2001 Dodge Caravan Speedometer
Hey guys, I need some help please. I have a 2001 Dodge Caravan SE 2.4L and my speedometer doesn’t work. The other gauges work fine so I assumed it was just a dead speedometer motor or something so I picked up a used whole instrument cluster up at a junkyard, swapped them out and same problem. So I returned the replacement cluster already then I learned these vans how their own diagnostic test on the cluster so I did it, held down the trip/odometer button on the cluster and the following happened: all of the gauges including the speedometer cycles through their test, all of them worked, speedometer moved through its positions. And the following codes came up
Sof 4.0
100.4
100.5
100.6
E Code End
At this point I’m not sure where to go from this, I’ve been talking to chatGPT even bought the premium because I thought we were close with the multimeter tests but in the end it just acted dumb. I don’t know too much about electrical but we found the 12V female pinhole and 2 grounds on the harness that plugs into the cluster if that helps anybody at all.
Thanks in advance if anybody can help out!
EDIT: Forgot to add that I hooked up an OBD2 and tracked live data while driving and the OBD tool showed my MPH on it.
