Evaporative Vapor Pressure Sensor: Testing and Inspection
EVAP CONTROL SYSTEM PRESSURE SENSOR
1. Remove EVAP control system pressure sensor with its harness connector connected.
CAUTION: Never apply force to the air hole protector of the sensor if equipped.
2. Remove hose from EVAP control system pressure sensor.
3. Install a vacuum pump to EVAP control system pressure sensor.
4. Turn ignition switch "ON" and check output voltage between ECM terminal 60 and ground under the following conditions.
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.
-
Discard any EVAP control system pressure sensor which has dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such a
concrete; use a new one.
5. If NG, replace EVAP control system pressure sensor.
