Oil pressure light comes on while on stop light, goes away when speeding, heats up in few minutes if standing with break pedal pressed

If this light comes on you need to check oil levels and top up if necessary. If the light still does not go out, chances are you need to replace the oil level sensor.

Keep driving & you won't have to worry
about the motor anymore

With the oil light coming on and the brake pedal being hard to press I would say that the engine stopped hence no vacuum -no power assist from the booster.- hard brake pedal. The lock uo feeling may come from the engine seizing up while you were still in gear

Verify that the engine has the proper amount of oil. The inertia from accelerating may be moving the oil in the oil pan away from the sensor and causing it to send a signal, then when you slow the oil levels out and the sensor go's off. I've had this happen alot with a taurus that I owned. The simple solution was to top off the oil to the correct level and the sensor did not come on again (until it ran low again, had a leaky oil plug on oil pan).

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

The oil lights come on because there isn't enough oil pressure in the engine... When you come to a red light, the engine is at idle in a lower rpm and there isn't enought oil in your engine to cycle, thus creating low pressure, and the indicator comes on, however when you rev your engine or press the gas pedal, the remaining oil that you have in your engine is being cylce because of higher rpm, thus bypassing the oil sensor. Solution to this, is you need to add oil to the apropriate oil level AS SOON AS POSSIBLE or get a oil change before driving this car any longer as major mechanical issue may occur if you do not get this taken care of. You can buy a quart of oil at walmart or your local gas station and add it and get you by until you get it to the gas station. You may want to constantly keep a eye on the oil level as maybe your engine is burning oil, in order to avoid engine break down.

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.

this is an oil pressure light, most likely the sending unit for the gauge is defective,but I do recommened a shop hook up a oil press test gauge and verify u do't really have low oil pressure, then if that tests ok replace the sending unit on the engine.

when you press the brake pedal the brake master cylinder vacuum booster takes vacuum away from the engine and that slows the idle speed just enough to trigger the low pressure oil light. Pull the oil pressure sending unit out and hook up an oil pressure test gage, if the pressure is above 15 PSI hot engine idle in drive replace the oil pressure sending unit.

I had the same problem with my 2003 Lancer OZ. The oil level and pressure were ok. Car was fine with no light when starting. After 10 to 15 mins of driving it would come on when I was stopped. It would go away when I pressed accelerator. Try replacing the Oil Sending Unit. It's about $10 and easy to swap. That was my problem.
