EGR Cooler Coolant Pump Performance/Stuck Off

Where it lives

For P24A8, start at the pump the description names.

Check these first

• A coolant pump that is stuck and will not turn
• Low coolant level or air in the EGR cooler circuit
• A failed pump relay or control circuit
• A pump that turns but moves too little coolant

What to do next

1. Check the coolant level and bleed air from the EGR cooler circuit
2. Command the coolant pump with a scan tool and listen for it
3. Check the pump feed and ground for voltage and high resistance
4. Test the pump relay and its control signal
5. Replace the coolant pump if it will not run or move enough flow
6. Clear the code and retest
