This DEF level sensor accurately monitors the amount of Diesel Exhaust Fluid (DEF) in the vehicle's tank, ensuring proper operation of the selective catalytic reduction (SCR) system. Manufactured to meet stringent OEM quality, it provides reliable readings compared to a worn sensor that may give false low or high indications. Operators may notice DEF system warning lights, reduced engine power, or even an inability to restart the engine if this 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 first sign of a problem is often a DEF level warning light on the dashboard, or an inaccurate display of the DEF level. If the sensor fails completely, the system may not know if DEF is present, leading to engine derating or shutdown to comply with emissions regulations. Continued operation with a faulty sensor can result in non-compliance with emissions standards and potential vehicle immobilization.

Installation Tip

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

Service Note

Inspect the DEF tank for any signs of leaks or internal damage, and check the electrical connector for corrosion or loose pins.
