What P24F2 means

P24F2
EGR Temperature/Charge Air Cooler Temperature Correlation Generic · emissions Data confidence 65%

The control module detected a fault associated with the EGR Temperature/Charge Air Cooler Temperature Correlation circuit or function; the stored code identifies the affected component rather than a single failure mode.

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

Frequently asked questions about P24F2

What does P24F2 mean?

EGR Temperature/Charge Air Cooler Temperature Correlation. The control module detected a fault associated with the EGR Temperature/Charge Air Cooler Temperature Correlation circuit or function; the stored code identifies the affected component rather than a single failure mode.

Is P24F2 generic or manufacturer-specific?

P24F2 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove P24F2 at file level?

If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
