speedometor

[TheDarkAngel]

so everything is working but my speedometor recently stoped working, i checked all the fueses and they all seem good. is there any other reason why it may not be working?

When my speedometer stopped working it was because the sensor in the differential was covered with metal shavings....pull out the sensor (2 x 10mm bolts) and see if it is covered in crap...

Check your OBC and see if it will calculate time to distance or other speed related functions like avergae speed. If those functions do work, but your speedo still isn't working, your problem is most likely with the speedo its self. If not, chances are, your having a problem with the speed sensor in the diffo.


You might try to unplug the connector, spray it down with contact cleaner, and plug it back in first. You may just have dirty contacts in the connector or on the sensor its self. If that doesn't slove the problem, you'll have to remove the sensor, and check it out directly for problems. The wiring from the sensor may be faulty as well.

Good luck.

so i got a new cluster gauge and the speedometer still doesnt work. is there anything that may have come unpluged from the rear axel because some times when im driving the speedometer will jump up really quick and then drop
