Air Temperature Sensor
- Connect ohmmeter across pins 30 and 33 in control unit connector. With air temperature at 68°F (20° C), resistance should be 2100-2900 ohms. If not correct, repeat test at air flow meter terminals. Repair harness or replace meter as necessary. See Figure.
- Connect ohmmeter between ground and pin 30 at connector. No continuity should be present. Repeat check at air flow meter terminal and body. Repair harness or replace meter as necessary.
