What year for OBD1 to OBD2
What was the actual year they started putting OBD2's in the F-150's? My 95 puts out 2 digit codes and a guy I just got off the phone with said that's impossible because my truck has the OBD2 in it not the OBD1. I was told and the code reader for my truck is for a OBD1. Is there a way to truly tell.

1996 was the year mandated for all vehicles to have OBDII except for vehicles above 8300 GVWR (I think that is right). I would have thought your truck would have 3 digit output, but someone said here that it depends on your transmission, i.e. E4OD, AOD-E, 4R70W did have 3 digit codes manuals had 2 digit.

Mine is an auto with a 302, on my code scanner it's putting out 2 digit codes. Even when I took it to my brother-in-law at the Ford dealership it came up wityh a 2 digit code. I don't know which tranny I have, it's either an AOD-E or an 4R70W. It's hard to tell cause both had a 14 bolt pattern.

It's got nothing to do with the transmission.
If the test connector is under the hood behind the airbox it's OBD-I. If the connector is under the dash it's OBD-II. The switchover to three-digit codes was around the 90-92 time frame. A 1995 F-150 will be OBD-I and will give three digit codes.
