i checked the speed sensor wires to the transmission and they read 8.53 ohms with the motor off with the motor running i could not read any D.C volts to the sensor but im not sure if i am supposed to with it at idle or if the voltage is generated with the van moving the wires go back to the vehicle control module one wire is signal the other wire is return...do you know if voltage is supposed to always be present...?

Its more likely going to be a problem with a wheel sensor or the ABS unit. Since the light is on, it needs to be scanned to retrieve the trouble code the computer has stored. Get the code and get back to me and we will go from there
