Replace the EVAP vent valve (canister close valve) to resolve evaporative emission system faults or check engine lights related to the purge system.
Warnings
⚠The EVAP system operates under vacuum pressure. Do not smoke or work near open flames.
ℹ️Perform this procedure with the engine cold and vehicle parked on a level surface.

Preparation
- Park vehicle on level ground and apply parking brake
- Place wheel chocks behind front wheels
- Turn ignition to OFF position and remove key
- Allow engine to cool completely if recently driven
Procedure
- 1Raise and secure rear of vehiclePosition jack under rear jacking point on driver side. Raise vehicle and support with jack stands positioned at factory lift points. Ensure vehicle is stable before working underneath.
- 2Locate EVAP vent valveThe EVAP vent valve is mounted on the charcoal canister assembly, located near the fuel tank on the driver side rear underneath the vehicle. Identify the valve with electrical connector and two hose connections.
- 3Disconnect electrical connectorPress the locking tab on the electrical connector and pull straight away from the vent valve. Avoid pulling on the wires themselves.
- 4Disconnect vapor hosesRelease the hose clamps on both vapor hoses connected to the vent valve using a flathead screwdriver. Carefully twist and pull the hoses off the valve ports. Note the orientation and routing of each hose for reinstallation.ℹ️Some fuel vapor odor may be present when disconnecting hoses. This is normal.
- 5Remove vent valve mountingRemove the mounting bolt securing the EVAP vent valve to the canister bracket using a 10mm socket. Remove the valve from the vehicle.
- 6Install new vent valvePosition the new EVAP vent valve onto the mounting bracket in the same orientation as the original. Install the mounting bolt and torque to specification.
- 7Reconnect vapor hosesPush each vapor hose firmly onto the correct port of the new vent valve until fully seated. Reinstall the hose clamps and torque to specification, ensuring clamps are positioned over the hose barbs.Torque specHose Clamps3 Nm (2 lb-ft)
- 8Reconnect electrical connectorPush the electrical connector onto the new vent valve until it clicks into place. Verify the locking tab is fully engaged.
- 9Lower vehicleRemove jack stands and carefully lower the vehicle to the ground. Remove wheel chocks.
Reassembly
- Verify all hose connections are secure and properly routed
- Ensure electrical connector is fully seated and locked
Verification
- Turn ignition to ON position without starting engine and verify no fuel odors are present
- Start engine and check for proper idle with no rough running
- Use an OBD-II scanner to clear any stored EVAP codes
- Drive vehicle through a complete drive cycle to allow the ECM to test the EVAP system
- After 50-100 miles of driving, verify that EVAP-related codes do not return
