Intake Air Temperature Sensor
TEST PROCEDUREStatus 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.
Resistance Test
Connect universal adapter. Measure resistance across the terminals 44 and 26. Refer to Air Temperature Sensor. Specifications
