FORD SUPER DUTY P0155 P0135 WIRING SHORT
I just wanted to share with you guys my experience with this 2014 Ford F-550 SUPER DUTY pickup truck with a 6.8L V10 engine. It came in with a check engine light and codes for oxygen sensor bank 2 sensor 1 heater circuit. There was also a code stored for the a/c pressure switch. After replacing the air fuel ratio sensor (AFR) the problem was still there. So, I had to trace a short in the wiring harness and this is what I found. I hope this video helps someone with the same problem.
