Tools required

Parts

• EVAP vent valve (canister vent solenoid) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn ignition to OFF position and remove key
3. Allow engine to cool if recently driven
4. Gather all tools and replacement parts

Procedure

1. 1

   Locate the EVAP vent valve
   The EVAP vent valve is mounted on or near the charcoal canister assembly, located underneath the vehicle on the driver's side, forward of the rear wheel. Lie down or use a creeper to access the area behind the fuel tank.
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 access, you may need to reach from different angles or use needle-nose pliers to depress the tab.
3. 3

   Disconnect vapor hoses
   The vent valve has two vapor hoses connected. Identify the quick-connect fittings or hose clamps. For quick-connect fittings, press the release tabs and pull the hose straight off. For clamped hoses, use pliers to squeeze and slide the clamp away from the valve, then twist and pull the hose off. Note the orientation and routing of hoses for reinstallation.
4. 4

   Remove mounting hardware
   The EVAP vent valve is typically secured with a single mounting bolt or bracket. Use a 10mm socket to remove the mounting bolt. Support the valve as you remove the final fastener to prevent it from falling.

5. 5

   Remove EVAP vent valve
   Carefully maneuver the valve out of its mounting location, ensuring all hoses and electrical connections are fully disconnected. Inspect the valve and surrounding area for any debris or contamination.
6. 6

   Inspect hoses and connections
   Examine the vapor hoses for cracks, damage, or deterioration. Check quick-connect fittings for damage. Inspect the mounting bracket for rust or damage. Replace any damaged components as necessary.
7. 7

   Install new EVAP vent valve
   Position the new vent valve in the mounting location, ensuring it is oriented correctly with the electrical connector accessible and hose ports aligned with the vapor lines. Insert the mounting bolt and hand-tighten.

   Tighten mounting hardware
   Using a 10mm socket and torque wrench, tighten the mounting bolt to 27.0 Nm (20.0 lb-ft). Ensure the valve is securely mounted and does not move.

9. 9

   Reconnect vapor hoses
   Attach the vapor hoses to the vent valve in their original positions. For quick-connect fittings, push the hose straight onto the valve until you hear or feel a click. For clamped hoses, push the hose onto the valve port fully, then slide the clamp into position over the connection point and ensure it is properly seated.

    Reconnect electrical connector
    Push the electrical connector straight onto the EVAP vent valve until the locking tab clicks into place. Gently tug on the connector to verify it is securely locked.

Reassembly

1. Double-check all hose connections are secure and properly routed
2. Verify electrical connector is fully seated and locked
3. Ensure no tools or parts are left under the vehicle

Verification

• Start the engine and allow it to idle. Listen for any abnormal hissing or vacuum leak sounds from the EVAP system area
• Check for diagnostic trouble codes using an OBD-II scanner. Clear any existing EVAP codes if replacement was performed to address a fault
• Perform a test drive and monitor for Check Engine Light illumination
• If available, use a scan tool to command the EVAP vent valve open and closed to verify proper operation
• Verify no fuel vapor odors are present around the vehicle after operation
