Does anyone have the correct code definitions for a 94 f350 with a powerstroke 7.3? I thought my list was the right one but it's for a gas engine. This one has the obd2 dlc under the dash but it doesn't do anything at all. It also has the eec-4 connector on the left fender and that is what I use. It gives out 3 digit codes. This morning my light came on for a few seconds and when I checked the memory there was a code 125 stored. I think that is for the idle validation switch but not sure.
The buzz test, contribution test and KOER test all ran normal.

Not sure on your code, but I am interested in how you get a buzz test...


BTW: I got my PCM flashed and the OBDII connector works now....

It comes at the end of the KOEO codes. After the last one is flashed just press the gas pedal to the floor and let it go then the buzz test will start. At the end of the test you can press the pedal again to redo it if you want. The second one will usually show a problem if there is one.

He's only got the OBD2 codes on there. He changed the pcm on his a long time ago so he didn't have to go through this mess. I know I need to do that but I can't afford it right now.
