What P007A 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. P007A is the general circuit fault of the bank 1 sensor; low and high signals have their own codes. No manufacturer description naming this exact code was found.
P007A 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 P007A
- Check engine light on
- Reduced power possible, especially on diesels
- Often no noticeable symptoms
Common causes of P007A
- Most likelyConnector or wiring faulty, oil in the connector from crankcase vapours
- Most likelySensor faulty
- PossibleGround or 5 V supply disturbed (often shared with the boost pressure sensor)
- Less likelyEngine control module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P007A 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. |
| 7A | The exact fault in that area. |
What to do next
- Note P007A 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 P007A
What does P007A mean?
P007A means "Charge Air Cooler Temperature Sensor Circuit 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 P007A?
Drive gently and only to a workshop. With P007A the car can go into limp mode (reduced power) to protect itself.
Will P007A fail an emissions test?
Yes, it can. P007A 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 P007A 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 P007A 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.
