P0500 vehicle speed sensor
So I recently replaced my 4406 transfer case with another 4406. Shortly after the replacement (say 1000 miles) my speedometer and cruise control stopped working. I figured that the VSS in the tail housing of the 4406 went out. Because my Mountaineer is a 1997 my VSS is in the tail housing of the transfer case, not in the rear differential, just like the original transfer case for this year. I do have a sensor in the rear diff but it is strictly for the rear anti-lock brakes. The ABS light is not on. A few days, maybe as long as 2 weeks later I got a check engine light, I figured I knew it was going to be something to do with the VSS. It did surprise me that the check engine light didn’t come on for days though. So after several weeks of using my Ultra Gauge for a speedometer (it uses the output shaft speed sensor in the transmission) I decided it was time to replace the VSS. I took the spare I have from my old transfer case and installed it. WTF! It didn’t work! I just ran the code reader to read my trouble code, big surprise P0500 Vehicle Speed Sensor.
So I am thinking I probably routed a cable somewhere and it chaffed thru or shorted. That will likely be one of the first areas I will look at.
What I am looking for is any advice, procedures, schematics or explanations of the routing of the connections between the VSS and the ECU. Any electrical tests I can do to make sure the VSS is working (put power here, hook oscilloscope up here and rotate). Check to make sure power is where it is supposed to be at the VSS connector. Stuff like that.
Thanks,
Dan
