What P007E 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. P007E is set when the signal jumps beyond a plausible rate of change, which typically points to a loose contact.
P007E 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 P007E
- Check engine light on
- Reduced power possible, especially on diesels
- Often no noticeable symptoms
Common causes of P007E
- Most likelyLoose contact or corroded connector
- PossibleWire chafed at the engine
- PossibleSensor faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P007E 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. |
| 7E | The exact fault in that area. |
What to do next
- Note P007E 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 P007E
What does P007E mean?
P007E means "Charge Air Cooler Temperature Sensor Circuit Intermittent/Erratic Bank 1". 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 P007E?
Drive gently and only to a workshop. With P007E the car can go into limp mode (reduced power) to protect itself.
Will P007E fail an emissions test?
Yes, it can. P007E 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 P007E 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 P007E 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.
