I experienced twice an orange engine oil pressure warning light and after the car wont move. I switched off the car and after ten minutes it moved. what is the problem


While an electrical fault or a faulty switch could put the light on, it is such an important light it should never be ignored and the reason for it established immediately. As far as the owner is concerned that means lifting the bonnet and checking the oil level and adding more if the level is low. If it isn't low the car should be recovered to a repair shop. Driving further could be very expensive and very inconvenient...

If the oil pressure light has switched on because the oil pressure is low then continuing to drive will soon wreck the crankshaft bearings or cause crankshaft or camshaft seizure. Damage happens so quickly if the oil pressure is lost at motorway speeds the engine is likely to be severely damaged by the time the car is stopped.

I strongly suggest you have the reason for the light switching on established and repaired.

When stopped oil gauge reads 0 what could this be and is it expensive to repair a shop?


Year/make/model?? Possible defective oil pressure sending unit causing a low reading or the vehicle may in fact have low oil pressure at idle. If this is the case, it could be caused by a weak oil pump/restricted oil galleries or main bearings getting worn. With that being said, it very well could get expensive to repair. My advice would be to have the oil pressure checked manually with a gauge to see if there is actually a pressure problem and if so , discuss your options with your repair facility

Dodge Neon low oil pressure


Hi John, Im AL the owner of Big As Auto Repair.

John, Low oil pressure can be many things. BUT, first you need to hook up an oil pressure gauge just to make sure its not the oil pressure sensor. If you have already put a new sensor on and it still has low oil pressure then you still need to check pressure with a gauge to make sure its not in the wiring or connector. If you find good oil pressure with the gauge then it need to be check to see why the pressure is low. It could be oil pump OR bearing issue. Hope this helps and please visit my auto-repair-website here: http://www.bigasautorepair.com/

Oil light for low oil pressure on


The lite is there to warn you that there is something wrong, could be low oil level, check the oil level, could be that the sender unit is defective, get the oil pressure checked with a mechanical gage to verify oil pressure. If the mechanical gage shows low oil pressure with the proper oil level then you need to have your unit repaired

How can I fix my car with the oil light coming on. The engine does intermittent jerking during driving


Oil light usually indicates LOW oil pressure.. Which will kill your engi ne and cause very expense repairs. FIRST Check oil level, If the level is good. You need to find out if the engine really has low oil pressure. A new oil pressure switch is about $8.00 you might start there. If the light still comes on its a good posibilty your car has bad oil pres.. To find out for sure you will need to install a Pressure guage and check the actual pressure.. If the Oil Level is good and you still have low oil pressure The engine has internal wear or damage.. You should not drive it till you fix the low pressure problem. rebuild or replace engine. The intermittant "jerking" can be unrelated to the oil pres problem or you engine is going away because of the pressure problem.

Low oil pressure on 2006 chevy monte carlo.


Hi,
you do not state the figures for the low oil pressure. There are various reasons for low oil pressure in an engine.
One fact is correct, if you continue to use the vehicle with low oil pressure being developed, you will be looking at an engine replacement or full repair in the very near future.

Good luck.

Low oil pressure, is it the oil pump?


Attach a pressure gauge to the oil pressure gauge after removing the oil pressure gauge, to see if the pressure is within specifications. If it is low, then the oil pump is worn out.

Good luck on this repair.

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.

Low oil pressure


If low oil pressure is verifiable the only repair is replacement of the oil pump assembly.

Start by verifying oil pressure with a mechanical oil pressure gauge. If oil pressure is low then replace oil pump.

Oil Pressure Light


Chances are you do have low oil pressure, you should have a pressure check run with a mechanical test guage to verify the low oil pressure, for now assume the oil press is low, I wouldn't drive the car, you run the risk of damage to the engine bearings, a very very expensive thing to repair.
