Mine are pretty accurate, and I know that the workings are simple because I know how they work. They go straight from the sender to the cluster, to a standard gauge movement. Nothing passes thru the ECM. And the senders themselves are simple, based on the charts in my service manuals.

First time I heard of this foolishness was in some Ford or Lincoln, they made the oil gauge function like an idiot light because drivers got worried when they saw the fluctuations. Maybe they should go back to putting in an optional gauge package for those who really care about what's going on in the engine and idiot lights for those who don't.
