Hello my name is ***** ***** I can help.

When the code P0128 sets goes into a default mode.

Causing your problem.

P0128 may not turn on the engine light until it fails 3 times. But will be it history.

The most common fix is to replace the thermostat.

The thermostat is covered under the 5 year 100,000 mile warranty.

Most auto part store will check for codes for free
