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.
Likely causes
Signal wire shorted to ground
Sensor shorted internally
Engine control module faulty
Symptoms
- Check engine light on
- Usually no noticeable symptoms; substitute value used
- Slightly reduced power through knock protection possible
