Check Engine Light - P0153... any takers?

[Riles]

Hey guys, my check engine light came on today, and it gave P0153 - CKT Slow Response (Bank 2 Sensor 1).

I'm assuming that this is an O2 sensor, but I'm not sure which one it is. The engine is running great, so I'm also assuming it is just a faulty sensor.

Can somebody shed some light on this for me? Thanks a bunch!

it actually means - "HO2S Slow Response Bank 2 Sensor 1"


heated O2 sensor....

I believe it is pre-cat passenger side.

LOL!! I was going to suggest it was the driver's side! It's definitely the pre-cat O2 sensor though. Since cylinder #1 is on the right side, I assumed that was Bank 1. I could be nuts though.....
