TEST
1 Turn the ignition on.
With the DRBIII , read the IAT voltage.
Is the voltage above 4.6 volts?
Yes → Go To 2
→ Refer to the INTERMITTENT CONDITION symptom in the
No
2 Turn the ignition off.
Disconnect the IAT Sensor harness connector.
Turn the ignition on.
Measure the voltage of the (K21) IAT Sensor Signal circuit in the IAT Sensor harness
connector.
