EVAP Control System Pressure Sensor

Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.
Always replace "O" ring with a new one .

CAUTION:

Always calibrate the vacuum pump gauge when using it.
Do not apply below -93.3 kPa (-700 mmHg, -27.56 inHg) or pressure over 101.3 kPa (760 mmHg, 29.92 inHg).

Install a vacuum pump to EVAP control system pressure sensor.
Turn ignition switch ON and check output voltage between ECM terminal 32 and ground under the following conditions.
