TEST
1 Start the engine.
With the DRBIII , read the MAP Sensor voltage.
Is the voltage above 4.9 volts?
Yes → Go To 2
→ Refer to the INTERMITTENT CONDITION symptom in the
No
2 Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K1) MAP Signal circuit and the (K6) 5 Volt
Supply circuit in the MAP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the (K1) MAP Signal circuit for a short to the (K6) 5 Volt
→ Go To 3
No
