What P007F means
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.
P007F at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1 hours
- Clears after repairAfter a drive cycle
Symptoms of P007F
- Check engine light on
- Reduced power possible, especially on diesels
- Often no noticeable symptoms
Common causes of P007F
- Most likelySensor on one bank faulty or oil-coated
- PossibleLeak or contamination in only one charge-air path
- PossibleConnector fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P007F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 7F | The exact fault in that area. |
What to do next
- Note P007F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P007F
What does P007F mean?
P007F means "Charge Air Cooler Temperature Sensor Bank1/Bank2 Correlation". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P007F?
Drive gently and only to a workshop. With P007F the car can go into limp mode (reduced power) to protect itself.
Will P007F fail an emissions test?
Yes, it can. P007F is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P007F to fix?
Difficulty: easy. A typical repair takes 0.3 to 1 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P007F clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
