EVAP CONTROL SYSTEM PRESSURE SENSOR
1. Remove EVAP control system pressure sensor with its harness connector connected.
2. Remove hose from EVAP control system pressure sensor.
3. Install a vacuum pump to EVAP control system pressure sensor.
4. Turn ignition switch "ON" and check output voltage between ECM terminal 88 and ground under the following conditions.
CAUTION:
-
Always calibrate the vacuum pump gauge when using it.
-
Do not apply below -93.3 kPa (-700 mm Hg, -27.56 in Hg) or over pressure 101.3 kPa (760 mm Hg, 29.92 in Hg) of pressure.
5. If NG, replace EVAP control system pressure sensor.
