What P24A7 means
P24A7
EGR Cooler Coolant Pump Control Circuit/Open
Generic · emissions
Data confidence65%
The control module detected an interruption (open circuit) in the EGR Cooler Coolant Pump Control circuit, so the expected electrical continuity was not present.
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
Powertrain: engine, transmission and driveline systems.

Frequently asked questions about P24A7
What does P24A7 mean?
EGR Cooler Coolant Pump Control Circuit/Open. The control module detected an interruption (open circuit) in the EGR Cooler Coolant Pump Control circuit, so the expected electrical continuity was not present.
Is P24A7 generic or manufacturer-specific?
P24A7 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove P24A7 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.
