The present disclosure relates to diagnosing and locating fluid leakage within a pneumatic system () using a minimal amount of pressure sensors (). In general, each branch () of a pneumatic system () includes an associated pressure sensor () and in accordance with how the pneumatic components () associated with the pneumatic branch () are toggled and monitored, leaks can be detected and located within the branch () using a minimal amount of pressure sensors (). More specifically, pressure and pressure decay may be measured by the sensors () within a branch () while the pneumatic components () are in a particular configuration. The configuration is thereafter changed, and pressure and pressure decay are again measured by the sensors (). The results of these two measurements may enable the pneumatic system () to derive the presence and location of a leak.
