2003 Jeep Liberty Emissions
My engine warning light is on. The computer code says it is an emissions leak. Where would be a good place to start looking for the leak? Most likely cause? Could it just be sensor failure?

do you mean evap leak? yes it could be a sensor regaurdless, first and easiest thing to check is your gas cap make sure its tight. that will cause an engine light. check that and get back to me

It might be evap, im not sure. Its been about 3 months. It hasnt affected performance any though. I will go get the code again tomorrow.

check your gas cap, and look in the left hand corner of your engine compartment for any hoses, cracks in hoses or disconnected hoses. gas cap has to be on tight. or you wil get an engine light. but look for them hoses. do you smell gas?
