Good morning, we have a Ford Mondeo in the workshop with the following problem.

When maximum power is requested, it goes into protection with the following errors

p0251 Check fuel dosage injection pump A, cam/rotor/injector - circuit malfunction

p1211 Injector control pressure - high/low pressure,

We replaced the diesel filter and checked the tank suction line OK,

Can someone give us a tip since we do not have much experience with these DELPHI COMMON RAIL systems

Thank you
