This procedure covers the replacement of the EVAP canister vent valve, which controls the venting of the evaporative emissions system to atmosphere during fuel system purging.

Warnings

Tools required

Parts

• EVAP Canister Vent Valve × 1 — Use OEM specification
• Mounting grommet (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Allow engine and exhaust system to cool completely
3. Gather all tools and replacement parts

Procedure

1. 1

   Access the rear underside
   Position yourself to access the left rear area of the vehicle near the fuel tank. The EVAP vent valve is mounted on or near the charcoal canister assembly on the driver's side of the fuel tank. You may need to use a work light for visibility.
2. 2

   Locate the EVAP vent valve
   Identify the EVAP canister vent valve. It is a small solenoid valve with an electrical connector and two hoses attached - one from the canister and one venting to atmosphere through a filter. The valve is typically mounted to a bracket with a single bolt or integrated into the canister assembly.
3. 3

   Disconnect electrical connector
   Press the locking tab on the electrical connector and pull straight off the vent valve. Do not pull on the wiring harness itself. Note the orientation of the connector for reassembly.
4. 4

   Disconnect vent hoses
   Carefully disconnect the two EVAP hoses from the vent valve. These may be secured with push-on fittings or small hose clamps. If hose clamps are present, loosen them using a flathead screwdriver or appropriate socket. Note the orientation of each hose for proper reconnection.

5. 5

   Remove mounting hardware
   Remove the mounting bolt securing the vent valve to its bracket using a 10mm socket. If the valve is integrated into the canister assembly, it may twist-lock or have a different mounting method. Keep the mounting hardware for reinstallation.

   Mounting Bolts27 Nm (20 lb-ft)
6. 6

   Remove old vent valve
   Pull the vent valve from its mounting location. Inspect the mounting grommet or bracket for damage or deterioration. If the grommet is cracked or torn, replace it with the new valve.
7. 7

   Install new vent valve
   Position the new EVAP vent valve into the mounting bracket or location, ensuring any grommets are properly seated. Verify the valve is oriented correctly with hose ports accessible.
8. 8

   Secure mounting hardware
   Install the mounting bolt and tighten to specification using a torque wrench. Ensure the valve is firmly mounted and does not rotate or move excessively.

9. 9

   Reconnect vent hoses
   Connect the two EVAP hoses to the correct ports on the new vent valve. Ensure push-on fittings are fully seated with an audible click. If hose clamps are used, position them properly and tighten to specification.

10. 10

    Reconnect electrical connector
    Push the electrical connector onto the vent valve until it clicks into place. Gently tug on the connector to verify it is fully locked. Ensure no wiring is pinched or under tension.

Reassembly

1. Verify all hose connections are secure and properly routed without kinks
2. Ensure electrical connector is fully locked and wiring is not in contact with hot exhaust components
3. Double-check that mounting bolt is torqued to specification

Verification

• Start the engine and allow it to idle for 2-3 minutes, listening for any vacuum leaks or unusual sounds from the EVAP system
• Use an OBD-II scanner to clear any existing EVAP codes and verify no new codes appear
• Perform a test drive and monitor for check engine light illumination
• After 1-2 drive cycles, verify the EVAP system readiness monitor completes without setting codes
• Visually inspect under the vehicle to confirm no hoses have disconnected and the valve remains securely mounted
