I have a 2001 Jeep Cherokee, with the inline 6.
A couple weeks ago I posted a thread 2001 Jeep Cherokee Timing
. Per cmesadoin
's response, he was absolutely correct by saying that there could be many things associated with my loss of fuel mileage.
As I am now finding out, because I think I was way off by labeling my thread timing.
Anyways, to get to the point. My check engine light finaly went off again. And this time two error codes were triggered. P0442 and P0455. Small EVAP leak and Large EVAP leak respectively. I also began to notice the smell of gas fumes. Typically only in the morning when I first start the vehicle and begin my drive(I live in south texas).
Courtesy of ALLDATA, I have the Diagnostic Test Procedures to narrow down the root cause of my problem. I've checked the simpler causes, but at the moment, I am unsure wether I can get a hold of a Evaporative Emission Leak Detector (EELD). I was wondering if there was a simpler method? Or if this problem is typically caused by one component over another?
