ECT sensor ref. sig. voltage is 2.5 volts
I have a 95 Z28 with the 5.7L engine. The temperature gauge has been reading below 185 degrees F, which seems low to me. So in doing resistance checks, I decided to check the reference voltage that my book say's should be about 5 volts. It was only 2.49 volts. What would cause this, and how do I fix it?
