Hey,
I have having those codes for 3500km will driving from Montreal to Edmonton. I have bought a 2001 Pathfinder LE 101,000km (3.5 VQ35DE). The SES went on, sow i purchased an OBD2, P0138 P0139 and P0140 showed up. From what i understand it is the rear right O2 sensor. Can you people help me locating the correct O2S, buying a new correct one and other stuff i should know.
thanks
