It sounds like the computer. Check with your local Auto Zone store. They may offer free a diagnostic. The Auto Zone here will run a free computer diagnostic. It lets us know what codes the computer is throwing. When you find that out, you can then consult the repair manual for those particular codes. Good luck. Emerald
A problem has been detected with the EMISSION CONTROL SYSTEM if the symbol of an engine lights up solid in your gauge cluster when the engine is running . If the engine symbol is flashing , an engine misfire has been detected
The check engine light is flashing due to a problem with the emission system. I flashing check engine light usually indicates a random engine misfire.
If the check engine line is flashing then that means there is a real problem and you should have it looked at, But if the light is on and NOT flashing the it is most likely a problem with the emmisions system and most likely an oxygen sensor.
The electrical system is 12 volt negative ground. Really about 13.6 volts while the engine is running, though.
Flashing traffic lights are used when the control system is not functioning properly, or when there is very low level traffic (to the point that lights become unnecessary).
Alternator is not charging the battery. When you turn on the lights the system doesn't have enough power to keep the engine running.
lights flashing on an a/c control head usually indicate a pressure problem in the .c system. possibly low on freon
Start the engine, turn fan to high, full cold, air to panel. Press and hold top and bottom buttons on the left side until all lights flash. System will run a self diagnostic, if at the end only one light is flashing you are done. If two or four are flashing you will need to take it for service.
Red always mean stop. There are many warning lights next to the speedometer. Check engine will look like an engine and a flashing check engine light means you have an engine cylinder miss and should stop driving the car until you can have this fixed. You will ruin the catalytic converter and O2 sensors if not. There is also the oil pressure and charging system lights which mean stop and have this repaired. All these are on the left side. On the right side is the brake light which means there is a problem with the brake system.
electronic short in computer system or a short in a current of the main circuit
By "OFF," I have to assume that your question means that the ignition switch is "ON", but the engine is not running. IF that is what your question means, then the reason the engine warning lights turning on is that the manufacturer designed the system that way to show you that those warning circuits and lights are working, and ready to warn you after you start the engine, should there be a failure in one of the systems they represent.
If your check engine light stays on with your engine running , that indicates a malfunction with your emission control system has been detected . If your check engine light is flashing on and off with your engine running that indicates a spark plug ( or spark plugs ) are misfiring . Have your vehicle scanned for any trouble codes in order to diagnose and repair the malfunction
