239-3478-2393478 Pressure Sensor 239 3478 — Cat C11 C13

This pressure sensor monitors and transmits critical hydraulic or engine oil pressure data to the machine's control system, ensuring optimal operation and protection. Manufactured to meet precise OEM specifications, it provides accurate readings, unlike a faulty sensor that may give erratic or incorrect data. Operators might observe warning lights on the dash, erratic gauge readings, or the machine entering a reduced power mode when this pressure 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

A failing pressure sensor can initially cause intermittent warning lights or inaccurate readings on the operator's display. If left unaddressed, the incorrect data may lead to the engine control module making improper adjustments, potentially causing performance issues or system shutdowns. Continued operation with a faulty sensor risks undetected pressure problems that could damage critical engine or hydraulic components.

Installation Tip

Ensure the threaded port is clean and free of debris before installing the new sensor to guarantee a proper seal. Avoid using excessive force when tightening the sensor, as this can damage the threads or the sensor housing.

Service Note

Inspect the wiring harness and related system components, such as the oil pump or filter, when replacing a pressure sensor.
