    Does anyone know which pins on the ecu connector goto the iat sensor on the smart fortwo 450?

    The Evilution site says 53 and 17 but theres nothing in number 53 and number 17 is a different colour wire to whats at the iat sensor

    Thanks

    What kind of car is it? CDI, petrol, Brabus or nonBrabus? In fact, everyone needs to know what the car is all about ...
    The IAT sensor is connected to an ECU (Smart450 has EDG for diesel and MEG for petrol) through a pin connector with pin numbers - MB Star shows the connector and the way the pins are numbered.

          MEG.
          The connector leaves a color, the sensor gets the same color of thread (on the original). Check with a buzzer wires 17 and 53.
          Check the IAT with ohmmeter, http://smartmaniacs.co.uk/forum/the-...786-iat-sensor .
