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. P00F0: The signal is above its valid range, i.e. very high resistance from an open circuit; the control module then reads an extremely low temperature. No manufacturer description naming this exact code was found; bank 2 codes are intended for engines with two separate intake paths.

Likely causes

Open circuit, connector off or corroded
Sensor open internally
Ground wire interrupted or control module faulty

Symptoms

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

Repair estimate
