TEST
1 NOTE: Before continuing the following test, always check the Air Pump
Assembly in-line connectors. Ensure that there is no terminal damage,
corrosion or backed out terminals. Verify that there is good wire to terminal
connection in the connector.
Start the engine.
With the DRBIII , read the MAF Sensor voltage.
Is the voltage above 4.9267 volts?
Yes → Go To 2
→ Refer to the INTERMITTENT CONDITION symptom in the
No
2 Turn the ignition off.
Disconnect the MAF Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the MAF Signal circuit and the ASD Relay Output
circuit in the MAF Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the MAF Signal circuit for a short to the ASD Relay
→ Go To 3
No
