274-6720 Oil Pressure Sensor — Cat 320D

This oil pressure sensor is a vital instrument that monitors the engine's lubricating oil pressure and transmits this information to the operator or engine control module. Manufactured to precise standards, it offers accurate readings and reliable performance, unlike worn sensors that provide false or no data. Operators may observe an inaccurate or fluctuating oil pressure gauge reading, or an engine warning light illumination when this sensor begins to fail.

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 first indication of a faulty oil pressure sensor is often an erratic or incorrect reading on the engine's oil pressure gauge, or the illumination of the oil pressure warning light. If the sensor fails completely, the gauge may read zero or maximum, or the warning light may stay on constantly. Continued operation without accurate oil pressure monitoring risks severe engine damage due to insufficient lubrication.

Installation Tip

Ensure the engine is cool and the oil pressure is relieved before removing the old sensor to prevent oil spillage. Apply a small amount of thread sealant to the threads of the new sensor, avoiding the sensor's electrical connection.

Service Note

Check the engine oil level and condition, and inspect the oil filter for clogging when replacing the oil pressure sensor.
