SOURCE: Oil Pressure Light Comes On after 10 min of Driving

You may not have put the right amount of oil in your car, your oil pressure sensor could be faulty, or you may have a leak.

By revving your engine, you're increasing the pressure and thus turning off the light and making the sensor think that it's at the correct pressure.

SOURCE: OIL PRESSUE LOW

At some point, your engine is registering low oil pressure and warning you the oil pressure is insufficient to lubricate the engine properly.

How does the engine know this? What causes it? Excellent questions. The engine 'knows' this because there is one or more sensors that read the oil pressure all the time. The sensors report to the computer which reports to you. They could be faulty. On the other hand, there could be times when oil pressure IS low. Your oil pump may be mal-functioning. Normally, I would expect the oil pump to either do its job properly or NOT do it properly but not act intermittently. It may warrant being checked by a professional. Another reason for this condition could be the oil itself, though you report you just had it changed. Presumably, whom ever did the change put in the proper oil grade, service and weight, recommended by GM.

Another thought, is this warning seen by you immediately after you start the car? If yes, it is normal for oil to take a second or two to build the proper pressure, particularly in cold weather. Where I am at, it is cold. Oil doesn't like to move when it is cold (like me) so it takes a bit of time to get up pressure (like me).

If this continues, you may want to have this problem looked at by a professional, as I said.

Thanks for your interest in FixYa.com

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.

Why would the oil light stay on?


That depends on the type of oil warning light being displayed. There are 2 types of warning lights

1. Low oil pressure light which all cars have
2. low oil level light which some cars have.

Low OIL PRESSURE warning means the oil pressure is below minimum and when this happens there will be insufficient lubrication of many engine parts because sufficient oil cannot get to all parts of the engine it is required to lubricate. Until the cause is identified and rectified the warning light will remain. If you run your engine with low oil pressure you will cause expensive damage to internal engine components.

Low OIL LEVEL warning means the oil in the sump has dropped to a dangerously low level (which may be due to an oil leak or abnormal oil consumption by the engine.) This warning means the oil level needs to be topped up and the warning will stay displayed until you top up the oil. Running the engine with low oil will cause expensive engine damage.
Since it is a 2 minute job, Oil levels should be checked fortnightly as a minimum, together with radiator coolant and power steering fluid levels, if you run the car most days each week as most people do.

It is possible for a warning light to remain displayed when the cause has been dealt with because there is a problem with the sender unit. However it needs to be established with alternative checks that the problem has been fixed before investigating if there is a problem with the warning light itself.

My oil light comes on after higher speeds while idling at a traffic light.


It may be your oil pressure transmitter switch at fault. There's many different oil pressure transmitter switches. Here are some generic images:
oil pressure transmitter switch Google Search
It could also be that your vehicle is due an oil/filter change.
Is your oil level ok?

It's unlikely to be your oil pump at fault.
  1. Check your oil level
  2. Is the vehicle due an oil/filter change?
The oil pressure transmitter switch simply tells the engine 'low oil pressure'. This usually happens at idling speed due to a faulty transmitter switch, low oil level or there's a need for an oil change as the old oil is no longer up to the job. Oil pressure switches are easily changed.

The important thing is that you aren't getting a warning light when driving at speed. If your oil level is okay and it isn't due an oil/filter change - it probably is the oil pressure switch at fault.

For your own peace of mind try adding an oil additive.

2007 chrysler pacifica oil light comes on and car loses power while driving


Having changed the oil sending unit it is a fair bet the oil light is operating accurately unless there is a wiring problem in addition.

Presumably you are referring to the oil pressure warning light rather than a light warning of a low oil level or high oil temperature? If you are in doubt I suggest you read your vehicle handbook.

An engine should not be operated with low oil pressure and it is risking some very expensive repairs and a lot of inconvenience if the cause is not located and rectified as soon as possible.

A common cause of low oil pressure is the engine could be dirty inside due to infrequent oil changes or poor quality oil. Another possibility is an oil pan or sump that is dented due to grounding. The suction pipe is only about a quarter-inch above the bottom of the oil pan and a relatively small dent can prevent a sufficient supply of oil reaching the oil pump.

I hope this helps.

Oil warning light flashing mean?


Normally, if you get a oil warning light signal (flashing) could be a few things related to it. Number one, you are low on oil. Check your oil level and make sure it is at full level. Number two, is possibly oil filter is dirty, ( time for service,oil change) or problem with oil pump or oil pump pressure. BUT I would first start with checking oil level and then maybe a oil change.

2007 chevy uplander ls minivan, low oil pressure warning light and bell comes on and off after 20 minutes of driving


Since you do not state whether you checked the oil and what the condition and level it was, that is important to know for advise to be given.

But unfortunantly, what you describe is some of the indications of a blown head gasket. Did you have white smoke coming out of the exhaust? Is there any indication of water on your dipstick? Is there a oily slim on the top of your antifreeze in the radiator overflow?

Where do i find the oil pressure switch on the toyota tarago is there one or to I replaced the one on the side of the motor near the starter motor but the red oil light is still coming on


First, do not keep driving if the oil warning light is on or your oil pressure gauge has dropped. Stop the engine, let it sit for a few minutes, then check the oil level.
If the dipstick shows a full oil level, then low oil obviously isn't your problem. The oil pressure may be low because of a worn or broken oil pump, a plugged oil pickup screen in the engine's crankcase, possibly a plugged oil filter or excessive bearing wear. Or, the oil pressure may be fine but the oil pressure sending unit has failed. Further diagnosis will be required to determine what's wrong.
Perform electrical tests on oil pressure switch http://www.clarks-garage.com/shop-manual/elect-19.htm
Replace pressure switch as the cheapest means of repair to see if the lights go out .
The pressure switch will be located on the engine block.

On my 93 Dodge Caravan ES 3.3L, when it comes to a stop and idles (at a light mostly) the check gauges light comes on. When the check gauges light comes on the oil gauge is at the bottom. When I tap...


Okay What it means is that the oil in your car is either low in level or the oil pressure at low revolutions is low. I highly recommend you to stop driving the car when this happen because you can internally damage the engine with a low oil or a low pressure of oil. Check the oil level first..make sure level is fine and oil looks good. Black and burned oil will give you a low oil pressure as well. If it happen that your car need a oil change. Make sure you get it done and see if the problem goes away. Very rarely oils pressure sensor goes bad but if oil is new and level is fine you can take the oil pressure sensor and connect a tester for a oil pressure. If this is not under the manufacturer specifications.. oil pump is worn out and you have to replace it for a new one.
Good luck and don't forget to rte me. Thanks

Oil light comes on when break then goes off


The oil light indicates that the engine's oil pressure has dropped below the minimum safe pressure. When the light goes out it suggests that pressure has been restored to a sufficient level for engine lubrication but this is nevertheless a bad sign.

I suspect that the oil level in the engine is too low and that the oil itself has greatly deteriorated and has not been changed for some time.

1. Check the oil level again, after the car has been standing for a few minutes, and make sure the engine oil level is at the maximum mark on the dip stick. If not then top it up.

2. Have the oil (and oil filter) changed in the car as soon as possible and ensure it is the correct spec viscosity oil for that engine .

3. Brake test the car to see if the oil light still comes on under braking.
If it recurs you need to have an oil pressure gauge hooked up to the engine (by an auto repair shop) to see what oil pressure is being achieved at various engine revs. If an independent gauge shows no problem with oil pressure then I would assume a faulty oil pressure sensor.
If the pressure gauge identifies a lower than normal oil pressure in the engine's lubrication system then the cause needs to be identified and fixed.

2004 Chev Epica - oil light comes when car comes to a stop


the oil light is coming on due to sensed low engine oil pressure, this is not a level issue unless u are about 3 quarts low, oil pressure indicators don't leave any computer codes, so who ever told u that is wrong, u need to test the oil pressure with a mechanical gage when the oil light is on, until U need to confirm that u don't have a real pressure issue here or you can burn out the engine bearings, if the pressure checks ok then rplace the oil pressure light sending unit in the engine.
