This is a DEF (Diesel Exhaust Fluid) level sensor, crucial for monitoring the amount of DEF in the tank for modern Volvo trucks. Built to OEM specifications, it ensures accurate fluid level readings, unlike a worn sensor that might provide false data. Observable symptoms of a failing sensor include incorrect DEF level indications on the dashboard, DEF system warning lights, or the vehicle entering a reduced power mode.

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 operator may first notice an inaccurate DEF level displayed on the dashboard or a DEF system warning light. If ignored, the system may trigger a countdown to engine shutdown or a severe power reduction to enforce emissions compliance.

Installation Tip

Ensure the DEF tank is clean and free of debris before installation to prevent contamination of the new sensor. Do not force the sensor into its mounting bracket; it should seat smoothly.

Service Note

Inspect the DEF tank for any signs of leaks or internal contamination, and check the DEF fluid quality.
