P0161 O2 Sensor
2002 C5 PCM 0161 is the O2 sensor passenger side - closest to engine Yes?
Ordering O2 sensor, wire length? Do all 4 sensors use the same amount or length of wire?
Thanks to all - Glenn in San Diego.

Is the downstream O2 sensor on passenger side and is a heater circuit trouble code…you have a 50-50 shot at it being a bad sensor or a wiring issue…and don’t buy one off Amazon or EBay because you’ll be charging it again.
