replaced output speed sensor due to code PO720 .

What is your question?

engine light went out for few minutes then van started doing same thing ,speedometor started jumping from 0 to 20 and the van would hesitate or slightly jump. Sometimes when starting from a stop the van would seem like to wants to stall out for a fast moment. I had the problem and it was the same code that said it was the speed sensor. Can't figure it out. Kind of hear a slight whining noise now also.

What makes this problem better or worse?

the more we use it it kind of jurks when at a stop to start

How long has your 2003 Dodge Grand Caravan had this problem?
