Hey guys, so last night I was coming home and my speedometer quit working and my park brake indicator light came on (no abs light). Now normally this problem is because of the abs sensor on the diff but I changed it 4 months ago because my speedometer didn't work when I bought the truck. My speedometer fluctuates between 0 and 20km/h no matter what speed I am going and I am pulling up no codes. Any ideas?

 

Speedo is driven from the sensor in the rear diff. So, either your sensor failed, or, you have wiring issues. Any warranty on the sensor? What brand did you get?

 

I have a Dorman abs sensor from summit racing.

See if you can find a standard motor products, delphi, denso, or mopar sensor.

 

Is there a possible fuse that could relate to my problem?

 

Just check ALL the fuses . But I also suspect you need a better brand sensor. And disconnect the negative battery cable when you replace it.
