Jeep is running well, no problems noted , no lights on that shouldn't be. But I hooked up a scan tool and got error message "P0004 Fuel Volume RegulatorControl Circuit High" This is under the Chrysler Transmission enhanced DTC (not sure why the fuel volume is under transminssion). My scan tool will not let me clear the code. Booked in for service next Monday as it has the extended warranty. It is an '06 Liberty with the AT. Any thoughts on this before I get to the dealer. I did an oil analysis last month and did find that the oil had some fuel dilution. Could this be the cause?

Has anyone had this problem at all?
