Question about Buick Cars & Trucks
3.8 ltr V6 LeSabre
The check engine light covers about 60 different sensors. It could be anything from a loose gas cap to a head gasket. The best way is to have the scan done. Some shops do this free, some charge an hours labor. Personally, I'd go to WalMart and buy one to have. $99. This will tell you everything you need to know. Good luck

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.

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.

you could go to an auto parts store and they can reset it for you, or you could pull your battery cables off the battery and hold them together for about 10 sec. that will clear any codes.
