Had a motor swapped into my 2014 Chevy Equinox (2011). The coolant temperature sensor keeps failing. What am I doing wrong.

 

keeps failing means what? If you mean a dtc keeps setting; post the code. a fault in ect system can only be in the sensor, wiring or computer.

your first post; so in the future post questions in the equinox section not the welcome area.

Code P0128. Coolant Temp Sensor has been replaced-Codes reset then Temp gauge works for awhile as well as A/C then it fails.

 

Welcome to the forum. Moving to the Equinox section.

 

[QUOTE=KingOfHarts76;488018]p0128 is a thermostat rationality code...when it sets the pcm detects the engine isn't coming up to temp in a set run time. If this is the only dtc and you have zero coolant temp sensor codes; replace the thermostat...its stuck open.
