P207F - REDUCTANT QUALITY PERFORMANCE

Description:  The PCM monitors selective catalytic reduction (SCR) system performance using the nitrogen oxide (NOx) sensor, in addition to other inputs. This DTC sets when overall NOx conversion drops suddenly.
Possible Causes: 
  • Poor reductant quality
  • Damaged SCR system components
  • Damaged SCR catalyst
  • Biased NOx sensor
Diagnostic Aids:  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.
