Anybody ever replaced the O2 sensor on their 3.5 ecoboost? I'm getting a P0151 code which is the bank 2 sensor 1 O2 sensor. From what I can tell it is the sensor coming out of the exhaust manifold in front of the CAT. If that is the correct one, I can get to the sensor easy enough, but the connection to the wiring harness is located above the transmission and I can't seem to find an easy way to get to it. Any suggestions?
