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?

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!

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.

I'm having same issue with my 2016 sierra. What is the fix for this problem. Does the thermostat need to be replaced as well as the temp senor?

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

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.

      Checked the pads today and there's plenty of meat on them. If the message keeps coming up, I'll just answer YES that the pads were replaced and wait for the squeal.

      Welcome to the Forum! Always post the code definitions along with the codes. there are over 18000 possible codes, no one remembers them all and most will skip over your post rather than look them up
