2015 Chevy Silverado Temperature Sensor keeps going bad

[Ronnioe Walls]

I have a 2015 chevy silverado and the temperature sensor keeps going bad. I have replaced it 5 times in the last year and a half. This doesn't seem normal. Any ideas what may be causing it? I have replaced it with several different manufacturers and some times they last longer than others. Please help!!

I'm curious...have you replaced with a GM/AC Delco part?

Ever replaced the thermostat?

The symptoms of a bad thermostat in these trucks - with the gauge pegging at the bottom - almost mirrors that of a faulty temperature sensor. I replaced the sensor first only to find that, while it did make the problem go away for a short time, it never really did fix the source and eventually it came back.

 

Have you only been replacing the sensor and not the thermostat? If so, I would bet money the thermostat is the root cause of your troubles. Please keep us posted!
