SOURCE: Low oil pressure light goes on until car warms up. Oil level is good

The oil pressure sending unit has gone bad. I sending unit is just above the oil filter and you can get to it from the top. When you face the Engine look down towards the oil filter, the oil pressure sending unit is just above that and it looks like a cylinder with two wires coming from it. If you don't see it, it's right between the exhaust manifold and oil filter.
If you go to Auto Zone or Parts Source, they'll have the oil pressure sending unit and the step by step instructions, When installing the new sensor. Do not use teflon tape or any sealant, the sensor is tapered and need's the good ground from the engine to give you right readings.
Good luck and hope this helps.

Check your oil pressure switch located next to the oil filter. Sounds like that will need to be replaced.

Check engine light is on. Engine sounds like it's knocking. And oil light is coming on. This 2008 Dodge Dakota has only 63,000 miles.


Sometimes that light means overfill oil
Sometimes after changing oil if they put too much that happens
Check the oil level on cold in level place (give it like an hour or so) for the light to reset
If after that the light still on take it to a tech.

Good luck

I have a 2002 jeep grand cherokee lerado with a 4.0 my oil pressure is normal when i drive but when i stop my pressure goes low


A low oil level will cause this. If the oil level is fine, then you need to have a mechanical gauge to verify the pressure is really low and that you don't have a bad oil pressure switch. You could try replacing the switch first if you don't want to put an oil pressure gauge in the vehicle. If the pressure is indeed low and the oil level is normal then replace the oil filter to see if that brings the pressure back up. If the pressure is still low, remove the oil pan to check the pick-up tube for debris. If it is clear of debris then you'll be needing to replace the oil pump. Another possible cause of low pressure is a damaged rod or main bearing and would require the engine to be rebuilt.

What does a low oil pressure alarm mean


It means the sensor that detects your oil pressure has seen a situation where the oil pressure is too low and engine damage will result. Could be just a bad sensor, but better have it checked with a mechanical gauge to see exactly what the pressure is.

Oil light


The oil light typically only shows a lack of oil pressure, not a low oil level. Granted, if the oil level is so low that the pump is losing the ability to pick it up, it could activate then since the low pressure situation would be caused by an extreme lack of oil. Also, when was the last time the oil was changed? A clogged oil filter or severely dirty oil could cause an oil pressure drop.

It could be an oil pump failing, or it could also be a bad sending unit (the part that sends oil pressure data to the instrument cluster). Changing a sending unit or disconnecting it and hooking a pressure gauge to the port is usually easier than pulling the oil pan to replace the pump. If it were me, I would start there and make sure it wasn't a false alarm.

Hope this helps, and good luck!

98 altima oil light on and off oil level fine car restarted and


If oil pressure is LOW this vehicle has a safety feature that will prevent vehicle from starting.(check oil level before you start) Now what I wan't you to do is to have the oil pressure switch checked or changed. This may be the reason why this vehicle is not starting or it can also be that the actual oil pressure is low. To check the oil pressure of the vehicle you will need an oil pressure guage. Remove the oil pressure switch and connect guage to oil pressure hole and check oil pressure while cranking vehicle.Some pressure testers can be connected to oil filter housing either is fine. If this vehicle has low oil pressure the reasons for that are bad oil pump, clogged oil pump pick up(from lack of oil change/poor mantainence) or bad connecting rod and main bearings but this usually have a warning from before (the engine will sound loud by knocking /clicking-tapping noise) It this was happening you may need to rebuild this engine or replace it. Good luck and Thanks for using FIX YA
