Procedure

1
Locate the EVAP purge valve
The EVAP purge valve is located on the driver's side of the engine bay, mounted on a bracket near the intake manifold. It is a black cylindrical component with an electrical connector and two vacuum hoses attached.
2
Disconnect electrical connector
Press the locking tab on the electrical connector and pull it straight off the purge valve. Do not pull on the wires themselves.
3
Disconnect vacuum hoses
Using needle-nose pliers or by hand, squeeze the hose clamp tabs and slide them back away from the valve connections. Remove both vacuum hoses from the purge valve ports, noting their positions. The upper hose connects to the intake manifold and the lower hose connects to the charcoal canister.

Reassembly

Verify all connections are secure and hose clamps are properly positioned
Ensure no tools or shop towels were left in the engine bay

Verification

Start the engine and listen for vacuum leaks or unusual hissing sounds near the purge valve
Allow engine to reach operating temperature and verify no check engine light appears
Use an OBD-II scanner to check for EVAP system codes (P0441, P0443, P0455) and verify none are present
Perform a test drive and confirm smooth idle and acceleration with no hesitation
