Detection Condition

PCM monitors input signal from Knock Sensor (KS) when engine is running. If input voltage between PCM 30-pin harness connector terminals "2P" and "2S" is more than 4.9 volts, PCM determines that KS circuit has malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition during first drive cycle. PENDING CODE is available if PCM detects malfunction condition. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
