Question about 2000 Ford Expedition
Hi Temp Low Oil light comes on periodically at idle when very hot out and Oil Pressure Gauge instantly drops to zero when this happens. There are no noises coming from engine
this problem sounds like a bad ground to your gauges first check your fuses with a test light take the end of light ground on battery with a long wire with alligator clip on end so you can reach around to test second thing take probe tip touch pos of battery to make sure tester lights then test all fuses first both sides most fuses have two little holes one on each side on top to put probe on fuses should light up on both sides some fuses wont light on both unless the ignition is turned to acce or for instant a headlight switch has to be on to test fuse if fuses check out okay you will have to get into the gauge instrument cluster possible if these gauges are pushed into a pin type or flat circuit board its possible loose scews and a good bump would make a bad contact in the cluster

This has an electric pressure gauge with a sending unit. Try this: When at idle, SLOWLY increase the engine speed. If the needle on the pressure gauge all of a sudden leaps to a pressure (like 'real quick') and acts normally with even faster engine speeds, the sending unit is bad. (It is just not reading the lower pressures.) Zero engine pressure will manifest itself in a bunch of knocky sounds and lifters that aren't pumping up and therefore "ticking" loudly. You probably don't have that since you didn't mention these problems.
Replace the sending unit after the above test and you should be fine.
