P007B-24 - Charge Air Cooler Temperature Sensor Circuit Range/Performance Bank 1 - Signal stuck high: Action
WARNING: This page is about a different car, the 2017 Jaguar XJ, 2016 Jaguar XJ, 2015 Jaguar XJ, 2014 Jaguar XJ, and 2013 Jaguar XJ. 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
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Refer to applicable SYSTEM WIRING DIAGRAMS and check for fuse failure, install a new fuse as required
- Refer to applicable SYSTEM WIRING DIAGRAMS and check the temperature and manifold absolute pressure sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Check and install a new temperature and manifold absolute pressure sensor as required
- Refer to applicable SYSTEM WIRING DIAGRAMS and check the air charge coolant pump and control circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Refer to applicable SYSTEM WIRING DIAGRAMS and check the air charge coolant pump for open circuit, high resistance
- Refer to the relevant service information and check the air charge coolant pump for correct operation. Check and install a new air charge coolant pump as required
- Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest
