DTC P007B-24: Charge Air Cooler Temperature Sensor Circuit Range/Performance Bank 1 - Signal stuck high: Action
- 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 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
- Refer to appropriate system wiring diagram and check for fuse failure, install a new fuse as required
- Check and install a new manifold absolute pressure and temperature sensor as required
- Refer to appropriate system wiring diagram 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 appropriate system wiring diagram and check the air charge coolant pump for open circuit, high resistance
- Refer to the relevant section of the service information and check the air charge coolant pump for correct operation
- Check and install a new air charge coolant pump 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
