TEST
4
Turn the ignition off.
Disconnect the Boost Pressure Sensor harness connector.
Disconnect the ECM harness connectors.
Measure the resistance between ground and the Boost Pressure Sensor Signal
circuit.
Is the resistance above 100 kohms?
Yes → Go To 5
→ Repair the Boost Pressure Sensor Signal circuit for a short to
No
