P007CCharge Air Cooler Temperature Sensor Circuit Low Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- The charge air cooler temperature sensor (an NTC thermistor) measures the temperature of the compressed charge air at the charge air cooler, depending on the manufacturer upstream or downstream of it, and is often combined with the boost pressure sensor. The engine control module uses it for the air mass calculation, boost control, component protection and to monitor cooler efficiency. P007C: A low signal means low sensor resistance, typically a short to ground; with an NTC sensor the control module then reads an extremely high temperature. Depending on the input circuit of the control module, an open circuit can occasionally also appear as low.
- What you may notice
- Check engine light on
- Reduced power possible, especially on diesels
- Often no noticeable symptoms
- Likely causes
- LikelySignal wire shorted to ground
- LikelySensor shorted internally
- PossibleOil or moisture in the connector
- RareEngine control module faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €80 – €250
