Purge Valve Replacement
How are purge valve issues diagnosed?
A faulty canister purge valve is usually diagnosed from a fault code stored when the check engine light turns on. The valve will be checked to make sure it's able to open and close correctly. If it's working, the part that controls the valve will also be checked.
How is a canister purge valve replaced?
The valve's location depends on the make and model of the car. Any items blocking access to it will need to be removed. The valve is then disconnected from its mount, hoses disconnected, and the new valve is installed. Any hoses or other related parts should be inspected and replaced or repaired as necessary.
Can I replace the canister purge valve myself?
It largely depends on where the valve is located in your car. If it's easy to access, and you have the tools and knowledge to do the job, it's a fairly straightforward job. Otherwise, let a certified mechanic handle this repair.
