Most Auto Part stores like napa or kragen will read the malfunction code for you for free. Once you get that done post the code so we can give you a better understanding on your concern. Oh if your light is flashing please don't drive it that means you are doing immediate damage.

Common problems that can cause the Check Engine light to come on: could be something like a bad oxygen sensor, faulty mass airflow sensor, failed catalytic converter, worn-out spark plugs, ignition wires, a loose gas cap or a clogged-up EGR system.

My malfunction indicator lamp is staying on and do not know what the problem is. It is a 2001 Toyota Yaris 900cc engine


It could be anything, you really need to get it to a garage and have them plug it into a computer to read the codes. Just so you know, if you fuel the car while it's running, this causes a "evap leak" code and will cause that light to go on.

Malfunction Indicator Lamp


Take your car to your local autoparts store and have them pull the codes - this is free at most stores. Post the codes when you're done. This can be caused by anything - even as simple as not tightening your gas cap (you should hear the clicks - it doesn't damage the cap).

Malfunction indication


The Malfuntion Indicator Lamp (MIL) is being lit up by the vehicle's computer to indicate there is a problem with one of the vehicle's systems.Have the vehicle scanned,write down the code number and definition,and ask whoever scans it what's involved in repairing the malfunction,and what system it is in.Or come back in here with the code number and definition,and we can help you.
