DTC P24C7-64: Particulate Matter Sensor Temperature Circuit Range/Performance - Signal plausibility failure: Action
- Vehicle Conditions to enable DTC Logging Strategy
- Monitor runs 220seconds after post selective catalyst reduction soot sensor completes regeneration (requires driving for around 20 minutes and regeneration end visible via temperature DID D940 drops from 785°C down to ~ 200°C) - keep low rpm
- Prioritized Checks to Perform
- Check post selective catalyst reduction soot sensor for correct installation
- Refer to the appropriate System Wiring Diagram(s) and check the post selective catalyst reduction soot sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Check and install a new post selective catalyst reduction soot sensor module as required
- Refer to the appropriate System Wiring Diagram(s) and check the DPF outlet temperature sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Check SCR catalyst for blockage
- Check exhaust system for mechanical integrity
- Using the manufacturer approved diagnostic system check powertrain control module for related DTCs and refer to relevant DTC index
