EVAP Purge Valve Problem

Hi. Does anyone know where I can find the EVAP Purge Valve on my 1996 (Plastic body) Trans Sport with the 3.4l engine?

I have the Haynes Manuals for the older 1991 style body and the newer metal bodied one (for info on the 3.4l engine). On my vehicle, the EVAP canister is behind the passenger side headlight (as on the 1991 vehicle) which is different to the newer model. According to the new model's manual this is located near the fuel tank and the purge valve is below the ignition coils at the rear of the engine. I cannot see into this area but cannot feel anything like a valve there. There is a small valve with two pipes and a cable going to it mounted on the passenger side inner wing (fender). Is this the purge valve?

Bill:
Not having worked on a 3.4, I cannot direct you exactly to where it is; however, I do not believe that is the solenoid you are looking for.
Interestingly, both your 96 3.4 and my 95 3.8 use the identical solenoid http://www.rockauto.com/en/moreinfo....261796&jsn=397
On the 3.8 it is mounted on a bracket on the engine, at the rear, close to the throttle body. Yours however will probably be mounted differently.
It is fed front a small diameter hard plastic line from the canister, via a quick disconnect around serpentine belt. From there it snakes around the back on my engine to the solenoid, which is mounted up top in plain sight. From there the output hose eventually goes to the throttle body.
It is controlled by the pcm; the 95 manual breaks it out as a green with white stripe wire, and a pink wire. I think yours will be the same
Good luck
Jeff

Re: EVAP Purge Valve Problem

Hi Sergei. Thanks for the photos. I have just been out to look at my car with them. Unfortunately, although I can see the other valves etc in the photos, the purge valve is not there. I have traced the plastic tubing as best I can and I think it is below and behind the ignition coils as described in the new model's manual. It is impossible to see or get to the valve without pulling the engine forward. I could only just touch it by reaching over the engine, so I'm not certain that it is actually the correct valve.

Re: EVAP Purge Valve Problem

Hi Sergei. It looks as if that is my engine, although the pipe from the Evap cylinder is routed over the drive belt end of the engine. What a crazy place to mount the valve. It is virtually impossible to change it without incurring huge garage costs. As the fault code is intermittent at the moment, I think I may just ignore it. I don't think it is a serious problem.

...and the ignition coils....! WIth the 3.8 they were right in front. However with the 3.4 being a 60 engine (3.8 was 90) maybe there is more room between the back of the engine and the firewall....
