DTC 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 2015 Jaguar XK, 2014 Jaguar XK, 2013 Jaguar XK, and 2012 Jaguar XK. 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 manufacturer approved diagnostic system 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 manufacturer approved diagnostic system clear all stored DTCs using the 'Diagnosis Menu' tab and retest
