P007A
Charge Air Cooler Temperature Sensor Circuit Bank 1
Turbo / charge-air cooling
Generic OBD-II
Low
What it means
P007A indicates a fault in the bank 1 charge-air-cooler (intercooler) temperature sensor circuit. This sensor measures the temperature of the compressed intake air after the intercooler, which the ECM uses to fine-tune boost and fueling. A circuit fault usually causes only a warning light and minor performance changes — it does not prevent the engine from running or starting.
Low
Can I keep driving? Generally safe to drive; you may notice slightly reduced performance, but the engine runs normally.
Common symptoms
What you'll notice
- Check-engine light on
- Possible slight loss of power or sluggish acceleration
- Often no noticeable driving symptoms beyond the warning light
Common causes
Most likely first
- Faulty charge-air-cooler (intercooler) temperature sensor, bank 1Likely
- Open or short in the sensor circuit wiringCommon
- Corroded or loose connector at the sensorCommon
- Damaged wiring near the intercoolerLess often
- Failed ECM/PCM input (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check the sensor's reported charge-air temperature for a plausible value.
- Inspect the sensor connector and wiring near the intercooler for damage or corrosion.
- Check the circuit for an open or short back to the module.
- Measure sensor resistance against spec; replace the sensor if out of range.
- Repair any wiring/connector fault, clear the code, and road-test.
