You're not going to go to the auto parts store and buy a high fuel economy version of any sensor. Generally, the thing to do is replace broken sensors, then tell the computer lies by adding resistors, toggle switches, etc. as appropriate to make the computer think it's time to inject less fuel. But if you don't know anything about a certain sensor and how your ECU responds to it, I don't recommend messing with it.
