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?

If its the pump unit then it will require specialist investigation at the dealership or specialist garage
Is there a warranty still on the vehicle?

Hi,

Sadly the vehicle is not on warranty.

The engine had gotten a fully rebuild and clearly this code is from a sensor picking up trapped air in the coolant system as it was full and bleed out but after a day or 2 of driving i noticed the coolant bottle was at min and would you believe the fault code light went out..

Happy out till the next fault...😆
