My 2006 jeep wrangler was making a noise like a belt squeeling drove about 5 miles noise stopped engine light appeared and oil pressure went to 0 (Jeep only has 38,000 miles)I imediatly turned engine off i checked oil was perfect checked water level perfect no oil under jeep really confused any suggestions

if it's not going onto the ground, and it's not being burned, check the positive crankcase ventilation and the exhaust gas recirculation valves for oil seepage...also check your air filter, if its got oil on it replace the pcv valve.

It looks like you drove your car with no oil in your engine, unfortunately you should have stopped the moment you started to hear the "rapping noise" since you could have severely damaged your engine. If the noise continues even if you have a normal oil reading you most likely would have to overhaul your engine since by driving it oil dry several parts may have resulted damaged.

Wire on oil sending unit may have fallen off or sensor itself may have gone bad. Check both. If engine has no tapping noises, likely it's not a pressure problem.

When the gauge is at 0, is there any noise from the engine (tick, knock etc?) I would have someone put a mechanical gauge on there and read true pressure.Your driving pressure seems OK but if the low number is "real" something is wrong!

The gage is working because it is coming on sometimes. The oil pressure sending unit on the engine is starting to go. I would replace the oil pressure switch on the engine first.

What Make Model and Engine. I'm sure you have tried and oil change. Try hooking up a mechanical gauge to check the pressure.

The squeeling could be from a worn belt or if oil drips on belt overnight. Replace the belt first to see if that fixes it.Good luck.

Sounds like your sending unit sensor - if it was your pump going out, your engine would be history by now. Rule of thumb, if your oil check light ever comes on, it's usually too late to remedy the problem. You have a major issue, but since you've obviousely drove it quite a bit since then and it still hasn't seized up, I'm guessing you're ok...for now. Since you took it to a shop and they said you're ok, I'm assuming they checked your level and visually checked for leaks and found nothing. Either, you've got somethijng partially blocking your pick-up tube for the pump which is in your oil pan, or a electrical issue with the sensor. I would start by having someone check the sensor out and go from there...good luck.

If there is no engine noise associated with this ow oil press reading then replace the oil pressure sending unit on the engine, it is defective, this is common on all cars.

OIL PRESSURE SENDING UNIT ON MY JEEP GRAND CHEROKEE LAREDO 1999
WHERE IS IT LOCATED AND IS THERE A DIAGRAM OR PICTURE LOCATION FOR IT

ANY SPECIAL KNOWLEDGE TO PUT IN?
