Need help finding rear o2 sensors I found 1 o2 sensor where i put in 1 simulator. It was in front of the h pipe. As for the second o2 sensor, i do not see it anywhere. My 2002 WS6 LS1 trans am does have 2 rear o2 sensors right?? I found the 2 front o2s. I need to find the other so i can put in the other simulator and so that damn SES light goes out.

First of all, my system has no cats, 3'' LT to a 3'' h pipe. I only saw 1 sensor bundle (disconnected) tucked up near the tranny, there is 1 on each side of each header, 1 more that is (hard to see) up towards the motor. 4 total. So what 2 make up the rear o2s?

From: Live Oak, FL - in the woods where the creatures lurk.
The pre cat sensor connectors are real close to the engine. There should be extensions plugged into them or else the wires extended to reach the pre-cat O2s with headers. The -original- connectors for the post cat O2s come up over the trans I believe, in any event will be the longest O2 sensor -original- wiring. Get the car up in the air and check it out, you will figure it out.
