Evaporative Vapor Pressure Sensor: Testing and Inspection
Component Inspection
EVAP CONTROL SYSTEM PRESSURE SENSOR
1. Remove EVAP control system pressure sensor with its harness connector connected.
2. Remove hose from EVAP control system pressure sensor.
3. Turn ignition switch "ON".
4. Use pump to apply vacuum and pressure to EVAP control system pressure sensor as shown in figure.
5. Check input voltage between ECM terminal 62 (EVAP control system pressure sensor signal) and 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.
6. If NG, replace EVAP control system pressure sensor.
CAUTION:
-
Never apply force to the air hole protector of the sensor if equipped.
-
Discard any EVAP control system pressure sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such
as a concrete floor; use a new one.
