Default Coolant tempature sensor repair 02 trailblazer
My coolant tempature sensor causes the check engine light to come on. This will stay on for a while and then one day it is gone for no reason.

Trying to determine how to replace the sensor since that is the code that is generated and really cannot find anything on this
