Preparation

Park vehicle on level ground and engage parking brake
Allow engine to cool completely
Open hood and secure with prop rod
Locate the EVAP purge valve on the driver side of the engine, mounted on the intake manifold near the firewall

Procedure

1
Disconnect electrical connector
Press the tab on the electrical connector attached to the EVAP purge valve and pull straight away from the valve to disconnect. If connector is difficult to access, you may need to route your hand from below the valve assembly.
2
Disconnect EVAP hose from purge valve inlet
Locate the EVAP hose connected to the inlet side (bottom port) of the purge valve. Press the quick-connect release tabs together and pull the hose straight off the valve. The hose runs from the EVAP canister and may have a slight fuel vapor odor.
3
Disconnect EVAP hose from purge valve outlet
Locate the EVAP hose connected to the outlet side (top port) of the purge valve. This hose connects to the intake manifold. Press the quick-connect release tabs together and pull the hose straight off the valve. If tabs are difficult to access, use a flathead screwdriver or pick to depress the locking tabs while pulling.
4
Remove purge valve mounting bracket bolt
Using a 10mm socket with extension, remove the single bolt securing the purge valve mounting bracket to the intake manifold. The valve is mounted in a plastic bracket that is bolted to the manifold.
Torque spec
Mounting Bolts34 Nm (25 lb-ft)
5
Remove purge valve from bracket
Pull the purge valve upward out of the mounting bracket. The valve slides into the bracket and should remove easily once the mounting bolt is removed. Remove the bracket if it needs replacement or if easier access is needed.
6
Install new purge valve into bracket
Insert the new EVAP purge valve into the mounting bracket, ensuring it seats fully. The valve should slide in with the electrical connector facing outward for easy access. If bracket was removed, position it back on the intake manifold.
7
Install mounting bracket bolt
Thread the mounting bracket bolt by hand first to ensure proper thread engagement. Tighten the bolt to specification using a 10mm socket and torque wrench.

8
Reconnect EVAP hoses
Push the outlet EVAP hose (to intake manifold) onto the top port of the purge valve until it clicks into place. Push the inlet EVAP hose (from canister) onto the bottom port until it clicks. Verify both connections by gently pulling on each hose to confirm they are locked.
9
Reconnect electrical connector
Push the electrical connector onto the purge valve until it clicks into place. Ensure the locking tab is fully engaged. Gently tug on the connector to verify it is secure.

Reassembly

Verify all hose connections are secure and fully seated with locking tabs engaged
Ensure electrical connector is fully locked in place
Check that no tools or parts were left in the engine bay

Verification

Start the engine and allow it to idle. Listen for any unusual hissing sounds that could indicate a vacuum leak at the purge valve connections
With engine running, verify no Check Engine Light is present on the instrument cluster
If available, use a scan tool to command the EVAP purge valve on and off while engine is running to verify proper operation (you should hear a clicking sound from the solenoid)
Check for proper EVAP system operation by monitoring freeze frame data or performing an EVAP system test with a scan tool
Take vehicle for a short test drive and verify no EVAP-related diagnostic trouble codes set (P0441, P0443, P0446, etc.)
