Ford transit: error codes p1554 p1664 are they related to pump

This answer was rated:

error codes p1554 p1664 are they related to pump or ecu problems???????????????

Hi there hope i can be of assistance,

Ok the p1554 is an injector fault code, cylinder 4

The P1664 fault code is for the injection pump.

If this is a common rail, have the number 4 injector removed and tested.

If this is not common rail, then have the timing chain checked> if this is ok, then its likely to be the injection pump which has failed.

Thanks Bob
