This code means there's a problem with the part of the car that helps cool down the engine's exhaust gases. It's like a fan that isn't working right, and the car's computer noticed it.
The P24D4 code is triggered when the Engine Control Module (ECM) detects an issue with the feedback circuit of the EGR cooler coolant pump. This pump is responsible for circulating coolant to cool down the exhaust gases before they re-enter the engine.
The Exhaust Gas Recirculation (EGR) cooler coolant pump is an essential component that helps reduce emissions by cooling the recirculated exhaust gases. The feedback circuit provides data to the ECM about the pump's operation. If the ECM detects an abnormal signal or lack of feedback from this circuit, it triggers the P24D4 code.
• Check Engine Light is on
• Reduced engine performance
• Increased emissions
• Faulty EGR cooler coolant pump
• Damaged wiring or connectors in the feedback circuit
• Failed ECM or software issue
EGR: Exhaust Gas Recirculation
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the EGR cooler coolant pump for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the EGR cooler coolant pump if faulty.
• Update or reprogram the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Ram 1500
• Regular maintenance checks
• Ensure coolant levels are adequate
• Inspect wiring and connectors periodically
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid driving extensively until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code is relatively uncommon and typically occurs in vehicles with higher mileage or inadequate maintenance.
Moderate – It should be addressed soon to prevent increased emissions and potential engine damage.
Driving with a malfunctioning EGR system can result in higher emissions, which may not comply with local laws.
• Engine at normal operating temperature
• Vehicle stationary or at idle
The EGR cooler coolant pump is typically located near the EGR cooler, which is connected to the exhaust system.
Q: Can I drive with a P24D4 code?
A: It's not recommended to drive for extended periods as it can lead to increased emissions and potential engine damage.
Q: How can I reset the Check Engine Light?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is resolved, the light should stay off.
