Typical Symptoms When the Sensor Fails

Pressure reading is unstable / out of range

Abnormal hydraulic response due to incorrect pressure feedback

Intermittent faults caused by connector pin corrosion or harness damage

Quick Troubleshooting (Field-Style)

1. Inspect connector pins and harness routing (oil ingress, corrosion, chafing).

2. Confirm power supply/ground integrity and check signal stability under load.

3. Compare sensor reading with a mechanical gauge if available to rule out real pressure issues.

Installation Notes

- Depressurize the hydraulic circuit before removal.

- Clean the port and replace sealing O-rings as required.

- Tighten to OEM torque specification and perform a leak check after installation.

Commonly Replaced Together (Optional)

Depending on machine configuration, the pressure sensor wiring harness and sealing O-rings may be replaced together during service.
