    Outside Air Temp Sensor affect on Performance ?

    Hi guys,

    Does anybody know if outside air temp sensor affects ECU compensations ?

    Im asking this because i think my sensor is broken, it shows very high temperatures.

    For example real temp is about 29 Celcius, it shows about 47 Celcius.

    Any comments will be appreciated..

    Thanks
    Emre

    IAT (intake air temp) is the important factor for the ECU. The sensor is on the silver "y" intake pipe going to the throttle body. You can hook up a code scanner to see the values.

    Based on that explanation, the outside air temp problem he's experiencing is probably coming from a different sensor.

    Yes, i mean the sensor which measures ambient air temperature.

    Totally different. The sensor for ambient air temperature, which is displayed on the dashboard, is independent of any engine inputs.

    If your ambient temperature sensor is giving you false readings, it is quite possible the sensor is dirty or otherwise fouled. I'm not sure where it is located, but if you find it, a simple cleaning may fix the problem. I've had similar problems with other cars.
