could low brakes make the engine light come on?

I just did all four of mine. I got Walkers from oxygensensors.com for $113.00 each and free shipping. I wanted to take pictures of the process, but I had another car on the lift, so I did it with a floor jack and stands. That made picture taking more difficult. The job took about 30 minutes. The hardest part was stopping the bleeding. There's lots of sharp stuff between your wrist and the plugs for the sensors.
