I'm experiencing the same failure right now with the right front wheel speed sensor. Odometer and trip meter not working. so more research is needed.
The wheel speed (or ABS) sensors are:
2002-2006 Jeep Liberty - Anti-Lock Brakes Sensor, Right - Mopar (52128694AE)
2002-2007 Jeep Liberty - Anti-Lock Brakes Sensor, Left - Mopar (52128695AF)

ALSO: mopar.com lists wheel speed sensor 56028187AE for 2001-2005 Dodge trucks. Will it fit a KJ?
56041393AA is the rear axle wheel speed sensor for 2002-2006 Jeep Liberty (ref: '05 KJ fiche and mopar.com)
