In the dashboard of your 1990 Dodge Caravan, the oil pressure
gauge has a 'H' and 'L' reading which means that when the oil
pressure is high, the indicator points to 'H' and vice versa for
low oil pressure.
Ideally, the indicator should point at the centre of 'H' and 'L'
which is normal oil pressure.

You have been heavily low on oil if that easy got here on. a million/4 to a million/3 up the dipstick continues to be too low to run the engine. bypass get an oil substitute, they are in a position to tell you if there's a leak for loose. 4600 miles could be ok for an oil substitute era yet that doesn't recommend you could overlook approximately checking the oil point with another replenish. ideal oil rigidity, sparkling oil and a sparkling clear out is the main inexpensive and easiest thank you to maintain your motor vehicle on the line. overlook approximately it and that's the #a million reason automobiles die too quickly.

H or high pressure could be a dirty or clogged oil filter restricting flow, or if the oil is the wrong viscosity (thickness) or is way too dirty.
L or low pressure could be a lower than normal oil viscosity or not enough oil in the pan for the oil pump to flow.

I hope the others are right, because I get the impression these gauges don't work very well or don't last long. Years ago, cars had non-digital clocks and few worked for very long.

It will be either one or the other. If L, it means the pressure is too low, and if H, it means it is too high. It should be in the middle once the engine has warmed up.

you could have a bad wire connection on your gauge or sender or there might be corrosion on wires /maybe in your connectors

if its close to the high, then your pressure might be a bit to high, and visa versa
