Hey guys, my service engine light came on on my 2011 max, so I hooked up the scanner to the obd2 and it said o2 sensor circuit bank 1, sensor 1 (code p2a00). Would anyone know where that particular sensor is located? I wanted to pull it out and clean/replace it.Some have told me it’s near the firewall, but then I found a couple diagrams saying it’s near the radiator. Thanks again guys.

 

You could try looking in the FSM.

It only says what type of lube to put on the threads when reinstalling them

 

It took me less than 3 minutes to find page EM-30.
