Help GUYS! driving down the interstate in my 01 6 speed. hear a ding look down speedometer is jumping between 30 and 40 then quits as brake and ABS light comes on. my fuel gauge quit long ago but all other gauges are working fine still. any ideas? i have had all gauges quit before and flash "no bus" on odometer but investigation found a loose wire block in electric block under hood. check all that and it looked fine to me no improvement or difference. any help or input much appreciated!

 

Rear axle speed sensor, my guess offhand.

 

Yep , what Jim said . That happened to me too. Pretty cheap part and easy to install.

 

X3, but don't hesitate the pick up sensor can damage the toothed wheel if it comes apart.
