Air Temperature Sensor
- Ensure ignition is off. Disconnect electrical connector from air temperature sensor. Air temperature sensor is located in air intake, near air filter.
- Remove air temperature sensor. Place threaded end of air temperature sensor and thermometer in container of water. Attach ohmmeter between air temperature sensor electrical terminals.
- Heat water and note that resistance is within specification in relation to temperature. See Fig 1. Replace air temperature sensor if defective.
NOTE:
Coolant temperature sensor may also be referred to as Engine Coolant Temperature (ECT) sensor.
