More than likely the thermostat is stuck open. You should replace the thermostat and the temp sensor. See picture below for location.

I am having problen with my 2003 GMC Envoy. The scanner show the following "code 128", what this mean.


This code indicates that the coolant has not reached operating temperature, this is usually caused by a stuck open thermostat.

Check engine light on - 2003 gmc envoy XL


That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.
