What P00EA means
Intake air temperature sensor 3 is a third air temperature sensor in the intake path. On documented turbocharged engines with a humidity sensor it is the manifold temperature sensor behind the charge air cooler, an NTC thermistor read directly by the engine control module and used for cylinder filling and ignition timing. The numbering of intake air temperature sensors differs between manufacturers. P00EA: The signal is below its valid range, i.e. very low resistance from a short to ground; the control module then reads an extremely high temperature.
P00EA at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of P00EA
- Check engine light on
- Usually no noticeable symptoms; substitute value used
- Slightly reduced power through knock protection possible
Common causes of P00EA
- Most likelySignal wire shorted to ground
- PossibleSensor shorted internally
- 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 P00EA 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. |
| EA | The exact fault in that area. |
What to do next
- Note P00EA 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 P00EA
What does P00EA mean?
P00EA means "Intake Air Temperature Sensor 3 Circuit Low Bank 1". Intake air temperature sensor 3 is a third air temperature sensor in the intake path. It is a generic code, so it means the same on every make.
Is it safe to drive with P00EA?
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 P00EA fail an emissions test?
Yes, it can. P00EA 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 P00EA to fix?
Difficulty: easy. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P00EA 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.
