This is a level sensor designed to monitor the fluid level within the Diesel Exhaust Fluid (DEF) tank on Volvo equipment. It is built to meet rigorous OEM quality standards, providing accurate readings unlike a faulty sensor that may indicate an incorrect fluid level. Operators might observe inaccurate DEF level displays on the instrument panel, or potentially receive false warnings about low DEF fluid.

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 most immediate symptom is an inaccurate or fluctuating DEF level displayed on the dashboard. If ignored, the system may trigger a low DEF warning, potentially leading to engine derate or shutdown to comply with emissions regulations. This can result in unexpected downtime and inability to operate the vehicle.
Ensure the new sensor's sealing O-ring is properly seated and lubricated to prevent leaks. Avoid forcing the sensor into the tank opening if it does not align easily.
Inspect the DEF tank for any signs of contamination or sediment, and check the DEF injector system for proper operation when replacing the level sensor.
