1.

CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR

1. Turn ignition switch OFF.

2. Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.

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 and ground under the

following conditions.

CAUTION:

• Always calibrate the vacuum pump gauge when using it.
• Do not apply below -93.3 kPa (-0.952 kg/cm

2

, -13.53 psi) or pressure over 101.3 kPa (1.033 kg/

cm
