309-5795 Pressure Sensor — Cat C13 313B

This Pressure Sensor is an electronic device that measures and transmits hydraulic or oil pressure readings to the machine's control system. Manufactured to precise specifications, it ensures accurate and reliable pressure data, unlike a faulty sensor that provides erratic or incorrect readings, which can lead to improper system operation. Operators may observe erratic hydraulic system performance, incorrect gauge readings, or trigger diagnostic trouble codes (DTCs) related to pressure when this sensor fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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

Failure Symptoms

The initial symptom of a failing pressure sensor is often an inaccurate reading on the machine's pressure gauge or an illuminated warning light. If ignored, this can lead to the machine's control system making incorrect adjustments, potentially causing sluggish hydraulics or over-pressurization. Continued operation with incorrect pressure data risks damage to hydraulic components or the engine.

Installation Tip

Before installation, ensure the port threads are clean and free of debris; apply thread sealant sparingly if recommended by the manufacturer. Avoid using excessive force when tightening the sensor, as this can damage the threads or the sensor body.

Service Note

Inspect the hydraulic lines, fittings, and related control valves for leaks or blockages when replacing the pressure sensor.
