Monitoring Procedure

Input signals for the following sensor circuits are checked for open and short by monitoring input voltage.

• MAF sensor (P0102, P0103)
• IAT sensor (P0112, P0113)
• ECT sensor (P0117, P0118)
• TP sensor (P0122, P0123, P0222, P0223)
• Knock sensor (P0327, P0328)
• APP sensor (P2122, P2123, P2127, P2128)
• Barometric pressure sensor (P2228, P2229)
