Nv300 fault code P1028

[Elmo_C]

Hi all,

Looking for help on a fault code that i have on my 2021 2.0 120 nv300.

It has the stop sign and service light on and the traction control light is on also.

The van drives perfectly fine 99% of time but gives a bit of hesitation the odd time.

Diagnostic is showing fauly code p1028-38 Electronic pump unit.

I cant seem to find anything relating to where i should look for the problem.

Anyone be able to shed light on the issue? Thanks
