Does anyone have a 100% definitive fix for this issue yet. I recently have replaced my third sensor (yes AC Delco), and also replaced my battery within a week ago. I still have the dead needle and all the other associated failures. I did the battery reset trick and my sensor worked for about 5 miles down the road, and then back to failure mode. That alone tells me it's gotta be electrical or ECU issue. No way a thermostat will cause this. Mine sensor will randomly decide to work and not work when it wants to. Love my truck, but it might be time for trade-in. 2015 Silverado Z71
