Review: 2003 Jeep Liberty - Fixed P0161 Error Code - Had a Bank 2 Sensor 2 Downstream code P0161 code on my 2003 Jeep Liberty. The part came in earlier than expected from seller. I've driven the car a little over 100 miles since replacement and No Codes thus far... The night before replacing the sensor I drove home from work then got under the car in my driveway and sprayed the old sensor down with PB Blaster while exhaust was still hot and let it sit overnight. Next day I used the special 7/8th inch O2 sensor wrench with an 18 inch breaker bar and the old sensor broke free very easily. I spun the old sensor in and out slowly so as to not mar the threads. I then cleaned the area and threads. Put the new sensor in using a little more Anti-Sieze on the threads than what was supplied on the sensor (very little supplied on it). Torqued it down till the crush washer seated... Time will tell how long it lasts but Allll good so far...
