Detection Condition

WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors input signal from Knock Sensor (KS) when engine is running. If input voltage at PCM 104-pin harness connector terminals No. 31 and No. 4 are excessively low or high, PCM determines KS circuit is malfunctioning. 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.
