As far as I know, the oil pump and the brake system have nothing to do with each other. However, the brake system uses enging vacumn to assist braking. When you push down hard on the brake pedal, it causes the engine vacumn to diminish. This may result in the engine not getting enought fuel, because vacumn is involved in determining fuel mixture. If the oil light goes out within a second or two of releasing the brakes, I wouldn't worry about it. If it stays on for longer than that, it could mean that the engine needs to be serviced. If you have not had the spark plugs changed since the car was new, it is time to change them. Also, the air cleaner element probably needs to be changed.

ABS = Anti-Lock Brake SystemIf you have this light come on while not braking, it most likely means there is a problem with the electronic controls in your brakes. If it comes on while you are braking, it means the Anti-Lock has kicked in. It should only do that however, if you are braking really hard.

Mechanic comes from the greek word for "an engineer"

Braking in a moving vehicle is applying the brakes to slow or halt movement, usually by depressing a pedal. The braking distance is the distance between the time the brakes are applied and the time the vehicle comes to a complete stop.

Either the master cylinder is low of brake fluid, the sensor is defective, or you have another problem. Check the fluid level and add if necessary. If it is not low time to seek professional help.

You should be able to go for about 30 more miles of driving. You should not go too far and should stop to get gas soon.

You should bring it in for service to a trained mechanic. The airbag light comes on when the computer has detected a malfunction.

Lucky for you, the 2001 Toyota Corolla comes with a timing chain and is good for the life of the engine. No need to change it.

The braking time is 2 - 1.5s = 0.5s. The final velocity, if the object comes to a stop, is 0m/s.

It means there is a problem with your braking system and should be serviced as soon as possible. Your brakes could fail at any time.

It's the antilock braking system. The light will turn on momentarily when you are starting the vehicle to show that the system is functioning properly. However, if the light stays on for more than a few seconds after starting the engine, or comes on as you are driving, then the diagnostic unit has registered a fault somewhere in the braking system which needs to be checked out as soon as possible by a qualified mechanic.

Squeeze and pull till it comes off :)

Replace the tranny fluid, if check engine light comes back on, replace shift solenoid.

I do believe the gas tank size on a 2001 Corolla is 13.2 gallons. the gas light usually comes on around 10.5 gallons

Indicates a braking system malfunction! Problem with the master cylinder - or - the ABS pump is not operating. Have it checked out right away.

There is no real advantage when it comes to where the used car was located when it comes to buying a used car. You should always buy a used car from a reptitable dealer and always have the car check out with your local mechanic.

Mechanic is a greek word and it comes from the word "μηχανή", which has many meanings. One of them, the most common in modern greek, is "engine".

Yes A 2002 Toyota corolla has a low fuel light that does come on. It should be located in the lower right hand corner of your instrument cluster. It comes on when the fuel gage is almost on E. When I say almost on E i mean almost on E. You will probably have about 1 1/2 to 2 gallons of fuel left in the tank. Jason Night_train06@hotmail.com

It uses voltage from the alternator which in-turns comes from the battery.......

when gearbox fault light comes on, it means there is a problem with the gearbox. you need to take vehicle to a mechanic
