SES

[Mikey]

Hey,
i have an intermittent Service engine light come on my 01, which I took to the shop to get read. it came out to be an EVAP error. My tank cap is on tight, any ideas of what would give me that issue, or where to start? Thanks!
Mikey :D
P.S. I did a search and didnt see many answers.

Read through here. There is a plastic hose that sometimes cracks and throws a SES code. If the hose is not cracked, get the purge valve checked or replaced. They are basically cheap at a dealer (about $20).

Since the picture doesn't show it anymore;

Look on the passenger side of the engine, right behind the TB there is a large vacuum line that comes out of the upper intake and runs behind the alternator. That is the line I am referring to.

also, even if your cap is tight, doesnt mean that the gasket inside it isnt damaged.

What was the code? Not all of the EVAP codes could be caused by a loose cap. Knowing the problem is somewhere in EVAP doesn't help. We need the actual code number to know what the problem is.

I have a similar problem...code P0440. The shop I took it to will get be getting a smoke machine soon to find out where exactly the leak is coming from. They initially thought it was just a loose gas cap and reset the code twice, but it kept reappearing.

thanks guys, I will get the code # checked again, but I will try checking that first. thanks
