P007B Charge Air Cooler Temperature Sensor Circuit Range/Performance Bank 1
Charge air cooler temperature sensor reading on bank 1 is electrically valid but implausible — does not match expected behavior under load, ambient conditions or after long soak.
Is it safe to drive with P007B?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySensor reading drifted
- Less likelySensor element aged beyond calibration window
