I had a whole list of codes for b1s1 on my vehicle. I found that the plug was chewed up at the harness and three wires were shorted out. I replaced the plug now I'm getting a P0135 code. I have a wiring diagram but need a PCM pinout diagram to try to further diagnose the issue.

P0135 code indicating the O2 sensor heater circuit bank 1 sensor 1 O2 sensor which is common just replace the sensor. Also, here are the pinouts for the PCM as you requested. Check out the images (below). Please let us know if you need anything else to get the problem fixed.

Thanks, I'll try swapping out the o2 sensor. However, the PCM pin is different on my Explorer. I have the 3.5l Eco boost if that makes a difference. It's a 198 pin style and the PCM looks like the attached picture.

Thank you so much for the pin out. You were correct that it ended up being a bad o2 sensor as well. I just assumed the worst after having chewed up wires I guess lol. Thank you again for all of your help.
