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 pressure readings on the operator's display are the first indication of a faulty sensor. If ignored, this can lead to incorrect hydraulic system adjustments, potentially causing sluggish or unresponsive implement controls. Continued operation with a faulty sensor risks improper system operation and potential damage to hydraulic components due to incorrect pressure management.

Installation Tip

Ensure the electrical connector is clean and free of corrosion before plugging it in. Avoid overtightening the sensor into the hydraulic port, as this can damage the threads or the sensor body.

Service Note

Inspect the hydraulic fluid for contamination and check related wiring and connectors for any signs of damage or wear.
