Hello my name is ***** ***** I can help.There maybe a pending code in the ECM.I have had thermostat codes set before causing this problem.When a temp related code sets it defaults the temp gauge to C and turns on the hold light.Most auto parts store can scan it for free.Please get back with meThank you

Thanks, ***** ***** was working this morning but then the flashing hold light came on and that's when I notice it was back to C. Car running normal switching gears fine and everything. Bringing to get checked after work. I told it could also be a bad coil pad?
Expert:  GM Bob replied 1 year ago.
If it was running rough and the engine light was flashing. Than maybe a bad coil pack.But it would not cause temp gauge to read C.
