check engine light came on. went to autozone and pulled the code. told me i had a bad O2 sensor on "bank 2, sensor 2". i figured that sensor 2 is the one after the cat but i dont know which side is bank 2. i called the crappy azz stealership and they told me that which ever side of the motor is sitting further back is side 2!!! wtf?!?! any of you dodge gurus have a clue?! and i got to get it inspected today so i can renew my tags! one of my buddies pulled me over last night to tell me that my tags are dead and i have an inspection violation!!!!!

 

Bank 2 is passenger side.

 

thats what i was thinkin but i wanted to make sure and none of the d-bags around here that i called acted like they had a freakin clue!!! thanks bro!!

 

No problem. I have to replace the drivers side rear on mine today.

 

Sensor 1 is always upstream or before the cat, Sensor 2 is always downstream or after the cat, but Banks can be confusing since they are dictated by the location of Cylinder #1.

In the case of our Rams, cylinder 1 is on the drivers side so that would be the side of bank 1.
On other vehicles, it will not always be this way. A Furd Taurus comes to mind where Bank 1 is on the passenger side.

 

Good info,,,, learning all the time.

 

sweet thanks hammer! turns out i wound up not needing it. i got to the house and noticed that the light was out so i went and had it inspected and it passed. so im good to go for another year!! only cost me 213 bucks!!! lol

 

Good deal man, glad to hear you got by without having to change the sensor.
