Charge Air Cooler Temperature Sensor Circuit Intermittent/Erratic Bank 1
What it means
P007E means the signal from the Bank 1 charge-air-cooler (intercooler) temperature sensor is intermittent or erratic. On a turbo or supercharged engine this sensor reports the temperature of the compressed intake air after the intercooler, which the computer uses to fine-tune fueling and boost. An unstable signal usually points to a loose connector or chafed wiring rather than the sensor itself, and the effect on driving is typically minor.
Can I keep driving? Yes — the car drives normally; an intermittent charge-air temperature signal may cause occasional minor boost or fuel adjustments, but rarely anything you'll feel.
Common symptoms
What you'll notice
- Check-engine light on (may come and go)
- Occasional slight change in throttle response or boost under load
- Intermittent, hard-to-reproduce behavior
Common causes
Most likely first
- Loose or corroded connector at the charge-air-cooler temperature sensorLikely
- Intermittent open or short in the sensor wiring (often heat- or vibration-related)Common
- Failing charge-air-cooler temperature sensorCommon
- Failed ECM (rare)Less often
How to diagnose & fix
Work through it in order
- Confirm the code and wiggle-test the sensor connector and harness while watching live data.
- Clean and reseat the connector; look for corrosion or spread pins.
- Inspect wiring routed near hot or vibrating areas for chafing.
- Replace the charge-air-cooler temperature sensor if the signal stays erratic.
- Clear and monitor, since intermittent faults can take time to reappear.
