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.
An initial sign of failure may be intermittent or inaccurate hydraulic system pressure readings. If left unaddressed, this can lead to inconsistent machine performance and potential damage to hydraulic components due to incorrect pressure regulation. The ultimate risk is reduced operational efficiency and increased wear on the hydraulic system.
Ensure the electrical connector is clean and free of corrosion before plugging it in. Avoid overtightening the sensor into the port, as this can damage the threads or the sensor body.
Inspect hydraulic fluid levels and check for any signs of leaks in the hydraulic system when replacing this sensor.
