- How the car detects it
- 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. P00EC: The signal jumps faster than a real temperature can change, which typically points to a loose contact.
