COMPONENT INSPECTION
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. Use pump to apply vacuum and pressure to EVAP control system pressure sensor as shown in figure.
4. Check output voltage between ECM terminal (62) and engine ground.
CAUTION:
-
Always calibrate the vacuum pump gauge when using it.
-
Do not apply vacuum below -20 kPa (-150 mmHg, -5.91 inHg) or pressure over 20.0 kPa (150 mmHg, 5.91 inHg).
5. If NG, replace EVAP control system pressure sensor.
