SOURCE: service engine soon & brake light stays on

the service engine light is prob due to the oxygen sensor being damaged, not replace or you having the catalytic converter taken off---just messing with you. start at auto zone and have then do a free code read then go from there. you should troubleshoot the low fluid level switch for your brake fluid. unplug it and see if the light goes off and if it doesn't jump the two terminals on the harness. oh the car will have to be running. Let me know [email protected]

Disconnect the battery, wait 5 minutes, then re-connect it. If that does not work, take it to the dealer. You may not have a problem other than the computer says it is time to turn it on. You may have noticed the same problem about 50-60K miles ago.

How do you reset the service engine soon light

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.9-08-2006Let 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.good luck.

Service engine soon

Hi there:
When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.

The Four Most Common Check Engine Light Scenarios and What to Do:
* The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

* The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

The Service Engine Light means, time for an oil change and other regular maintainance items like engine air filter, check all other fluids, lube chassis, it's a reminder to take care of your car. When the maintainence is done, then you or whoever works on it resets the light, and it will come on again at the next proper interval. Every 3000 miles or 3 months whichever comes first is the standard.
Take good care of your car, it will cost you a bit, but your car will be happy and it will take good care of you. Neglect your car, it'll cost you much much more and you'll be sorry.

You need to let us know what the fault code(s) is. Did anyone ever give this information when they were working on the vehicle? There are many reasons for the check engine light to be turned on.

When I start my 2001 alero the anti-lock, traction light, service engine soon, service vehicle soon lights all stay on all the time. But my car seems to be running fine. Why is this?

the anti-lock and traction lights will come on together if there is a common problem with the two, since they are closely related. may be a wheel speed sensor or something similar. the service engine soon light indicates a problem with the engine computer, can be anything from an emission system problem or an engine performance problem. all of these lights can come on with no apparent running problems on the car. the service vehicle soon light is basically a maintenance reminder, an oil change light. take the car into a shop and have the codes read for these lights.
