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.

Why does my service engine soon light come on when the car is working properly but not when it doesn't?


The light is in test mode when you start, so you can check the bulb is working. The light has nothing to do with whether you stall it only estimates whether you need a service based on time, number of starts (and probably some other parameters - perhaps someone else knows what they are).

My service engine soon light just came on. I have a 2003 Buick century. What does that in tail?


Could be LOTS of things. The light can come on for a transmission issue, evap system issue... etc etc If you don't have a code reader, a local AAMCO or Pepboys should read the code and diagnose for free.

2003 Buick Century Custom and the Service Engine Soon Light


You will need to have a reputable mechanic do a diagnostic check on the car to determine the problem. This should pull up a code number in your car's computer and help point the mechanic and you in the direction of the malfunctioning part/s.

Just today, I had a diagnostic check done on mine for nearly $45.00. The mechanic was able to figure out the reason why my service engine light was staying on. I knew my car's radiator fans failed to run when car's engine was hot except when the A/C was running. I had changed out the sensors and was never able to get the light to go out or get the fans working. They were able to determine that the 25 amp fuse for the fans located under the hood was blown. After replacing it, the fans worked as they should, my car runs cooler and the engine service engine light is now out. Of course there are many possible reasons why the service engine light may come on including problems with the car's emissions. A reputable mechanic can solve your problem.
