The check engine light and abs light have been coming and turning off at the same time. the past week they have done this 5 times. they both turn on and off at the exact same time. sometimes they stay on for as little as 10 miles, sometimes 100. when they are off it might be for just a mile or two, or for a hundred plus.

my shop pulled the code on the CE light and it said it was the O2 sensor, but there was no code for the ABS light.

Anyone know what this might be and why they are connected?
