Wrong or missing reading
A failed sensor gives a dead or false gauge reading or a warning light.
Fault codes
Check the wiring and plug first; if the sensor itself reads out of range, replace it.
Corrosion
Connectors on machines take water and dirt. A corroded sensor is cheaper to replace than to chase.
Fleet spares
Common sensors are worth keeping in stock for each machine type.
