obd connection not working?
Need help here. I got a 2000 f150 with 4.2 liter v6 it has 226,000 miles on it. Last winter I had the heater core replaced, and noticed soon after that my connection on my obd under the dash no longer seems to work. I have tried two different scanners but neither one works, tried them on my Lincoln truck and both scanners worked. So I am wondering if anyone out there knows exactly where these wires come from. When looking under there, they snake around under the dash and I can't seem to keep track of it. Also, is there a way to test power to this obd connection? Is there one prong that should have power at all times? The service engine soon light is on and it has a miss sometimes but cant seem to locate exactly what it is. I am thinking the miss may be caused by a bad o2 sensor, but there are 4 of them on this truck and hate to replace all of them just to figure it out! Any and all help would be greatly appreciated, Thanks
