Where are the O2 sensors located on my durango 2001 5,9 rt

 

There is one behind the catalytic converter, and one right off the passenger side manifold. There may be one on the driver side manifold too

 

Ok thanks which manufakturer should you recommend

 

it depends on your emissions setup, you could have 2 or 4 sensors

if you have ca emisisons you have 2 on each side, one before and one after the pre-cat on each side before the y pipe

if you have non ca emissions you have 2 total, one before the cat and one after it.

denso or mopar brand only for these trucks or else you will have problems.

 

Thanks shrp for chiming in, but yes denso or Ngk

 

Thanks off to buy new ones.
And gaskets for cleaning TB i looked in totally black almost (probably never cleaned)
And PCV just changed.
