DTC P24AE-96: Particulate Matter Sensor Circuit - Component internal failure: Action
- Vehicle Conditions to enable DTC Logging Strategy
- Monitor runs once when post selective catalyst reduction soot sensor is in regeneration (requires driving for 20 minutes and visible, check 0xD940 ~785°C)
- Prioritized Checks to Perform
- Diagnosis of this DTC may require using the manufacturer approved diagnostic system check datalogger signals
- 0xD940 Particulate Matter Sensor Meander Temperature - Raw
- Refer to the appropriate System Wiring Diagram(s) and check the CAN_L_3 and CAN_3_H circuit for short circuit to ground, open circuit, high resistance
- Refer to the appropriate System Wiring Diagram(s) and check the post selective catalyst reduction soot sensor circuit for short circuit to ground, open circuit, high resistance
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Check post selective catalyst reduction soot sensor for soot deposits on probe
- Check post selective catalyst reduction soot sensor for water deposits on probe
- Check and install a new post selective catalyst reduction soot sensor as required
- Check DPF for substrate damage
- Using the manufacturer approved diagnostic system check powertrain control module for related DTCs and refer to relevant DTC index
