    [SOLVED] 2016 Engine Temp sensor fail (suburban 5.3)

    It’s completely random when it will cut out. I do t get any check engine lights. It will just stop reporting and then my fan kicks on high.

    [SOLVED] 2016 Engine Temp sensor fail (suburban 5.3)

    AC delco. I cant pin point the exact reason why it fails. Driving on the highway or backroads. Smooth or bumpy roads. Hot or cold outdoor temps. I just don’t know enough about the system to pinpoint a specific component or splice point.

    [SOLVED] 2016 Engine Temp sensor fail (suburban 5.3)

    So I’ve had an ongoing issue with my Engine temp sensor failing at random points. I can’t really point to a specific cause. I’ve changed the sensor twice (ac delco parts) and I’ve changed the pig tail. But still the problem exists. Could it be a thermostat issue?!? I really need help…I need to...
