Question about 1992 Toyota Corolla
Has been leaking oil but checked and is full, however oil warning light comes on and off mostly when putting on the brake then upon acceleration goes out again....
Not saying that this is your problem but it might be your oil pump is getting weak or your oil pickup is dirty. I would start by changing the oil and filter.

The brake fluid level sensor in the master cylinder is stuck in the lower position which completes the circuit to illuminate the light.. Try tapping lightly on the side of the reservoir to loosen it. If that does not help, you will need to replace the level sensor.
Thanks for choosing FixYa for assistance.

You have one of two problems.
The most common issue it low brake fluid in the master cylinder. As the brakes wear down, the brake fluid level drops proportionally. On the side of the master cylinder is a sensor, that measures the fluid level. Open the hood and check the level. If is is anywhere close to the "MIN" line, you may have some brakes that need replaced.
The second issue, and it is more rare, is the park brake cable rusting, and hanging up.
Easy way to check either: When the light comes on, open the hood and unplug the wire going to the sensor on the side of the master cylinder. If the light goes out, your fluid level is the issue.
Thnaks for choosing FIxYa for advice!

most likely your master cylinder is acting up try to press hard on your break for a period of time and see if the pedal will sink/replace master

If the float is blocked in the brake fluid reservoir, then it will indicate that there is low brake fluid.Actually its full, but still it will indicate, that its low fluid, due to stuck-up reservoir float.Many a times there is air bubbles got created in the fluid reservoir and this cause the problem. Just get the fluid drained and refill the fluid to its required level, then check.Also get the filter checked.If its blocked or clogged.It has to be replaced.The clogged filter does not allow the float to properly float up to the connection point and causes the brake light to go on.------------ if all checked ok, then another possibility is the parking brake engagement sensor, a mechanical switch that is engaged when the parking brake lever is activated. It may have gotten stuck in the on position and need to be cleaned or replaced.------------- This should help.Thanks.Helpmech.

Yes, the oil is the life line to the engine, without proper pressure or circulation the engine will die, no different than us humans. The reason why the light goes off is that the engine is running at higher RPM pushing more pressure to the sensor therefore it turn off the light. When the engine running at low RPM the oil pressure is low therefore it not enough pressure to turn off the switch. 1st. it cheap, replace the oil pressure switch and make sure the oil dip stick at proper level. If replacing oil pressure switch does not rectified the issue, the oil pump might be going bad and not pumping proper pressure. Replacing oil pump is a major job. remember, on any vehicle, if it run proper there should be no lights on and that is the reason why they put the lights there for a reason. Check and see you have a small oil leaks.
