Here is some PD info on P2149:
Case Number K30540141
Vehicle Issue MIL and the engine runs rough. P2146 or P2149 are logged.;No wiring problems such as a chafed or shorted wire are found per P2146 / P2149 diagnostics.
System or Component Engine Misfire,Rough / Unstable / Erratic Idle,Lack of Power / Sluggish;DTC / Error Message;Yes - Continuously
Recommendation One at a time, disconnect both wires from each injector and insulate the terminal ends so the circuit will not short to ground on the effected bank (1-3 for P2146 or 4-6 for P2149).
Clear the codes and start the engine, check if the same code resets. If an injector is disconnected and the code does not reset, replace that injector.
