Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Erratic or fluctuating hydraulic pressure readings, or a complete loss of pressure signal, are the initial indicators. If ignored, this can lead to inconsistent hydraulic performance, potential component damage due to incorrect pressure, and system shutdown. Continued operation risks severe damage to the hydraulic system.

Installation Tip

Ensure the hydraulic system is properly depressurized before removing the old sensor to prevent injury and fluid loss. When installing the new sensor, use appropriate sealant on the threads if recommended, and tighten to the specified torque to avoid leaks or damage.

Service Note

Inspect the hydraulic fluid for contamination and check the hydraulic filter condition when replacing the high-pressure sensor.
