Possible Causes
WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, and 2016 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
- Purpose of the DTC
- To monitor post selective catalyst reduction soot sensor is capable of collect soot, component protection
- Electrical interdigital electrode monitoring, component protection
- Post selective catalyst reduction soot sensor status communication to powertrain control module interrupted, component protection
- Electrical Cause
- Yes
- Mechanical Cause
- Yes
- Control Module Cavity
- Circuit reference CAN_L_3
- Circuit reference CAN_3_H
- Circuit reference SCRMRLY (powerfeed to post selective catalyst reduction soot sensor)
- Monitor Description
- Post selective catalyst reduction soot sensor removed from exhaust gas flow or blocked
- Functional interdigital electrode self diagnostic error of particulate
- Post selective catalyst reduction soot sensor signal is not valid
- Prioritised List of Possible Causes
- The powertrain control module has received an indication about the component that indicates a failure e.g. an intelligent actuator or sensor is indicating an internal fault
- CAN_L_3 circuit short circuit to ground, short circuit to power, open circuit, high resistance
- CAN_3_H circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Post selective catalyst reduction soot sensor circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Post selective catalyst reduction soot sensor blocked
- Post selective catalyst reduction soot sensor removal from exhaust gas flow
- Post selective catalyst reduction soot sensor failure
- DPF damage
