Commonly used with many 1979 newer gm vehicles.
Gm iat sensor pinout.
Lance one thing to keep in mind is the ecu microcontroller has a d references that are normally tied to the sensor voltage.
Iat sensors have no polarity so it does not matter which wire you connect to which pin.
Gm iat sensor with open element are proper gm style sensors for use with all megasquirt ms3pro ecus and include a 6 wire pig tail with weatherproof connector.
Gm iat sensor with open element is the recommended fast response intake air temp sensor iat for use on forced induction vehicles.
We also really like the efi connection for gm connectors.
Ideally these are at 0 and 5 volts but are by design ratiometric so if there is a load on the sensor output and it drags the voltage down the references will be pulled down by the same amount.
The following two sections list the supported sensors.
