Volvo All Engines (2017 Emissions) Fault Code: P206C00 PID: ACM Reductant Quality Sensor Low

Volvo All Engines (2017 Emissions) Fault Code: P206C00 PID: ACM Reductant Quality Sensor Low

Circuit description
The DEF quality, level, and temperature sensor detects the concentration of fluid in the DEF tank. The sensor is connected to the DL7 data link which sends a signal to the Aftertreatment Control Module (ACM) and Engine Control Module (ECM). The relevant control module interprets the information and activates a lamp in the instrument cluster, inducement mode or both if necessary

Probable cause
1) Short circuit in component
2) Internal fault in component
