Code 1494: Evap System Leak
- Thread starter Zman
- Start date
1491 would be a code for a Cherokee with electric fan motor Tj have a mechanical driven fan so no fan really Don’t know why you would have that code
Yes,
If not fan, then might be the elusive evap system malfunction which will have me starting with egr valve I think
Interesting, because 1491 only comes up on Google as an electric fan issue with a Cherokee. I've never heard of this code before until now.
It may be worth clearing with the scanner to see if it comes back.
Ahhh, usually that code ends up being resolved by replacing the gas cap with an OE gas cap, or making sure it's on tight.
Actually, @Jerry Bransford had some recommendations for gas cap replacements, but I can't seem to find them. Maybe he'll chime in.

Chris, is there a way to edit the subject line in my post? Or should I repost as new, showing 1494 instead of 1491 in subject line ?
Yes. Sometimes with these codes it's worth clearing them just to see if they come back. Mine did it once, I cleared it, and it never came back.
Yup,
This one I’ve cleared many times in the last month or so....
She has been out for service lately and I am now just starting to troubleshoot the code as I did not want to pay my mechanic until I had a go at it.
Two videos that may be of help when troubleshooting this:
And this:
While those aren't Jeeps, it's the same procedure. A smoke machine definitely makes it easy as can be to find an evaporation system leak!
