First thing you need to do is put a mechanical gauge on it and read actual pressure. If OK, change the sending unit.

06 chrysler 300. When I'm at a red light, the oil check on the dash appears then a ding sound. I notice the car idles roughly amd when the light turns green and I start driving the car is fine


Ok what is wrong is your idling is to low which is controlled but a ( Throttle Position Sensor Switch) buy one of these and your problems will be gone, The ding you hear is low oil pressure warning going off once the idling goes back up the oil pressure goes back to being good.

Oil pressure on my 1996 Dodge Ram pickup is running low even though my oil level is fine


have the oil pressure checked with an independent gage as sometimes gages in the dash don`t show correct pressure. how long has it been since the oil was changed as oil when it gets dirty it thins out and can affect oil pressure. if you don`t hear any ticking with the motor running chances are the pressure is either good or just a little low. testing oil pressure with an independent gage will tell the tale.

I have 199 Plymouth voyager I don't no which fuse


The oil light is not fused by itself, the fuse that runs it runs all the lights and gauges. Let me get this straight, you are driving this with an oil pressure warning on??? Find the problem and fix it before you possibly damage the engine ands have a $3500 repair bill.

you either have a faulty oil pressure switch or you have poor oil pressure.if you find the oil pressure switch remove it and install a manuel oil pressure guage there. then you will see if it is the actual oil pressure weak or if it is the switch.

When braking the oil gauge will read at it's lowest point and a warning ding will sound but when under power and driving normal speeds it works fine.


It is normal for the oil pressure fluctuate. this is caused by the oil pump not turning as fsst and pushing less oil. When the pressure starts to dip really low it is cause by the bearing wearing out and not holding the pressure. bearings normally wear out for two reasons, one is that it really high miles on the engine, the other is running it to low no engine oil. If you don't have really high miles , then I would look at the oil sending unit first. they can get clooged up and give bad readings.

Our oil pressure light keeps coming on when the car is idleing. Every thing is fine though with the pressure, so I'm assuming the sensor is bad. is there a way to remove that sensor?? The dinging sounds...


it sounds like the oil pressure sending unit. it located a few inches from the oil filter. only takes a few minutes. the part is cheap, like 10 0r 20 dollars. maybe less.

My 96 bonneville's oil pressure drops way down when idiling,the dinging drives me crazy.it dies out ocassionally also,I changed the oil pressure switch it wasnt the problem,please help me.


Try changing to a higher viscosity oil, like a straight 40 grade.This might help for a while but it is only a temporary fix. It sounds like the main bearings or oil pump might be defective or just worn out.

1995 jetta oil light buzzer problem


You need to install an oil pressure gage. If the pressure is good then check the wiring to the sending unit. It could be a bad sending unit but don't replace it until you test the oil pressure. If you don't want to add the gage inside the car you could install it under the hood or use a manifold gage, it's mechanical so oil flows right to the gage instead of a sending unit, you don't leave it on the engine. Mechanics use them to test engines and transmissions. You can buy either at a auto parts store. If you have low oil pressure then either the pump is bad, the oil pump pick up screen is clogged, or the engine is worn out (bearings, valve guides, piston rings).

Low Oil Pressure on 1992 Chevy 1500 Pickup Truck


Hi! The problem you are outlining is very similar to the Rover V8 (Buick engine). We Brit's are used to the low oil pressure when warm. I presume a complete oil change engine flushed with new replacement filter has been carried out? Maybe a top quality synthetic oil with additive may help. You may take it a little further and replace the oil pump with an after market performance up rated one. If you really are worried about low oil pressure damage whilst in low rev's try Molybnenum Disulphide an oil additive which really reduces friction metal to metal wear particulary in the situation you are describing.
That's the best I can suggest at this moment.
Good Luck! and Happy New Year!
