DTC P007B-29: Charge Air Cooler Temperature Sensor Circuit Range/Performance (Bank 1) - Signal invalid Signal invalid: 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 sensors should be within 20 deg°C of each other
- Refer to appropriate electrical circuit wiring diagrams and check for fuse failure, install a new fuse as required
- Refer to appropriate electrical circuit wiring diagrams and check the charge air 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 charge air temperature sensor as required
- Refer to appropriate electrical circuit 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 appropriate electrical circuit 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 all stored DTCs using the 'Diagnosis Menu' tab and retest
