| Post subject: | rear differential speed sensor |
Good day people. Hopefully there's someone here that can help me. 6 Months ago my speedometer stopped working, brake light + ABS light came on. (2004 Jeep Liberty KJ 2.8 CRD) I replaced my rear differential speed sensor (MOPAR 56041393AA) and all was back to normal again. Same happened to me bout a week ago, changed the sensor, but this time nothing changed. Speedometer not working, brake light & abs light on. So I went and changed the wiring to the sensor incld the plug, but still no change. I've multi-meter tested the Yellow wire and it receives 11v. Jacked up the rear, Tested the Yellow/Blue wire while spinning he rear wheel, it jumps to 1.5v (only cause I can't spin the wheel fast enough while holding the multi-meter) Last resort will be to go see the stealers Any help or input how to solve this will be much appreciated. Thank you. |

Thank you. There's a known wiring issue that will cause an intermittent issue with the rear sensor. The fox is to replace with larger gauge wire. I'll post a link of what I used when I have more time. Mike |

There is a Mopar wiring kit? Mine is doing similar, no odometer, temp readouts squirrly; ABS/Brake light on. It was intermittent for months now it's stuck. Not sure if it's wiring or the sensor yet. |
