    Code 31 can be anything from loss of power, it could also be a map sensor you will first want to clear you ECU and there are videos on YouTube to show you how to do that. If this doesn't help then we need more information on what the car is doing/problem. Good luck

Brake pedal goes straight 2 th floor!

You are definitely getting air into the system from somewhere. Look for wetness at all 4 wheels, around brake pipes and hoses and at the back of the master cylinder where it is bolted to the brake booster. You find where the fluid is getting out you find where the air is getting in.

Where is the anit-knock sensor on a 1996 4 cyl toyota camry

Should be on the side of the block facing the firewall. It may or may not be contacting coolant so you may have to drain the radiator.
Keep in mind knock sensors almost never fail. You may have an engine component making a noise or vibration the sensor is picking up.
The sensor is supposed to sense spark knock and tell the computer to adjust the spark timing down.

My 1996 toyota corolla as an error code 12 what does this mean

This is about your camshaft sensor diagnosing a problem.. The Code is saying the timing is over ******** on bank 1. You could have a bad cam sensor or if there is a knock sensor on both banks, the engine is trying to adjust to eliminate a knock on bank 1. Sometimes if there is an air leak in the intake manifold it also can allow extra air into the cylinders on bank 1. The extra air will register as a lean mix and the engine will try to compensate by retarding the spark to enrichen the fuel mix.

You can have the engine running and use a spray bottle of water and lightly mist the seams of the intake manifold. A change in RPM will prove there is a bad gasket or loose bolt on the intake manifold. Should you find this problem, work to repair this problem first.

Engin light stays on in my toyota corolla

the car has been back to the dealer 4 times for the same problem. First time they claimed that they replaced malfunction tank by-pass vsv and codes mentioned are P0440, P0441 and P0446 that were malfunction. the second time they connected the car to their computer and re-scan the vehicle and told us that everything is working fine and the engine light is off, but after one day the light came back and the car went back to the dealer for the third time and now they claim that the problem is from charcoal canister and has to be changed. also after the second visit as soon as i got in my car i could small gas and it hasn't gone away and the dealer says they did nothing wrong and all the problem is from the canister. we really don't know if we can trust what they say.
