- First Diagnostic:
The PM Sensor module detects and reports to the PCM that the boost voltage on the supply circuit between the sensor module and the particulate measuring electrodes in the probe goes above 2.0 Volts for 3 seconds.
- Second Diagnostic:
The PM Sensor probe temperature is below 44°C (112°F), or the difference between probe temperature and EGT Sensor 1/5 temperature is above 43°C (109°F).
- The difference between the PM Sensor probe temperature and the modeled temperature is below 104°C (220°F) or is above 75°C (167°F).
