Ok...to recap.....basically, every once in a while my temp gauge stops working (all the way to left) and my computer throws a P0115 code. Here's the thing.....I hook up my scan tool and read that the ECM is showing the correct temp but the gauge still doesn't work. As soon as I clear the fault the gauge starts working and the Engine light goes off.
Is this normal? Does a temporary fault glitch kill the output to the gauge and does it require a reset to get that temperature data flowing to the gauge again? Thanks
