P011CCharge Air Cooler Temperature/Intake Air Temperature Correlation Bank 1

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Needs a drive cycle to confirm a fix
How the car detects it
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.
What you may notice
  • Check engine light on
  • Usually no change in driving
  • Code often returns only after an overnight soak
Likely causes
  • LikelyCharge air cooler temperature sensor drifting, oily or stuck
  • PossibleIntake air temperature sensor 1 drifting
  • PossibleContact resistance at connector or shared ground
  • RareUndetected preheating or uneven cooling (sun, residual heat)
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
Repair
Easy · Often possible to do yourself.Typical cost: €50 – €300
