P007B-23: Charge Air Cooler Temperature Sensor Circuit Range/Performance (Bank 1) - Signal stuck low: Action
- 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 applicable SYSTEM WIRING DIAGRAM(S) and check the manifold absolute pressure and 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 manifold absolute pressure and temperature sensor as required
- Using the manufacturer approved diagnostic system clear all stored DTCs using the `Diagnosis Menu' tab and retest
