P011C Charge Air Cooler Temperature/Intake Air Temperature Correlation Bank 1

Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modeNo

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

Charge air cooler temperature sensor drifting, oily or stuck
Intake air temperature sensor 1 drifting
Contact resistance at connector or shared ground
Undetected preheating or uneven cooling (sun, residual heat)

Symptoms

  • Check engine light on
  • Usually no change in driving
  • Code often returns only after an overnight soak
