Misfire Sensor: Description and Operation
The misfire sensor (California models only) is an electromagnetic inductance coil similar in operation to a camshaft or crankshaft position sensor. A
four-point stator, or pulse ring, located behind the crankshaft damper, generates an electrical impulse in the sensor at each 90 degrees of rotation. The
Powertrain Control Module (PCM) monitors the sensor pulses and flags any misfire events. When a specified number of misfires occur within a certain
time frame, the PCM will alert the driver to the condition by turning on the Malfunction Indicator Light (MIL).
