I am replacing the coolant sensor that is located on the right side of engine. Does this one still go through the PCM and not straight to the instrument cluster? I know the one next to the thermostat housing does, hence the 5 volts there. Not like the 12 volts on the side of the head.
Shure would appreciate any help you might give here.
First step is to test dash gauge as outlined in upper post.

If it is working.
Them find another GM parts dealer and give him your vin no and tell him you want the one wire tempt sensor for the dask gauge.

Or check your local parts places for one.

Good Luck and let us know how it goes.
