On the 3.6L bank one is the passenger side. On other engines it is driver side.
That is passenger side after the catalyst.
That is the sensor in the catalytic converter.
Bank 2 - passenger side. Sensor 1 - before the catalytic converter.
it is the top sensor on the passenger side. use a box end wrench to take it out
Bank 1 refers to the side of the engine where the number 1 cylinder is located and sensor 2 is the down stream or after the catalytic converter sensor.
bank 2 is passenger side, sensor 2 is rear sensor (after catalytic converter)
Upstream, driver side.
Assuming you mean P0135, that would be O2 sensor heater circuit malfunction (bank 1 sensor 1). If the wiring to bank 1 sensor 1 is not damaged, it is probably a bad bank 1 sensor 1 O2 sensor. Replace it.
Trouble code P0042 means: HO2S Heater Control Circuit (Bank 1, Sensor 3)
I believe it is before the catallytic converter.
Bank 1 is the driver side on a Durango.Bank 1 is the driver side on a Durango.
Bank one is the driver side.
