Without Tank Pressure Control Solenoid Vacuum (Tpc SV) Valve

Measuring Evaporative Emission (EVAP) Canister Purge Valve Resistance:

Inspecting Evaporative Emission (EVAP) Canister Purge Valve:

EVAPORATIVE EMISSION CANISTER PURGE INSPECTION

WARNING: Do not suck air through the Evaporative Emission (EVAP) canister purge valve tubes and hoses. Fuel vapor inside the EVAP canister purge valve is harmful.

TOOL REQUIRED
J 39200 Digital Multimeter

PROCEDURE
1. Disconnect the EVAP System canister purge valve electrical connector.
2. Using the J 39200, measure resistance of the EVAP canister purge valve between both terminals. If resistance is not 33 to 39 ohms at 20°C (68°F), replace the EVAP canister purge valve. Refer to EVAP Canister Purge Valve / Service and Repair. Service and Repair

If the resistance is within specification, proceed with Step 3.
3. Disconnect the EVAP canister purge valve vacuum hoses from the intake manifold and the vacuum pipe (from EVAP canister).
4. Blow into the EVAP canister purge valve vacuum hose that was disconnected from the vacuum pipe. Air should not pass through the EVAP canister purge valve and exit from the intake manifold hose.
5. Connect 12 volts DC to the EVAP canister purge valve terminals.
6. Blow into the EVAP canister purge valve vacuum hose that was disconnected from the vacuum pipe. Air should pass through the EVAP canister purge valve and exit from the intake manifold hose.
7. If the EVAP canister purge valve failed this inspection, replace it. Refer to EVAP Canister Purge Valve / Service and Repair. If the EVAP canister purge valve passed this inspection, reconnect the vacuum hoses and electrical connector.
