Put the key into the ignition and turn it to "Run." Don't start the engine.
Press down slowly and fully on the gas pedal, then release it. Do this three times in five seconds.
Watch for the "Service Engine Soon" light to start blinking. This indicates that the system is resetting itself. Turn the ignition to "Off" and wait one minute.
Start the Century's engine. The Service Engine Soon light will flash for a moment, then turn off. If it doesn't do this, repeat the process.
if all else fails...
Disconnect your battery for one minute and then reconnect it again that should reset it, if the problem that you have in your car is still there then that light will come on again after whille then you gona need to run diagnostics on your car to find the problem if it will not come on again then that should take care of it.
Let me tell you about my experience with my 1995 Buick Century.
When my buick sits for a while while running, the radiator fan comes on, you know?
Well, after the fan does its thing, SOMETIMES the "SERVICE ENGINE SOON" light comes on.
THEN.....when this happens again, it may take a couple times of after the fan comes on, then....the light goes off !!!
Its like it needs to go thru some sort of "CYCLE" , THEN THE LIGHT GOES OFF...
Who knows though,
you may have LEGITIMATE problems with your car.
well it needs to be serviced...soon
