Where is cylinder #1 on a 5.7L Hemi??
I need to replace an O2 sensor. OBD reader says Sensor 2 bank 2. I know which sensor is sensor 2, but I'm not sure which cylinder is cylinder 1 so I can't figure out which side to change.
Sorry for the noob post, but I didn't have any luck searching and I really need to get this thing swapped in the next few hours.
Thanks so much for your help.

O2 sensors are in your exhaust not the actual engine and nowhere near your cylinders. The oxygen sensor you need to replace should be the passenger side sensor behind your cat toward the rear of the truck.

yeah I know where they are. I think I just didn't type my question clearly. I was just trying to figure out which side of the motor was "bank 1" and which was "bank 2"
But you did answer my question..... thanks so much
