My problem was evap purge solenoid I would get quad driver fault code. This just means 1 of the 4 or more are bad. Using a vacuum pump should be able to find the culprit. After buying one of these junk pumps I found out they rent them to you at autozone for cheap. I fixed mine by getting an acdelco solenoid put on it all my lights stopped. Mine allows flow during like freeway. Otherwise it closed when parked in driveway. So there should be no flow between solenoid acts like a valve and it energized by pcm during non idle events. It like a check valve between engine purge canister and fuel tank. Store gas is sent to intake when purge solenoid energizes and opens a path between the purge canister and intake manifold Just follow the hose from the solenoid where it goes after the throttle body.

Great video guys, yeah I know how those dealers are! I once had 2 new 2007 chevy 3500 plow trucks that would overheat in the plowing season, the dealer service rep. said we should take the plows off and carry them in the beds between parks, I checked with some guys on a site called BAT Auto and one guy sent me a service bulletin for the exact problem which gave me a list of parts needed which was a new fan clutch that took care of the problem, which was under warranty, now why couldn't the G. M dealer do this? never trusted them again after that. I gave all of this information to the plow installer who said he had people complaining of the same problem and boy was he ever happy.

Remember viewers, If WE can do it, you can do it! Thanks for watching.
Great Collaboration Video! So like Ivan said, a vent solenoid caused the PCM driver for that solenoid to fail?
Only saw that once on a 84 or 85 GMC V8 G van. It was an open diode on an air conditioner clutch. The AC worked, then turned off the clutch and poof went the driver in the PCM. Also set the timing back to base timing. They drove it over 100 miles like that, almost smoked the cat! I'd had some training on the system, knew exactly what was wrong. Another PCM, new diode, checked base timing and advanced timing with the A/C on. Fixed and down the road!

last year my 2010 escape got a recall for a reason that could cause fumes in the car and they had to take out my back seats to get at something. now i wasn't having problems with the fumes before the fix but i have been ever since. the ford tech said i might be able to smell gas for a little bit then it would go away but it's been a year now, i really don't want to take it back to them because they seem to create problems and not fix any, any input at what i should look at? i should add i only smell fumes when i fill it past 3/4 of a tank, anything below that is fine.

I hate my ford p0446. I still cant fill up gas after purge, vent solenoid replace. Ran smoke test. Nothing. Circuit is fine and duty cycles properly.
Fuel pressure sensor is fine.
But there's a tank vent valve that may be restricted causing excessive tank vapor fuel spit up etc.
Our lovely friends at Ford discontinued my tank.
The fuel tank vent valve is non serviceable plastic welded to the composite tank.
Thinking of cutting out vent valve and drilling out orifice then epoxy it back in.
Eric and community I need your opinion. Thanks

Hey Guys. Thanks for the video. I have this same exact problem on my 2008 Ford Escape 3. 0 AWD (Engine fault code and gas filling problem. I replaced the EVAP vent as well and it did not correct the problem. I don't have the nice diagnostic equipment you guys have but I used my multimeter to check the voltage being sent by the computer and I do have 12V going to the EVAP vent. Is there any other thing that can cause this problem besides the computer or the EVAP vent? Any help would be much appreciated.

This is a great video Eric and Ivan! Thanks for sharing this with us. I have seen this one, but I had a P0446 today and wanted to watch some other videos to see what I maybe failed on in my video!
Nevertheless, you guys are great techs for sharing your knowledge and experience with all of us!
Have a great 4th with the family guy's!

Interesting subject. I ran across a Lincoln LS ABS module that turned on the ABS light. The system works however. That part is 1, 100 from Ford and they confirmed it had a P code that suggested power brake module boost something. Some have said it's just a cracked solder joint inside and those can be repaired but have to be re-programmed.

So guys I pulled my EGR out and cleaned it real good, do the Engine check light with 2 codes p0401 and the other for the bad thermostat which I replace. Now after putting it all back together with a new a new vacuum line, that had some dry rot I have a new code P0443. Did I pump something, or loose a connection? help. great video
