- Turn ignition switch OFF.
- Remove EVAP control system pressure sensor with its harness connector.Always replace O-ring with a new one.
- Install a vacuum pump to EVAP control system pressure sensor.
- Turn ignition switch ON and check output voltage between ECM harness connector terminals under the following conditions.
