P007FCharge Air Cooler Temperature Sensor Bank1/Bank2 Correlation
- 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. P007F occurs only on engines with two charge-air paths or two charge air coolers, such as twin-turbo V engines: the sensors for bank 1 and bank 2 deviate too far from each other. No manufacturer description naming this code was found; it follows the general rule for plausibility checks of input sensors. Possible causes are a faulty or oily sensor on one bank or a problem in only one charge-air path.
- What you may notice
- Check engine light on
- Reduced power possible, especially on diesels
- Often no noticeable symptoms
- Likely causes
- LikelySensor on one bank faulty or oil-coated
- PossibleLeak or contamination in only one charge-air path
- PossibleConnector fault
- 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
