Also, are the sensors located outside of the drum or inside of the drum? My husband is going to take a wheel off and try to get to it and clean them to see if that will fix the problem. The photo that we saw from someone's link showed it inside the drum, but the autozone diagram makes it look like it is outside of the drum.
Thanks!

The sensor fits inside the drum but it is accessed from outside at the back of the backing plate. I think it is towards the rear of the wheel. If you drive the van up on ramps they are easily seen by following the electrical wire. Before removing them try following the wire to the connectors under the vehicle. Measure the resistance with an ohmmeter. It should read about 2000 ohms (I think). My faulty sensor was an open circuit.
