Re: The old pain, P0442
I DID IT!!!! I DID IT!!!
OK this is what has happened. The gas cap? NOPE, same problem and I am about $20 poorer but it was worth the try.
I scrapped the pipes leading to the fuel fill and painted them. Others I coated with Dow Corning 520......no help, light kept coming on after I reset it.
Today, I jacked the rear of the car, placed jack stands under it for safety and decided that I had to find SOMETHING that at least resembled a leak. I looked and looked to no avail. Next, I printed some diagrams from a Ford maintenance disc that I have for the car to learn where I could find the Canister Vent Solenoid. Talk about easy??? Like heck!
One bolt supporting the plastic shelf that holds the canister along with the canister vent solenoid BROKE and the other bolt I removed using my Sawzall. When I got this thing down, I said WOW!!!! I found the canister solenoid!!! It was a rusty mess. I removed it and took it to my workshop and chiseled the caked, scalling rust off the thing. I was stuck because today is Saturday and there was no place for me to purchase a replacement.
Anyway, after awhile, I got through the scalling rust and thought I might be able to seal the thing. So I painted the solenoid with water based polyurethane, the stuff for wood finishing. Dried the solenoid with my heat gun and repeated the procedure several times. I put poly over everything! I even dumped some into the connector to seal the pins.
Put everything back together, used tie wraps to hold the plastic shelf containing the canister and then moved onto my next project. That was flushing the radiator and the heater core with the car running.
I finished all the outstanding jobs and now had everything back together and went into the house to grab my laptop to reset the MIL light. Got into the car AND THE LIGHT WAS OUT!!! OUT!!! OUT!!!
With my luck it probably will come back on. but I am going to find out by driving the car. New solenoid??? I don't think so.....if my poly coating job holds out. But I do think I have the thing solved.
I hope my experience helps others who run into this very difficult OBD2 fault condition.
