| Diagnostic Aids:
The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power. The reductant level sensor and reductant temperature sensor share a common ground. An open or short to voltage in this ground sets DTCs for both sensors. After repair, the vehicle may still display a reductant system warning message. Drive the vehicle until the reductant system warning message has cleared from the instrument cluster message center. |
