The speedometer signal comes from the rear axle abs sensor. The PCM has nothing to do with it. You need to check the wiring from the rear axle to the abs computer.
Helo my name is erik, My truck is a 1992 f250 I have the same problem. I put in a new sensor and pigtail in rear and it still is not working. I have checked and removed and replaced fuses and still no go. I am going to check the wiring for continuity, and voltage. I pulled the speedo cluster out and checked it and the speedo worked for a while and quit again. I have a friend at fords and he thinks it is the wiring from the rear axle sensor to speedo or the speedometer itself. I am looking for a speedometer cluster to borrow to try that. Should be a diesel cluster. let me know if you get yours working and what you did. Thanks. Mail me at ehansen@cleaninter.net
