Location of Downstream O2 Sensor 2001 Frontier
I am really confused about the location of my downstream 02 Sensor on my 2001 Nissan Frontier XE King Cab 2.4 l KA24DE engine. I can only find two sensors. The upstream was obvious. However I am getting mixed information on the location of the downstream sensor. The only downstream sensor I can find on my model is right BEFORE the catalytic converter. There is no sensor beyond that. Most info I am getting reports the downstream sensor after the catalytic converter and that is not the case with my situation. Any information would be appreciated.
