O2 Sensor Questions
Now I know that my many of you ignore the down stream O2S12 sensor. That said, 1 I want the dumb SE light to go away and 2, trying to get my skill and knowledge up again.
On my recently purchased 2001 Trans Am WS6, I am constantly popping the P0137 O2 Sensor Circuit Low Voltage Bank 1 Sensor 2
I believe that Bank 1 Sensor 2, is the After Cat Driver Side. I have replaced this Sensor.
I ran some live data stream test and a few various days on my Actron CP9680, here are the results
Bank 1 Sensor 1 - Frequently drops below .100, and generally stays low.
Bank 1 Sensor 2 - dang near always sits at .030
Bank 2 Sensor 1 - Frequently drops below .100, but does bounce up to .700-.900
Bank 2 Sensor 2 - generally lives around .725
From what I have read, the .030 is not where it should be. Could I have a bad ground or wire? Am I missing something else. Personally, I question, all the stupid sensor readings.
I have only had the car for 6 weeks now, so I am still learning what she has had changed. I know the car has an After Market Muffler, and unsure yet if any other exhaust work has been done.
Thanks all, for any help....
