This procedure replaces the EVAP canister vent valve, which controls the venting of the fuel vapor canister as part of the evaporative emissions control system.

Tools required

Parts

• EVAP canister vent valve × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and apply parking brake
2. Place wheel chocks in front of the front wheels
3. Raise the rear of the vehicle and support with jack stands at the frame rails
4. Remove the driver side rear wheel for improved access
5. Turn ignition to OFF position and remove key

Procedure

1. 1

   Access the EVAP canister area
   Locate the EVAP canister assembly on the driver side frame rail ahead of the rear axle. The vent valve is typically mounted to the canister or on a bracket nearby. You may need to remove the rear inner fender liner or splash shield for better access. Use trim panel tools to carefully release any push clips securing the liner.
2. 2

   Disconnect electrical connector
   Locate the electrical connector on the EVAP vent valve. Press the locking tab and pull the connector straight off the valve. If the connector is difficult to remove due to corrosion or dirt, gently wiggle while pulling. Do not pull on the wires themselves.
3. 3

   Disconnect vapor hoses
   Identify the two vapor hoses connected to the vent valve - one from the canister and one vent line to atmosphere. These typically use quick-disconnect fittings. Press the release tabs on each fitting and pull the hoses straight off the valve ports. Note the orientation and position of each hose for reinstallation.
4. 4

   Remove vent valve mounting
   Remove the mounting bolt(s) securing the vent valve to the canister or mounting bracket using a 10mm socket. The valve may be secured with one or two bolts depending on the specific configuration. Keep the mounting hardware for reinstallation or replacement.

5. 5

   Remove old vent valve
   Pull the vent valve away from its mounting location. Inspect the mounting bracket and surrounding area for any damage, corrosion, or debris. Clean the mounting surface if necessary.
6. 6

   Install new vent valve
   Position the new EVAP vent valve into the mounting bracket, ensuring it is oriented the same way as the original valve. The valve should sit flush against the mounting surface. Start the mounting bolt(s) by hand to ensure proper thread engagement.
7. 7

   Torque mounting bolts
   Using a torque wrench, tighten the vent valve mounting bolt(s) to 34.0 Nm (25.0 lb-ft). Do not overtighten as this can crack the valve housing.

8. 8

   Reconnect vapor hoses
   Push each vapor hose fitting firmly onto the corresponding port on the new vent valve until you hear or feel a distinct click indicating the fitting is locked. Gently tug on each hose to verify it is securely connected. Ensure the vent to atmosphere line is pointing downward and not kinked.
9. 9

   Reconnect electrical connector
   Push the electrical connector onto the vent valve until the locking tab clicks into place. Verify the connection is secure by gently pulling on the connector body.
10. 10

    Reinstall access panels
    Reinstall any inner fender liner or splash shield components that were removed. Ensure all push clips or fasteners are properly seated. Install the rear wheel and torque lug nuts to specification (per vehicle owner's manual).

Reassembly

1. Lower the vehicle from jack stands and remove wheel chocks
2. Verify all connections are secure and no tools or parts were left in the work area
3. Check that the vent valve electrical connector is fully engaged

Verification

• Start the engine and verify no check engine light is present
• Use an OBD-II scanner to check for any EVAP-related diagnostic trouble codes
• Perform an EVAP system self-test using a scan tool if available, or drive the vehicle through a complete drive cycle to allow the system to self-test
• Visually inspect the vent valve area for any fuel vapor odors or visible leaks
• Verify the vent valve is operating by listening for a clicking sound when the ignition is cycled (valve performs a self-test)
