Tank Pressure Control Solenoid Valve Inspection

Tools Required
J 39200 Digital Multimeter
1. Disconnect the EVAP tank pressure control solenoid valve electrical connector.
2. Measure the resistance between the electrical terminals of the EVAP tank pressure control solenoid valve with the DMM. The resistance should be 30 to 34 ohms at 20°C (68°F).
3. Replace the EVAP tank pressure control solenoid valve if the resistance is not 30 to 34 ohms at 20°C (68°F). Proceed to step 3 if the resistance is within the specification.
4. Disconnect the EVAP tank pressure control solenoid valve vacuum hoses.
5. Blow air into the EVAP tank pressure control solenoid valve port (3). Air should not pass through the EVAP tank pressure control solenoid vacuum valve (2) and exit from port (1).
6. Connect 12 volts DC to the EVAP tank pressure control solenoid valve electrical terminals.
7. Blow air into the EVAP tank pressure control solenoid valve port (3). Air should pass through the EVAP tank pressure control solenoid vacuum valve (2) and exit from port (1).
8. Replace the EVAP tank pressure control solenoid valve if the EVAP tank pressure control solenoid valve failed this inspection.
9. Reconnect the EVAP tank pressure control solenoid valve vacuum hoses.
10. Reconnect the EVAP tank pressure control solenoid valve electrical connector.
