P011C Charge Air Cooler Temperature/Intake Air Temperature Correlation Bank 1
On turbocharged engines a charge air cooler temperature sensor sits downstream of the compressor, usually after the charge air cooler, and intake air temperature sensor 1 sits upstream near the air filter. While driving they differ by design, because compression heats the air. After a long standstill, however, both should read nearly the same, so the check runs at start-up. P011C is set when the two bank 1 sensors disagree there, without naming the faulty one. No manufacturer document using exactly this code was found; Ford performs the same comparison after 6 hours (tolerance about 17 °C on petrol, 16 °C on the 2023 diesel) but reports the outlier as P007B, P0111 or P00CE.
Likely causes
Symptoms
- Check engine light on
- Usually no change in driving
- Code often returns only after an overnight soak
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
