What P011D means
This is the bank 2 counterpart of P011C and only exists on engines with two separate intake paths, each with its own charge air cooler temperature sensor and intake air temperature sensor – for example V engines with twin turbochargers and separate charge air coolers. After a long standstill both bank 2 sensors should read nearly the same; if they disagree at start-up, without either showing a circuit fault, P011D is set. The code does not identify which sensor is wrong. No manufacturer document using exactly this code was found; the check follows the same principle Ford uses for bank 1 after 6 hours, with a preheater suspending it.
P011D at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of P011D
- Check engine light on
- Usually no change in driving
- Code often returns only after an overnight soak
Common causes of P011D
- Most likelyBank 2 charge air cooler temperature sensor drifting, oily or stuck
- PossibleBank 2 intake air temperature sensor drifting
- PossibleContact resistance at connector or ground
- Less likelyUndetected preheating or uneven cooling
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P011D 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. |
| 1D | The exact fault in that area. |
What to do next
- Note P011D 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 P011D
What does P011D mean?
P011D means "Charge Air Cooler Temperature/Intake Air Temperature Correlation Bank 2". This is the bank 2 counterpart of P011C and only exists on engines with two separate intake paths, each with its own charge air cooler temperature sensor and intake air temperature sensor – for example V engines with twin turbochargers and separate charge air coolers. It is a generic code, so it means the same on every make.
Is it safe to drive with P011D?
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 P011D fail an emissions test?
Yes, it can. P011D 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 P011D to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P011D 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.
