I have just found this. I have the same truck and the same problem. Bank 1 means its on the driver side and sensor 2 is the rear sensor. They come off the exaust.
Is this bank 2 sensor 1 or sensor 2?
it is the rear sensor bank 1 (the one after the converter)
It don't have a fuse for the 02 sensors.
Bank 2 is passenger side. O2 sensor 1 is threaded into the exhaust system between engine and catalytic converter.
o2 sensor Bank 2 sensor 2
bank 1 is drivers side down stream o2 / bank 2 is drivers side down stream o2
There are 4 O2 sensors in 1999 suburban.Bank 1 sensor 1, bank 1 sensor 2 on the driver side before Catalytic Convertor. Bank 2 sensor 1 on exhaust Manifold, passenger side. Bank 1 sensor 3 is after catalytic convertor.
what year is the dodge ram? 1999 dodge ram 1500 has the bank 1 o2 sensor located right after the catalytic converter
A/F Sensor for Bank 2 Sensor 1. It is the O2 sensor on the front manifold.
That is the O2 sensor in the pipe after the catalytic converter.
That should be the O2 sensor just before the catalytic converter.
your bank 2 sensor is the o2 sensor on your passenger side exhaust manifold
