The dealership should replace it free of charge. repair rhe code you need: Check and fix any exhaust leaks Check for wiring problems (shorted, frayed wires) Check the frequency and amplitude of the oxygen sensor (advanced) Check for a deteriorating / contaminated oxygen sensor, replace if necessary Check for inlet air leaks Check the MAF sensor for proper operation Replace the Bank 2 oxygen sensor upstream of the catalytic converter hope help.
