Where it lives

For P2DF9, the part to look at first is the pump named here.

Check these first

What to do next

1. Command coolant pump E on with a scan tool
2. Check the coolant pump E supply voltage
3. Inspect coolant pump E for debris or seizure
4. Check the coolant passage at pump E
5. Replace coolant pump E if it will not turn
