EVAP control system pressure sensor
1. Remove EVAP control system pressure sensor from bracket with its harness connector connected.
2. Remove hose from EVAP control system pressure sensor.
3. Apply vacuum and pressure to EVAP control system pressure sensor with pump as shown in figure.
4. Check output voltage between terminal (52) and (25) (ECM ground).
CAUTION:
-
Always calibrate the vacuum pump gauge when using it.
-
Do not apply below -20 kPa (-150 mmHg, -5.91 inHg) or over 20 kPa (150 mmHg, 5.91 inHg) of pressure.
5. If NG, replace EVAP control system pressure sensor.
