P0128 Fault code - chris_yorks - 10:th-Jul-2017
Hello all and thanks for reading this.
Daughters GTC has P0128 fault code and A/C off due to high temp with fan running on full speed & temp gauge on dash not moving above 50 degrees.
New thermostat fitted - (old one was passing a little when cold)
Symptoms the same.
Looked at the service manual pages - should I now be looking at replacing another sensor in the radiator?
Many thanks.

Thanks for all help.
After a couple of journeys with a new thermostat, the fault cleared. I did read somewhere that this my take a few drive cycles to resolve.

Yes it can take up-to 50 cycles without the fault being present before it deletes it from the system.
