When you say, "all the sensors", my question is WHY? There is no reason to change all the sensors on this vehicle, which would cost plenty. You are talking about multiple sensors here and that is never done. Only replace the one that is defective. I think you need to take this vehicle to a professional before you throw money at a problem without knowing what to replace. You will be money ahead by only repairing what needs repairing.
