Engine Coolant Bypass Valve E Control Circuit High

Where it lives

For P2E64, the description names the valve as the part involved.

Check these first

• A short to voltage on the engine coolant bypass valve E control wire
• An open ground at the engine coolant bypass valve E
• A failed engine coolant bypass valve E actuator
• Corroded pins in the coolant bypass valve E connector
• A failed driver for circuit E inside the engine control module

What to do next

1. Read the engine coolant bypass valve E status on a scan tool
2. Command the bypass valve E through its full range
3. Test the bypass valve E control wire for a short to voltage
4. Check the bypass valve E ground circuit for continuity
5. Replace the coolant bypass valve E if the circuit tests good
6. Clear the code and retest
