Multiquip 8980274560 Pressure Sensor 4HK1 - OEM Replacement Part

This pressure sensor monitors oil pressure in the 4HK1 engine, providing critical data to the microprocessor engine controller (MPEC) to prevent engine damage from low oil pressure conditions. When oil pressure drops below safe operating levels, this sensor triggers the low oil pressure warning light on the generator control panel and can initiate automatic engine shutdown to protect internal components.

The sensor integrates directly with the engine wiring system and MPEC unit on DCA70USI generators. According to Multiquip troubleshooting procedures, a failed oil pressure sending unit is a common cause of persistent low oil pressure lights even when oil levels are correct. Regular inspection during the 250-hour maintenance interval helps identify sensor degradation before failure occurs. The sensor connects to the engine controller's monitoring system, which uses time-delay functions to distinguish between momentary pressure drops during startup and genuine low-pressure conditions requiring intervention.

Compatible with the following Multiquip models:

• DCA70USI3CAN
• MQP56
