P24D4
EGR Cooler Coolant Pump Feedback Circuit Generic · emissions Data confidence 65%

The control module detected improper operation of the EGR Cooler Coolant Pump Feedback circuit.

Symptoms

  • MIL illuminated
  • Possible reduced engine performance
  • Possible rough idle or hesitation

Possible causes

  • Carbon-blocked EGR passages
  • Sticking or slow EGR valve
  • EGR actuator or position sensor fault
  • Wiring or connector fault
  • Vacuum supply fault (vacuum-operated systems)

Recommended checks

  • Read freeze frame data and full module scan
  • Check battery voltage and sensor supply
  • Inspect EGR wiring and connectors
  • Compare commanded vs actual EGR position/flow with live data
  • Inspect EGR valve and passages for carbon build-up
  • Check related vacuum lines where fitted
