The SES light comes on and when i scan the code I get P0157. I replace the sensor and a few weeks later BAM 157 again.. I am sure its the sensor.. I even took it to the dealer(BIG Mistake) and had the guy check it with a Tech2 and he replaced the O2 according to what the TechII told him..
No the A/f gauge is conected to the front O2 before the cat on the passengerside
