1112302-002 Diesel Exhaust Fluid Level Sensor — Cat

This is a high-precision Diesel Exhaust Fluid (DEF) level sensor, crucial for monitoring the DEF tank contents in modern emissions systems. Manufactured to meet exacting OEM specifications, it provides accurate readings that a faulty sensor cannot, preventing false alarms or system shutdowns. Operators may observe a 'DEF level low' warning light, reduced engine power, or even a no-start condition if the sensor fails to report the correct fluid level.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

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 DEF level sensor is often an inaccurate display of the DEF fluid level, or a 'DEF level low' warning when the tank is full. If ignored, the engine control module may interpret this as a critical emissions fault, leading to engine derating or a shutdown timer. The ultimate consequence is the inability to operate the equipment until the emissions system fault is rectified.

Installation Tip

Ensure the DEF tank is clean and free of debris before installing the new sensor to prevent immediate contamination. Do not force the sensor into place; it should seat smoothly.

Service Note

When replacing the DEF level sensor, it is advisable to inspect the DEF pump and filter for any signs of contamination.
