Component Test

1. Disconnect the Air Flow Meter connector.

Air Flow Meter Connector:

2. Using an Ohmmeter, measure the resistance between terminals THA and E2. Compare the readings with the various ambient temperature levels according to the Sensor Resistance Chart.

Checking Intake Air Temperature Sensor Resistance:

Intake Air Temperature Sensor Resistance Chart:

3. If the resistance values are not within the specified levels, replace the Air Flow Meter. The Intake Temperature Sensor is NOT a serviceable component.
4. Reconnect the terminal connector.
