I have 1997 Mercury Tracer LS with 123000 miles on it. The check engine light is on and getting code P1443. According to Advance Auto and Autozone it is " Evaporative emission control system control valve", what ever that means. The guy at Advance suggested changing the wiring harass, does this sound right? What do I need to do to get this problem fixed?

P1443 Evaporative emission control system, vacuum system, purge Control Solenoid or purge control valve fault. I am notot sure where it is on your car, but the equipment to test it is about $1,300.00 U.S! They check these with a smoke pump to test for leaks in the system. Most of these valves are on the firewall and have a vacuum hose attached. They also have what looks like a tire valve with a green cap. Will be cheaper to replace it than to test it! I think they are about $100.00 if you can find one.

You are close, it is the evaporative control system purge valve malfunction, it means the purge valve is bad, you do not need a harness. That is funny, that is all you need. It is on the drivers side of the engine compartment. I would send you a diagram but you would not be able to see it.

Did this come on since you last filled your fuel tank?

I called a Ford Dealership this morning and gave them the code. They said there was definitely a leak somewhere in the emissions system. They said a smoke test on emissons needed to be performed. And that it was probably the canister purge valve or the hose leading to the intake leaking. I am having a place do the smoke test for $30.00 tomorrow. Then I will replace the part or parts that leak. Thanks so much for the help again, much appreciated.

No doubt that is super inexpensive, we get 1.5 hrs for it $140.00. But that does include lemon or orange flavor.

I have not had the smoke test performed yet. My husband replaced the hose going into intake today and another place leak was occurring. Waiting to see if service engine soon light comes back on. I had two major leaks where the clamp was not holding near as good as it needed to be.
