Question about 2003 Buick Century
I have a buick century 2003. When it came time for my oil change 3 months ago my service engine soon light came on. When the car was serviced the light went off. When I had my oil changed this time my light stayed on. Buick man told me they did not reset the service engine light, Dealer wants to charge me $85.00 to diagnose the problem. Where is the reset button located.
My service engine light was caused by a cloged passage from my EGR valve. Mine is a 3.1 with fuel injection 2003. All I needed to do was pull the two bolts over the intake plenum and remove the vacuum connection to the PCV valve. Then clean out the EGR port just below the vacuum connection in the throttle port. I would remove the rubber intake to vacuum it out. The carbon was like rock in there. Service engine light cleared on its own.

The service engine soon ligth is not the same as the change oil light. The change oil soon light you only need to turn the key to the on position and pump the gas to the floor 3 times with in 5 seconf\ds and wait. You will see the change oil light blink 3-4 times and then it is reset. The sevice engine sooncan be anything from a loose gas cap to a bad sensor such as a MAF. I just had to change that as the car was not getting poower on accerleration on my own car. The best thing to do is get someone witha scan tool and read the error code for the light and take it from there. You can buy code scanners that are OBDII compliant for arounf $50.00 and they are simple to use. If you can not do that then get a gargae to read the code for you and if you tip the mechanic a bit he will do it for free, if you know what I mean. to read the code takes less then 5 minutes.

Engine soon got nothing to do with oil change engine soon is on because you have a bad sensor to reset the light you disconnect the battery for 1 minute if it not a hard problem the check engine soon will be off but it wont fix it good luck pierre
