Oxygen sensor bank 1 or 2 location on gmc canyon?

Answer 1

the GMC canyon doesn't have bank one or 2 it is an inline engine, there are two oxygen sensor however, position one and two, one is the sensor before the catalytic converter usually closer to the head, the second one is after the cat pos 2. if number 2 sets a code it usually means u have a bad cat, people try throwing sensors in but 10/10 doesn't fix it, the sensor monitors the gas coming out of the cat and usually doesn't vary. if position one is bad it will set a code as well, some of these codes set have an updated calibration for the computer that you would have to have programmed at a dealer. pos one is easy to change as you open the hood and on the passenger side of the truck on the exhaust manifold it is right there, very easy.
