P011C code meaning
Charge Air Cooler Temperature/Intake Air Temperature Correlation Bank 1
Powertrain system Generic code P01xx codes Check engine light
What P011C means
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 gasoline, 16 °C on the 2023 diesel) but reports the outlier as P007B, P0111 or P00CE.
P011C at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P011C
- Check engine light on
- Usually no change in driving
- Code often returns only after an overnight soak
Common causes of P011C
- Most likelyCharge air cooler temperature sensor drifting, oily or stuck
- PossibleIntake air temperature sensor 1 drifting
- PossibleContact resistance at connector or shared ground
- Less likelyUndetected preheating or uneven cooling (sun, residual heat)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P011C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 1 | Area: fuel and air metering. |
| 1C | The exact fault in that area. |
What to do next
- Note P011C and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P011C
What does P011C mean?
P011C means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with P011C?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P011C fail an emissions test?
Yes, it can. P011C is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P011C to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P011C clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
