When I looked under my car, I see two post cat sensors on one exhaust one on the catalytic converter is connected to the harness but the one on the exhaust pipe is not connected. I am confused because i think it should not have a total of 6 sensors. Any diagram and advice ? Thanks
You can get guide from many sites.. i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

on my gmc i have 2 knock sensors and im not possitive if you have two or not under your intake mani but when i replaced both mine i got the same code of low input so i took the small needle out and wire brushed it clean and also traced and ran a new wire just to be safe and that solved my problem. as for bank 1,2 if it helps any my bank one is located engine side driverside and bank2 is engine side passenger side and 3 and 4 are underneath bed side. but you can see the sensors if you look real close near the headers. hope this helps

The one before the catalytic, on the side where cylinder # 1 is at. close to the exhaust mag.
SOURCE: check engine light P0031 code,
sensor one is before the converter. Sensor 2 is after the converter. :o)

Bank 2 is the bank that is farther back than the other when looking at eng from the front you will see that one cyl head is farther forward (closer to radiator than the other. this is #1 Bank) #2 is the opposite and sensor #2 is the one after the Catyliac Convertor towards the muffler. #1 sensor is between head and Cat.
