Don't panic - went through this last week. Replaced sensor & still not right.
Turned out to be combo - bad sensor & faulty lead connector to sensor. Replaced
both & everything is fine.Sure had some anxious moments. When oil level was OK,
no lifter noise & no temp change, I had a pretty good hunch.Analog guages are on
the top of my list - tired of lights & buzzers! Good Luck - MAX
