantarki a cikin da'irar shigarwa. PCM tana fassara waɗannan canjin sauye -sauyen a matsayin canje -canje a yanayin zafin zafin iska.
