Hello. I recently acquired a well maintained 2012 Ram 1500 (5.7 Hemi) (91K) - a new type of vehicle for myself. Today I noticed a MIL light. Auto Zone checked and came back with a P 0456 code. I replaced the gascap. But reader was unkowledgeable on how to erase the code. Note: I haven't tried the battery (negative disconnect). This summer, I had driven the vehicle about 800 miles, no issues, starts ok, idles ok, accelerates ok , no vibrations, highway: 18-19 mpg; city 14-15. Yesterday, a winter tire changeover, a 120 mile trip, I filled the tank enroute - no light. Today in the city : the MIL. Also , the light that advises ECN doesn't illuminate, the avg gas mileage (numeric) readout is not consistent, however, (the seem to indicate the correct fuel flow per the appropriate condition). I have been reading previous posts and understand that the there could be numerous issues with in the evaporative system and it seems that the best method to troubleshoot is via a smoke test. My OBD is in another car miles away.
Before throwing parts at it via a shop, I wanted to ask if this type of Code can be reset via a battery disconnect and if not, can that only be done with a Dodge shop tool? Any comments will be appreciated.
