SID 146 indicates that during engine operation, the PLD-MR received EGR system parameters outside their normal range resulting in one or more of the following fault codes:‪

  • EGR Temperature above Normal (146 00)
  • EGR Temperature below Normal (146 01)
  • Data Erratic (146 02)
  • EGR Valve not Responding (146 07)
  • Bad Component (146 12)
