Odd behaviour from my temp gauge

[jyoteen]

On Thursday, my temp gauge decided to not function temporarily. The needle was buried at '0' and the red light was flashing away accompanied by a warning on the central display. I should have snapped a picture, but oh well.

I restarted the car at the traffic light, but proceeded to have the same malfunction. This is, I guess 'lucky' since my CPO warranty runs out this week.

After some time on the return trip, the temp gauge worked fine.

Now, I wonder if the circumstances of parking on an uphill incline, at an odd angle with it also leaned to the right due to the nature of the uphill, would cause this malfunction (coolant temp sensor).

I don't have any leaks either and the coolant level is ok. I've religiously purged the coolant 3 times already (once every year and a half) at 30K mile intervals.

What could this be other than an instrument cluster failure?

Also, would a more permanent DTC be recorded in the car's computer, since the light/malfunction is no longer there?

Thanks.

More likely the temperature sender unit (on the top of the engine between the injectors on the right side).

Several folks here have changed theirs - please do a search.
