replace the thermostat

I have a 2004 Gmc Envoy putting out a code of 0128 what does this mean?


It means the car has not reached operating temp. The computer wants the engine a certain temp so it can go into "closed loop" where it fine tunes the fuel mix for optimum economy and emissions. If it cannot reach that temp it sets that code. You either have a low coolant level or a stuck open/missing thermostat.
