Using a six sided crow foot, remove the NOx sensor 1/1 (2) with module from the Diesel Oxidation Catalyst/Diesel Particulate Filter DOC/DPF inlet elbow (1).
If the NOx sensor fails to loosen use a torque wrench set to 160 N.m (118 ft. lbs.) and loosen the NOx sensor (1).
NOTE:
DO NOT use a torch as a heat source.
If the NOx sensor is still not loose after applying 160 N.m (118 ft. lbs.) then use a heat gun to heat the NOx sensor boss for 1 minute at 450° C (842° F).
