OD light/brake light issues
OK guys i have a wiring problem on my 1992 f 250 7.3 idi e4od with factory tow package. if you drive down the road my od light comes on pull the codes and it says tps out of range an torque converter slippage. if you reset the computer and un hook the tail lights it wont do it for awhile. if you hook in my L.E.D headache rack lights it wont do it but it will glow dimly. there is 10.5 v at the trailer plug with the key on and all lights off all so if the tail light are unhooked and the L.E.D. are hook up the rear abs light comes on i have set the tps and replaced it. the tc is brand new and did it with the old tc. i put new brake light switch turn signal and cleaned every ground on the truck. Any ideas?

If you didn't hold the accelerator on the floor when running the engine off test you will get a TP out of range code.
The torque converter slip code is not always reliable. Sometimes it means the converter is bad, sometimes it is an erroneous code. If it happens once in a while you can probably ignore it. If you get it repeatedly you have a bad converter.
