A forum search reveals a trip to the parts store for a complimentary diagnostic. Return with the code and the engine gods can help. Im just a computer nerd.

I'm dealing with the same problem right now too. My VSC and CEL decided to come on and the codes thrown were: P0125 and P1135. These are apparently oxygen sensor issues and I was told that the 2 front oxygen sensors needed to be replaced. $500 price quoted for labor/parts. Now, the sensors seem to run between $80-$110 online, but the mechanic told me they are over $200 from the dealer. Seems that the air/fuel sensors are more expensive, but I dont think that is the part I need. So what do you guys make of these codes? Can I get online oxygen sensors (Denso/Bosch) that will do the job just fine?? Thanks for the help.

jason, take a look at the thread below in which we just had a recent discussion with another member who has the same O2 sensor issue:
