p2146 code
 

07 dodge 2500 with p2146 code truck still runs and pulls great anyone know what the code means??

Check the valve cover wiring harness. Probably that gasket connector. Could be a bad injector, but unlikely since it's running good.

the P2146 code is Fuel injector group A Supply voltage Circ/Open... have you had your valve cover off? injector work? set your valves? im almost positive group A is the front 3injectors check the plug its self clean with contact cleaner. and put A small amount of dielectric grease in the connector> clear the codes and see if that works. if not pull the valvecover and check all injector connections and wiring clearance from the rocker bridges...
