Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. We just found out that the check engine light on our 1993 Toyota Pickup is due to a bad "knock sensor".
Low fluid levels in engine.
Problem with the emissions system.
your oxygensensor is bad ,its screwed in to your exhaust manifold, about 30.00
You add automatic transmission fluid to a 1989 V6 3.0 Toyota pickup truck through the filler tube in the engine compartment. This is also used to check the fluid level.
Check the pickup inside the distributor and see if its OK. Do you have spark at the ignition coil? Check the wires. Or the cap and rotor assy.
It could be anything, but the most common problem is the O2 sensor.

It is important to pay attention and understand why the warning lights come on. The Check Engine light will flash because there is in issue within the cars engine, the number of flashes usually indicate the code number.
Start off with 4.5 quarts. Start the engine, then turn it off. Check the dipstick about 15 seconds after turning the engine off. I'm guessing it will be about 5 quarts.

So if there is a persistant problem with the engine, the light is likely going to stay on. To turn off the check engine light on a 1999 Toyota Camry you can disconnect the battery.

Easiest way is to disconnect the negative battery cable for a couple of minutes, then reconnect. This will erase any codes stored in the computer. If everything is okay, the CHECK ENGINE light will stay off.
Check the heater core if weather not responsible.
I own a 92' Toyota pickup and i recently changed the fuel filter. It sat down between the block and the intake manifold on the back near the firewall. Check there.
