Oh, the dreaded Check Engine Light! There is nothing worse that can happen to my wife’s car than a big bright Check Engine Light! That thing comes on and it’s time to buy a new car. Since I do not like car payments I don’t really think that is a viable option, check out this post to learn why! This needs to be fixed right away!
However, I found that this points directly to the High Pressure Purge Valve. In my case I tested the valve and with my first test found it to be faulty. The test I performed was to blow straight through it, if you can feel air on the other side, it is faulty. The default state is closed so you should not be able to blow air through it.
After pulling out the High Pressure Purge Valve, you can start testing it. Blow through the valve and see if air goes through. If it does, the valve is stuck open and will need to be replaced. At this point, I knew what my problem was, but if you don’t get air through, there is another test you can run. You can supply power to the electrical connector to see if the valve opens. I did not have to do this, but just supply a ground and a 12V source to see if it opens. If it does not, it is faulty and will need to be replaced. If it does open, your problem most likely lies elsewhere.
Replacement is the exact opposite of the removal. You just push the High Pressure Purge Valve
into the side of the intake manifold, tighten up the bolt, and reattach the
hose and electrical connector.
