CEL - evap sensor - repeatedly - common issue?
Wondering if this is a common thing. We bought our 04 brand new in April of 04. Paid it off last spring and never had a single issue up until then. Then, this summer, while on vacation, the CEL comes on so I go straight to an auto parts store and get it checked. It's an evap sensor related code and is commonly caused by leaving the gas cap on too loose or a bad o-ring in the gas cap, according to a mechanic that just happened to be in the auto-zone store when I found out what they CEL issue was. My wife and are both familiar with this scenario from past experiences with another vehicle so we are both always conscious of tightening the gas cap everytime we fill up. However, we went with it and cleared the CEL and had no immediate recurrence.
Several times since the initial incident we've had the CEL come on with the same code and sometimes, after driving home and shutting it down, the CEL is no longer on when we crank it back up. Other times, the CEL stays on for days or until we go have it scanned and get it reset. So, I finally take it to the dealer and spend a day and a half and a couple hundred bucks gettting it tested and, supposedly, fixed (something was replaced, not sure what other than it was not the gas cap). However, twice since taking it to the dealer the CEL has come on again and again both times the evap sensor code. It seems to run and be running fine and the auto parts people and the dealer says it's not something that's harmful to drive even with the CEL on with that code. So, we do.
Anyone else experience this and/or have any suggestions? My next logical step would seem to be to take it back to the dealer that did the work, with the CEL on again, and demand that it be fixed. But, that could go back and forth forever.
