Which side O2 sensor is this: Bank 2, Sensor 1?
 

I had one replaced a few months ago and now I have this code again. I'm trying to figure out if it is the driver's side or the passenger side to know which one to replace. Anyone know which this would be?

Thx!:willy:

pass side

Thx sooooo much!!! You da man on this one.

I'm also getting a P1153 insufficient switching on my O2 sensor. Is that also the Passenger side? Thanks for info.

Steve (Connecticut) do u know which side this code correlates to (p1153)?

bank 1 = drivers side

bank 2 = pass. side

sensor 1 = before the cats

sensor 2 = after the cats

Thx Mike! Much appreciated.

P1153 = HO2S SYSTEM -TOO FEW HO2S R/L AND L/R SWITCHES (BANK 2, SENSOR 1)

The DTC determines if the HO2S sensor is functioning properly by monitoring the number of L/R and R/L switches.
