What Does This Pressure Sensor Do?
Measures hydraulic, fuel, or oil pressure at a specific point in the system and reports the live value to the control unit. Used to monitor system health and trigger alarms or automatic shutdowns if pressure drops outside safe operating limits.
Possible Pressure Sensor Problem Symptoms
If your machine is showing any of the following, a faulty pressure sensor may be the cause:
- Pressure warning light or fault code showing on the instrument panel
- Erratic or zero pressure reading on the gauge display
- Unexpected machine shutdown during normal operation under load
- Reduced hydraulic force or fuel system performance
