Just wondering how to pull codes for checking the trans in a 1991 frod e250 with a e4od and a 7.3. Just replaced the IP, and also the TPS. Now the OD light wants to flash all the time. Pull the cables wait 5 mins put them back on. Soon as you start it up it flashs.
Thanks

Get the code ready from Wally World, worth the $35. You can use it to clear the codes as well.

 

When you replaced the TPS/FIPL did you reset it to specs.......

To set to specs:
With a warm engine and the idle speed set to your engine specs probably 650 in drive (curb idle).

Now with key on engine off. First connect the negative lead of a volt meter to the negative battery post, then place a paperclip straightened to slide up the side of the center wire for a good contact, touch the positive lead to the paperclip. Electrical connector must beconnected to the FIPL.

If your FIPL requires resetting loosen the small torx screws and attempt to attain the correct setting. You can loosen the large bolts on the bracket if necessary but try to retain the centering on the FIPL/blade.

Your trying to get closed throttle voltage: 1.1 V, wide open throttle voltage: minimum of 3.8 V but not more than 4.3 V.

If you can attain those #s then tighten the screws/bolts and ensure the voltage is at the correct setting after tightening. You can also do a slow sweep of the fuel lever from idle to WOT to see if there are any blanc (dead) spots, much easier with a really $$$ meter with capture mode. If you still find there are hard shifts or very soft slippery shifts you can adjust to suit your driving but be warned slippery shifts will burn the trans up.

 

Well the TPS is sat at 1.09/4.05. I want to be able to get the codes with out have to make a trip to walmart. I just figured I can get teh codes then check to see what is bad. For 35 I could buy a VSS instead if its needed or a tach sender. The speedo and tach work no problems there. I rember pulling codes on my chevys but I am in the dark on this ford.
Thanks again

As far as I know these aren't built like the 80's cars where you just short out a couple of terminals or turn the ignition switch off/on to get the codes. Could be wrong, but I haven't read yet where it could be done.
A cheap code reader can make life easier.

 

Well I done some looking and found a site. Yeap they still can be pulled the old way. This site has almost every make listed and codes for them. It really great place. Here is a link to the ford codes and how to pull them.

Just curious, is the EEC plug in the same spot as a '94 F350?
For a look at where that EEC plug is and how to pull codes on a 94, check my gallery. I have some pictures of how I pull the codes from that year of truck.

I noticed that if I do NOT use the trip meter (94 has digital odometer) I have no OD flashign issues.
I just have not had time to look into that issue yet.
