2015 Chevy Silverado Temperature Sensor keeps going bad


Recommended Posts

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!!

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!

like me, might be bad luck. on my 2014 i replaced the thermostat 3 times before i got one that lasted. all 3 were from gm and the last one that has continued to work was motorad

Interesting. I had the opposite experience. OEM went bad after 7 years and I replaced it with a Motorad. That failed within a couple months and I installed another GM one but went with a 194⁰ one. It has worked just fine ever since.

Most likely neither your thermostat or temp sensor are bad. Most of the time it will be battery, alternator or ecu. Try removing your negative cable for 30secs then reconnecting. Power surges can cause the ecu to become confused and lock out the temp sensor and kick one the fan to prevent the engine from overheating. Removing the neg cable allows the ecu to reset. I’m no mechanic but it has been the case with my 2014 Chevy PU. I’d say it’s time to replace battery and see if that fixes your issue

Above worked for me! Was just about to swap thr sensor when i read above and the battery reset fixed my issues. My issues were: check engine light, no AC, temp gauge all the way low on dash never going up, and the radiator fan blowing like crazy even when i shut it off. After battery reset all were immediately fixed:) 2015 silverado
