The reson I'm asking is because mine had this code this past saturday driving on the interstate and it never acted up once. It has gone 600+ miles since then and the lights gone with no hiccup. 6800 miles on it. Went to the dealer Tuesday after the light went away and they told me they are having issues with the rams mostly. But couldn't help me with no light being on.
Sorry for the hijack of the thread, hope your issues are resolved.
Light only came on once at 10,600 miles shortly after getting on the highway. The light has no effect on performance. Took it to the dealer and they said it needed an ECM flash (This is the same flash that others talk about solving a bunch of different MILs, pretty large spread of issues). However, at the bottom of the TSB for that flash, it says that if the car already had the P20EE code then additional repair is necessary.
Dealer misunderstood I guess, even though I pointed it out, and said that they drove it and the light didn't come back on "so it was fixed for now."
I got home and scanned the car, and it already had the P20EE code pending (dealer is full of it that they can't see pending codes) and it had already failed the catalyst readiness test.
400 miles later, light comes back on, same code P20EE. Now it's been at the dealer for a week while they wait for the updated cat.
Hope that paints a better picture for you.
