Question about 2002 Chevrolet TrailBlazer
Sounds like the thermostat may be stuck open or
has anyone put a colder thermostat in the car,because once it starts to
get cold it will throw a SES with a colder then stock thermostat.
Code PO128; coolant temp below thermostat regulating temp. Replace the thermostat and that should address your issue.
Thank you for using fixya and good uck
