My entourage has the check engine light on as well as the abs light and the cruise does not work, I have a scanner and got code p0501 which is speed sensor issue , After doing some reading it seems all three problems could be related does anyone know where the sensor is located so I could have a look at it and see if it needs replacing

 

i would check the right front wheel speed sensor. it is mounted on the spindle. look for anything obvious. ie: unplugged connector, damaged harness...
