Limp Mode P026654 Code won't rev above 3000rpm Sprinter 906 Poss 646.985

On my 2014 Sprinter i get a code P026654 Teach-in operating parameters for cylinder 2 has a malfunction. Calibration is missing. Then when it Warmed up i would get a code P215011 Power supply group B short, and then when this appeared No2 injector stopped working all resistances checked out. I swapped injectors with No3 and changed Wire to all 4 injectors but fault still showing P026654 on No2 injector and no communication to Re code them (iCarsoft CRPro+). I'm wondering if Ecu faulty? as running out of ideas. Thx

Please explian what you changed.

Thx for reply. I swapped No2 and No3 Injectors over to try and eliminate whether injector at fault and also the wiring renewed to all 4 injectors to try to eliminate hopefully any wiring fault.

Sounds like the ECU has lost the calibration for the injector. I'd guess a session on Star is needed.

Thanks for reply, I tried to put the code in but keeps coming up with communication error and won't let me clear this fault. This is the reason i hate Delphi injectors. I remember having problems with them on Mk6 Tdci Transits.
