P00E8 Intake Air Temperature Sensor 3 Circuit Bank 1

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. P00E8: This is the general circuit fault; low and high signals have their own codes. No manufacturer description naming this exact code was found.

Likely causes

Symptoms

• Check engine light on
• Usually no noticeable symptoms; substitute value used
• Slightly reduced power through knock protection possible

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
