In a nutshell that is a rear fuel trim lean code.......
That is a 2 trip fault code (meaning the vehicle has to be driven twice under the corrrect conditions to set)
Three passing trips will turn the light off by itself but code will be stored........

I had a Chrysler vehicle not long ago with that code that drove me crazy. The first think to look at is the downstream O/2 sensor itself. If the sensor is not the problem, then the exhaust system has to be examined very closely. Chrysler has an internal memo about cracks in the catalytic converter that causes this code. They tend to split right along the seam weld but you have to look very closely and possible pressurize the exhaust system to find it.

thanks for the replies, where would the downstream o2 sensor be located. also now that the check engine light went off could this have been just a hiccup, or is there a problem.
thanks again guys

There are no such things as hiccups in computer systems. The problem occurred at one time and will likely occur again.
The sensor in question here is marked #4 in the pic.
