Charge Air Cooler Temperature Sensor Circuit High Bank 1
What it means
P007D means the ECM saw an abnormally high signal voltage from the bank 1 charge air cooler (intercooler) temperature sensor, which usually points to an open or high-resistance circuit. This sensor measures the temperature of the compressed intake air after the intercooler so the ECM can fine-tune boost and fueling. The car drives normally on a default value, but the fault trips the check-engine light.
Can I keep driving? Yes — the car drives normally. The ECM uses a default charge-air temperature value, so the main effect is a check-engine light and possibly slightly less-than-optimal boost control.

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 change in how the car drives
- Occasionally slightly reduced performance on boost (turbo/supercharged engines)
Common causes
Most likely first
- Open circuit or high-resistance connection in the sensor wiring (high signal usually means open)Likely
- Faulty charge air cooler temperature sensorCommon
- Corroded or disconnected sensor connectorCommon
- Faulty ECM/PCM input (rare — check wiring and sensor first)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the code is current.
- Inspect the charge air cooler temperature sensor connector and wiring for opens, corrosion, or a disconnected plug.
- Check the sensor's signal and ground circuits for continuity back to the ECM.
- Measure the sensor's resistance against spec at a known temperature.
- Repair the wiring or replace the sensor as indicated. Clear and re-test.
