P2047 - REDUCTANT INJECTION VALVE CIRCUIT/OPEN BANK 1 UNIT 1

Description:  The powertrain control module (PCM) monitors the reductant injector circuits to the PCM for high and low voltage. The test fails if the voltage exceeds or falls below a calibrated limit for a calibrated amount of time.
Possible Causes: 
  • RDINJPWR circuit open or short
  • RDINJGND circuit open or short
  • Reductant injector open or short
Diagnostic Aids:  The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power.
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.
