Bincike da warware matsalar

An saita lambar P2447 lokacin da babu iska ta waje don ƙone wuce haddi na hydrocarbons a cikin tsarin shaye-shaye a farkon sanyi. Wannan yana haifar da ƙarfin lantarki a gaban firikwensin iskar oxygen don kada ya faɗi zuwa ƙayyadadden matakin.

Hanyar ganowa yana buƙatar injin ya zama sanyi; daidai, motar ta tsaya aƙalla 10-12 hours. Bayan haka, kuna buƙatar haɗa kayan aikin bincike kuma fara injin.

Wutar lantarki a gaban firikwensin oxygen yakamata ya faɗi ƙasa da 0,125 volts a cikin kusan daƙiƙa 5 zuwa 10. Za a tabbatar da kuskure a cikin tsarin iska na biyu idan ƙarfin lantarki bai faɗi zuwa wannan ƙimar ba.

Idan ƙarfin lantarki bai faɗi zuwa 0,125V ba amma kuna iya jin motsin iska yana gudana, duba duk hoses, layuka, bawuloli, da solenoids don leaks. Hakanan tabbatar da duba duk hoses, layi da bawuloli don toshewa kamar ginawar carbon ko wasu toshewar.
