1.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR

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

   ECM | Condition [Applied vacuum kPa (kg/cm2, psi)] | Voltage (V)
   Connector | + | –
   Terminal | Terminal
   F102 | 78 | 75 | Not applied | 1.8 - 4.8
   -26.7 (-0.272, -3.87) | 2.1 to 2.5 lower than above value

   ■ CAUTION ■
   - Always calibrate the vacuum pump gauge when using it.
   - Never apply below ‐93.3 kPa (‐0.952 kg/cm2, ‐13.53 psi) or pressure over 101.3 kPa (1.033 kg/cm2, 14.69 psi).

Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace EVAP control system pressure sensor
