P00C2 GMC Code - Turbocharger Bypass Solenoid Valve Control Circuit High Voltage Bank 2
Quick Answer
Each of the turbochargers is provided with a vacuum-operated bypass valve, which opens during abruptly closed throttle conditions, to prevent turbocharger surging and damage from vibrations. Common causes include Faulty Turbocharger Bypass Solenoid Valve, Turbocharger Bypass Solenoid Valve harness is open or shorted, Turbocharger Bypass Solenoid Valve circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P00C2 GMC Description
As engine load and engine speed increase, the turbocharger bypass solenoid valves are commanded ON by the ECM. As soon as the throttle closes the turbocharger bypass solenoid valves are commanded OFF by the ECM to allow the bypass valves to open and allow the turbocharger air to recirculate to prevent surging.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects a short to voltage on the turbocharger bypass solenoid valve control circuit bank 2 for greater than 6 s.
What are the Possible Causes of the DTC P00C2 GMC?
- Faulty Turbocharger Bypass Solenoid Valve
- Turbocharger Bypass Solenoid Valve harness is open or shorted
- Turbocharger Bypass Solenoid Valve circuit poor electrical connection
- Faulty Engine Control Module (ECM)
