My 00' Mamima LE has been diagnosed with DTC codes of PO138, PO139. I've can't find any info from the FAQ's or search posts section of this website. can anyone help me with this problem: i need to replace the two parts and am curious if $228.00 is a fair price for the parts and is it a job i can do myself or leave it up to the experts?

thanks

Once you've replaced the two rear 02-sensors, you need the dealer to reprogram the ECU.
