Detection Condition

WARNING: This page is about a different car, the 2003 Mazda MPV and 2002 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors Crankshaft Position (CKP) sensor input signal interval time. PCM calculates change in interval time for each cylinder. If change of interval time exceeds preprogrammed criteria, PCM detects misfire in corresponding cylinder. While engine is running, PCM counts number of misfires that occurred at 200 crankshaft revolutions and 1000 crankshaft revolutions and calculates misfire ratio for each crankshaft revolution. If ratio exceeds preprogrammed criteria, PCM determines misfire has occurred, which can cause damage to catalytic converter and affect emission system performance. This is a continuous monitor. MIL illuminates if PCM detects malfunction in 2 consecutive drive cycles.
