Where is Bank 2 O2 sensor for a 98 nissan frontier?

Answer 1

All v6 and v8 engines are the same. A v engine that points forward has the bank 2 o2 sensor on the passenger side exhuast pipe, before the spot where the pipes joint a single pipe. On transverse engines,(mounted sideways) bank 2 is the back exhaust manifold and pipe. Bank 2 sensor 1 is the front sensor used for fuel control.Bank 2 sensor 2 is after the catalytic convertor. If the code you have is for the bank 2 02 sensor, it does'nt always mean the sensor is at fault.

Answer 2

BANK#2 Is on the left side where #2 cyl is located. drivers side in America. Not knowing how many miles I cannot advise very well.
