Added oil when low oil level light came on . Also added some coolant and windshield wiper fluid as they appeared a little low as well Next day the Service Engine Soon light (white one) came on after about 2 miles of driving.

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.

I found several shops in my area, Albany, NY that had the older code readers. It worked fine, and cost me $30.00. It showed a bad O2 sensor that I replaced myself. I suggest you go to a reliable shop. Auto Zone/Advance etc.. do not have the right code readers. Joe
