Inspection Procedure

INSPECTION PROCEDURE

1. Check voltage between terminals THA and E2 of Engine Control Module connector.





- Connect the Check Harness A.
- Turn ignition switch ON.
- Measure voltage between terminals THA and E2 of Engine Control Module connector.

At 20° C (68°F): 0.5 to 3.4 volts
At 80° C (176°F): 0.2 to 1.0 volts

- If OK check for momentary interruption.
- If not OK proceed to step 2.
2. Check Intake Air Temperature Sensor.





- Disconnect the Volume Air Flow Meter connector.
- Measure resistance between terminals 1 and 2 of Volume Air Flow Meter connector.





- If OK proceed to step 3.
- If not OK replace Intake Air Temperature Sensor (Replace Volume Air Flow Meter).
3. Check for open and short in harness and connector between Engine Control Module and Intake Air Temperature Sensor.
- If OK check and replace Engine Control Module.
