RE: help me please!!
From your post sounded like you had a fuel pressure guage.You can clear the codes if you have a code scanner or a programmer that clears codes. Since your losing power there is something wrong. If you have a tuner installed. Check the harness for the connections.
Heres what the codes mean.
P2121 Pedal Position Sensor 1 Performance / Rationality
P2122 Pedal Position Sensor 1 Low
P2149 Fuel Injector Group 2 Supply Voltage Circuit
P2146 Fuel Injector Group 1 Supply Voltage Circuit

Codes 2121, 2122 can be traced back to the fue l(gas) pedal. There is a cable that runs from the pedal into the engine compartment. Check the cable.
The other two codes might be a bad ECM or check the injector harness and wiring. This may be required to take to the dealer or a good diesel mechanic to verify.
