Monitoring Procedure
Input signal of MAF (P0102, P0103), MAP (P0107, P0108), IAT (P0112, P0113), ECT (P0117, P0118), TP (P0122, P0123, P0222, P0223), knock sensor (P0327, P0328), APP (P2122, P2123, P2127, P2128) and barometric pressure sensor (P2228, P2229) are checked for open, short of circuit by monitoring input voltage.
