P0140 P0138 Code Chevy Truck, If you have a P0140 or a P0138 code in your chevy truck this video is for you. I will be showing you a few things you should check before replacing the oxygen sensor in your Chevy truck. Both these codes p0138 and p0140 are both for the bank 1 sensor 2 O2 sensor.
If you having trouble locating the right oxygen sensor I also have a video on that here: https://www.youtube.com/watch?v=tYUkcz64VU4
