Comprehensive Component (Engine Input) Monitor

Monitoring Procedure

Input signals of MAF (P0102 / P0103), MAP (P0107 / P0108 / P1107 / P1108), IAT (P0112 / P0113), ECT (P0117 / P0118), TP (P0122 / P0123), Knock sensor (P0327 / P0328), Fuel tank pressure sensor (P0452 / P0453), Fuel vapor temp. sensor (P2026 / P2027), Fuel level sensor (P0463) and Barometric pressure sensor (P2227 / P2228 / P2229) are checked for open, short of circuit by monitoring input voltage.
