DEF Quality Sensors (DEFQS) failure can result in an engine torque derate in a variety of ways, including improperly or inappropriately detecting poor fluid quality in the diesel exhaust fluid tank, failing to communicate with the ECM, or being in a failed or offline condition.

The sensors, which measure the quality and level of diesel exhaust fluid (DEF) in the tank, normally retail for roughly $300.

The SCR system includes a DEF filter. For most DEF-equipped vehicles, this filter requires maintenance only if contaminants are in the DEF or if the vehicle reaches 300,000 miles.

Why is there a DEF Sensor Shortage? The pandemic caused factories to shut down worldwide, including factories that produce urea, rubber, and DEF sensor chips. The demand for urea, rubber, and chips have drastically increased due to trucks' sensors and chips failing.

A DEF quality sensor is mounted on the side of the DEF tank. This sensor detects the Urea concentration in the DEF to confirm it is acceptable for effective dosing (approximately 32.5% Urea).
