You know we need more details than that. What were the fault codes? Do you really think three sensors failed all at once? Fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. In this case, if all the fault codes were related you need to look at what those circuits have in common. Corroded connector pins and rubbed-through wires are common causes of fault codes.
