    ATS (Air Temp Sensor) Problems, Can U Fix?

    The ATS ( Air Temp Sensor) has thrown a code and when checked with the Snap On VERUS it is reading 306deg...

    As the code was first starting it would only seem to flash when I would hit a bump on the right side of my car then after two days of flashing when hitting bumps it finally stuck and the engine light is now on!

    Hopefully someone has had this experience and has found a fix!

    How to test, wiring diagrams all is appreciated!






    Found this... From here... http://opel-scan.ru/files/DME_1.1_1.3.pdf

    ATS
    The ATS is mounted in the AFS inlet tract and measures the air temperature before it enters the inlet manifold. Because the
    density of air varies in inverse proportion to the temperature, the ATS signal allows more accurate assessment of the volume of
    air entering the engine. However, the ATS has only a minor correcting effect on ECU output.
    The open circuit supply to the sensor is at a 5.0 volt reference level and the earth path is through the AFS earth return circuit.
    The ATS operates on the NTC principle. A variable voltage signal is returned to the ECU based upon the air temperature. This
    signal is approximately 2.0 to 3.0 volts at an ambient temperature of 20° C and reduces to about 1.5 volt as the temperature rises
    to around 40° C.
