WARNING: This page is about a different car, the 2018 Jaguar XE. 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. All sensors should be within 20 deg°C of each other
- Intake air temperature
- Charge air cooler temperature
- Ambient air temperature and manifold air temperature sensors
- Check the intake air temperature sensor (part of the mass air flow sensor) and circuit for sensor contamination
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Refer to the electrical circuit diagrams and check connections are secure and wiring integrity
- Check and install a new sensor that is biassed higher or lower than the other sensors
- Using the manufacturer approved diagnostic system, clear all stored DTCs and retest
- Test the vehicle over 3 drive cycles (engine on/off) across varied driving conditions to confirm the repair
