Hi Guys, Im new to the Honda world. Picked up a 2000 CR-V for the wife last week and now i have 2 codes, as stated in the title p0131/p0171. I am assuming that this means i have a bad upstream 02 sensor... But before i did anything i wanted to ask people that have experience in the Honda field.
Any help will be greatly appriciated, Thanks in advance !!!

 

Replace the primary O2 sensor with a Denso/NTK unit. Stay away from Bosch.
