EVAP Tank Pressure Control Solenoid Valve Inspection

EVAP 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 (2) with the DMM (1). The resistance should be 28 to 36 ohms at 20°C (68°F).
3. Replace the EVAP tank pressure control solenoid valve if the resistance is not 28 to 36 ohms at 20°C (68°F). Proceed to step 3 if the resistance is within the specification. Refer to EVAP Tank Pressure Control Solenoid Valve Replace Replacement.
4. Disconnect the EVAP tank pressure control solenoid valve vacuum hoses from the intake manifold and from the Tank Pressure Control valve vacuum pipe.




5. Blow air into the EVAP tank pressure control solenoid valve vacuum hose that was disconnected from the vacuum pipe. Air should not pass through the EVAP tank pressure control solenoid valve and exit from the intake manifold hose.




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 vacuum hose that was disconnected from the vacuum pipe. Air should pass through the EVAP tank pressure control solenoid valve and exit from the intake manifold hose.
8. Replace the EVAP tank pressure control solenoid valve if the EVAP tank pressure control solenoid valve failed this inspection. Refer to EVAP Tank Pressure Control Solenoid Valve Replace Replacement.
9. Reconnect the EVAP tank pressure control solenoid valve vacuum hoses.
10. Reconnect the EVAP tank pressure control solenoid valve electrical connector.
