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
- Monitoring of the rail pressure governor deviation for rail pressure too high
- Monitoring of pressure control valve operation
- Electrical Cause
- Yes
- Mechanical Cause
- Yes
- Control module cavity
- Circuit reference O_T_MEU
- Circuit reference O_T_PCV
- Monitor Description
- Negative rail pressure governor deviation is below a threshold and rail pressure governor is below a threshold
- Prioritised List of Possible Causes
- The powertrain control module measured a signal voltage above a specified range but not necessarily a short circuit to power, gain too high
- Other fuel pressure related DTCs
- Fuel lines restricted
- Fuel lines leakage
- Fuel injector stuck open/leaking
- Fuel rail pressure sensor circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Fuel volume control valve circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Fuel pressure control valve circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Fuel rail pressure sensor failure
- Fuel volume control valve failure
- Fuel pressure control valve failure
