Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
I have a mercedes vito(NNN) NNN-NNNNits in limp home mode with the fault code p2623 (fuel injectior control pressure regulator circuit/open). the fault is present and will not reset so should be easy to find so i thought! But where is the control pressure regulator i've checked both sensors on the fuel rail and they appear to be okay and not related to this fault? any help with this fault code would be much appreciated!! Thanks Jim.
close the question please.
