Powertrain system Generic code P00xx codes Check engine light
What P00E7 means
After a long standstill (six hours in a documented case) all intake air temperature sensors, for example intake air, charge air cooler and manifold temperature, should read about the same. The control module compares them in pairs: if one sensor stands out, it sets that sensor's own plausibility code. This code is set when no pair agrees, so no single sensor can be identified as faulty. A detected engine preheater suspends the test. Since it runs only after a long standstill, the code may take a night to return after being cleared. No manufacturer description naming this exact code was found; bank 2 codes are intended for engines with two separate intake paths.
P00E7 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P00E7
- Check engine light on
- Usually no drivability symptoms
Common causes of P00E7
- PossibleOne temperature sensor drifting without setting its own code
- PossibleUneven cooling, undetected preheater or strong sunshine
- PossibleShared ground or reference line disturbed, falsifying several sensors
- Less likelyEngine control module or software
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P00E7 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. |
| E7 | The exact fault in that area. |
What to do next
- Note P00E7 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 P00E7
What does P00E7 mean?
P00E7 means "Intake Air Temperature Measurement System - Multiple Sensor Correlation Bank 2". After a long standstill (six hours in a documented case) all intake air temperature sensors, for example intake air, charge air cooler and manifold temperature, should read about the same. It is a generic code, so it means the same on every make.
Is it safe to drive with P00E7?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P00E7 fail an emissions test?
Yes, it can. P00E7 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 P00E7 to fix?
Difficulty: medium. A typical repair takes 0.5 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P00E7 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.
