Other Sensors & Valves encompass a diverse range of components monitoring and controlling vehicle systems beyond primary engine or chassis functions. These parts are found throughout the vehicle, including HVAC, fuel/vapor systems, lighting, and interior comfort features. Functionally, they provide data to control modules for system optimization, or directly actuate valves for fluid/air regulation. Technical features include specialized material construction for fluid compatibility, precise calibration for accurate readings, and robust electrical connections for reliable signaling. Common examples include fuel tank pressure sensors, evap system purge valves, and cooling fan speed sensors. Failure typically manifests as system malfunction or diagnostic trouble codes related to the monitored circuit.
