Intake Air Temperature Sensor

TEST PROCEDURE:

Status Monitoring:
With the engine at operating temperature, the intake air temperature should be between 122° and 158°F (50° to 70°C); ambient air temperature 73°F ± 9° (23 +/- 5 C).

A display below -40°F (-40°C) indicates a break in the temperature sensor or in the supply wire to the Digital Motor Electronic (DME) control unit.
