EVAP Canister Purge Valve Inspection

1. Disconnect the electrical connector from the EVAP canister purge valve.
2. Measure the resistance between the electrical terminals of the EVAP canister purge valve (2) with the DMM (1). The resistance should be between 30-34 ohms at 20°C (68°F).
3. Replace the EVAP canister purge valve if the resistance is not between 30-34 ohms at 20°C (68°F). Proceed to step 4 if the resistance is within the specification.




4. Disconnect the vacuum hose (1) of the EVAP canister purge valve from the intake manifold pipe.
5. Disconnect the vacuum hose (2) from the EVAP canister purge pipe.
6. Blow air into the vacuum hose (2) that was disconnected from the EVAP canister purge pipe. Air should not pass through the EVAP canister purge valve (3) and exit from the intake manifold hose (1).




7. Connect 12 volts DC to the electrical terminals of the EVAP canister purge valve.
8. Blow air into the vacuum hose (2) that was disconnected from the EVAP canister purge pipe. Air should pass through the EVAP canister purge valve and exit from the intake manifold hose (1).
9. Replace the EVAP canister purge valve if the EVAP canister purge valve failed this inspection.
10. Connect the vacuum hoses to the EVAP canister purge valve.
11. Connect the electrical connector to the EVAP canister purge valve.
