Question about 2001 Buick Century
Light came on after oil change, car has 123,000 miles
The easiest thing to do to have that checked is go to autozone, checker or someplace like that. They test for free and can tell you what the light means. Then we can figure out what is wrong.

the service engine soon light means a fault has occurred in the engine or emission system's electronic controls, it has nothing to do with any service you did in most cases, there are over 150 problems that turn the light on, to find out what the problem may be go to any Kragen Auto or Autozone parts store and ask them to run a OBD 2 trouble code test, IT IS FREE. then post the code back here for us to look at, which is also FREE.

The error that I'm showing for error code P1133 is
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank). I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done. Hope this helps. Thanks for an honest rating and for using FixYa.

SOURCE: check engine light
This is unlikely to be related to a simple coolant flush or oil change. Obviously you should check that all your fluid levels are correct as a first step in the process. It is possible that a connection to a sensor on the engine has been disturbed during this work which can then set off the EML so check all visible electrical connections on the engine first.
If there is nothing evident from this check you need to have the car put on a scanner at a dealers to identify the trouble codes stored in the cars ECU. The stored codes will point towards a diagnoses. Often a bad sensor is the cause of a problem such as this.
Hope this helps. Please do rate this answer. Many Thanks.

Testimonial: "I am going to bring it in for a sensor check. Thank you for the great advice. "
the service engine light means that the computer has detected that there is something wrong. it doesn't mean that it is anything serious. it could be something very simple. if you want to find out what it is exactly and avoid repair shop costs, take it to auto zone or another parts store. most of them have scanners that they will hook up and tell you why the light is on without charge.
