Check gages light
My check gages light comes on and off on
my Jeep Grand Cherokee laredo, and has
started rattling when I drive. What could be
the cause of that.
The "Check Gauges" light means just that. Look at all the gauges while engine is running and see which one is not in it's normal range. Gas gauge doesn't matter. Temperature gauge should be about 195 degrees, voltage should be about 14 volts, and oil pressure at idle is about 40 psi. If any of them are not where they should be, take a closer look at that function. I suspect it is the oil pressure gauge is trying to tell you something, especially if you say there is a rattle when you drive (engine clatter).
