The PM Sensor Module detects and reports to the PCM that the supply voltage from the sensor module to the electrodes of the sensor probe is above a calibrated threshold for 0.6 seconds. The PCM will light the Malfunction Indicator Lamp (MIL) if this diagnostic runs and fails in 2 consecutive drive cycles. The PCM will turn off the MIL when the diagnostic runs and passes in 4 consecutive drive cycles.
