I got a new error code today PO136-- Downstream heated O2 sensor fault (Bank 1). Does this mean i will need to replace the O2 sensor? Also can anyone tell me where this is located?

Thanks,

 

I would clear the code firt and see if it comes back.

And if the code comes back, I would replace the O2 sensor with direct-fit OEM sensor (Bosch, I believe). Universal sensors seem to cause problem sometimes.

Also, on certain models (turbo), there are 2 O2 sensors and if one is gone, the other is close.
