Turbocharger/Supercharger Bypass Valve B Control Circuit High

Where it lives

For P00C2, start at the valve the description names.

Check these first

• A short to power on the bypass valve B control wire
• An open in the valve B ground
• A valve B actuator with high resistance
• A corroded or wet valve B connector
• A faulty ECM driver stuck high

What to do next

1. Inspect the valve B connector for corrosion or water
2. Test the control wire for a short to battery voltage
3. Measure the valve B actuator resistance and look for an open
4. Check the valve B ground for continuity
5. Replace the bypass valve B actuator if the coil is open
6. Clear the code and retest
