WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, 2016 Land Rover Range Rover, 2014 Land Rover Range Rover, and 2013 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
- Leave vehicle turned off for a minimum of 8 hours and allow to soak to a stable temperature. Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signals - Ambient Air Temperature (0xF446) - Engine Coolant Temperature (0xF405) - Boost Air Temperature Raw Physical Value (0x0341) - Intake Air Temperature (0xF40F) - Engine Coolant Temperature #2 (0x0489). All values should be within 20°C of each other
- Refer to appropriate system wiring diagram and check the manifold absolute pressure and temperature 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 manifold absolute pressure and temperature sensor as required
- Check and install a new sensor that is biased higher or lower than the other sensors
- Check and install a new a changeover valve - Fuel Fired Booster Heater (FFBH) system
- Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest
