Charge Air Cooler Temperature/Intake Air Temperature Correlation Bank 2
What it means
P011D means the charge air cooler temperature sensor on bank 2 and the intake air temperature sensor don't agree the way they should — typically at key-on after the engine has cooled, when both should read close to the same temperature. It usually points to one sensor drifting or a wiring issue rather than any mechanical fault, and the engine keeps running normally.
Can I keep driving? Safe to drive — this is a sensor-plausibility check; the engine runs normally and it mainly signals that two temperature readings disagree.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

Common symptoms
What you'll notice
- Check-engine light on
- Usually no noticeable drivability change
- Possible minor loss of fuel economy or slight performance change
Common causes
Most likely first
- Faulty or drifting charge air cooler temperature sensor on bank 2Likely
- Faulty or drifting intake air temperature sensorCommon
- Corroded connector or poor connection at either sensorCommon
- Wiring fault affecting one sensor's readingLess often
- One sensor reading stale because airflow past it is blocked or restrictedLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and compare the two temperature sensor readings after a cold soak — they should agree closely at key-on.
- Inspect both sensors' connectors and wiring for corrosion or damage.
- Check that airflow past each sensor isn't blocked by debris.
- Replace whichever sensor reads implausibly against a known-good reference or the other sensor.
- Clear the code and re-run a cold-start drive cycle to confirm.
