High temps in my 240. 200

Well your symptom doesn't exactly match the one most commonly reported, but I can envision the temp comp board working for a half hour until it warmed up itself. It is located at the rear of the cluster and in a place that would collect heat from the cabin heater in season, or the sun on the dash too.

There is lots on the board about this little circuit, its failure, its loose connector, and its palliative purpose. Make a post, I guarantee you'll get lots of advice and maybe even Mr. Foster's picture.

BTW, I think there's a faq posting suggesting a re-tightening of the sender for better grounding through the threads. Sticky thermostat?
