Are all 4 O2 sensors the same on a 03 Tiburon gt 2.7 liter?

Question

I had 4 error codes come up and it is p1167 controller adaptive test bank 2 which came up 2 times. Then p1167 controller adaptive bank 1 also came up twice. So does it mean all 4 are bad and are they all the same O2 sensors?

Answer 1

P1167 Lamba Bank control Limit Bank 2 , Sensor 1

This code is only for Bank 2, for Sensor 1, Sensor 1 is the upstream which is before the catalytic convertor. being Bank 2 this is where cylinder 2 is located.When the upstream does not work properly it affects the performance of its downstream , this is seen when the 02 sensor is not properly torque down , or wrong application, to just a worn sensor.regardless how many times it came up it just point to one sensor
