Charge Air Cooler Temperature Sensor Circuit Range/Performance Bank 2
CAC temperature sensor reading on bank 2 implausible. Same as P007B on bank 2. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Affected components
- Cac temperature sensor
Common causes
- High likelihood: Sensor reading drifted
- Low likelihood: Sensor element aged beyond calibration window
- Low likelihood: Sensor mounting loose - signal damping
Diagnostic notes
