\n<\/a><\/p>\n

Function Explanation (DTC Detection Outline)<\/p>\n

\u2022 If low oil pressure continues, engine oil cannot be sent to each oil gallery which could damage the engine. If high oil pressure continues, excess engine oil is dispersed from the oil jet valve into the cylinder which could cause poor environmental performance and fuel economy.<\/div>\n
\u2022 The PCM determines that the engine oil pressure is abnormal and stores a DTC if the actual oil pressure value does not get closer to the target oil pressure value.<\/div>\n
