This exhaust fluid level sensor monitors the AdBlue (Diesel Exhaust Fluid - DEF) level in the vehicle's tank, ensuring the emissions control system has sufficient fluid to operate correctly. It provides accurate readings to the engine control module, preventing system deactivation due to low DEF levels, and differs from a faulty sensor by reliably indicating the true fluid quantity. Operators may see a low DEF warning light, reduced engine power, or the vehicle refusing to start if this sensor fails to detect adequate fluid levels.

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.
The first indication of a faulty exhaust fluid level sensor is typically a persistent low DEF warning light, even after refilling the tank. If the sensor fails completely, the vehicle's emissions system may not function, leading to reduced engine power or the inability to restart the engine after shutdown. This is a critical safety and regulatory feature designed to ensure compliance with emissions standards.
Ensure the DEF tank is clean and free of any contaminants before installing the new sensor to prevent premature failure. Avoid forcing the sensor into place; it should seat smoothly into its mounting location.
Inspect the DEF tank for any signs of leaks or damage, and ensure the DEF fluid is of the correct specification when replacing the level sensor.
