P00C0 Code - Turbocharger Bypass Solenoid Valve Control Circuit 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 P00C0 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 an open circuit condition of the turbocharger bypass solenoid valve control circuit bank 2 for greater than 6 s.
What are the Possible Causes of the DTC P00C0?
- 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)
How to Fix the DTC P00C0?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P00C0 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P00C0 Code
1. What does the OBDII code P00C0 mean?
P00C0 indicates an issue with the Turbocharger Bypass Solenoid Valve Control Circuit in Bank 2, meaning the circuit isn’t functioning as expected.
2. What are the common symptoms of the P00C0 code?
Symptoms may include reduced engine performance, poor acceleration, turbo lag, decreased fuel efficiency, and the check engine light being illuminated.
3. What causes the P00C0 code to appear?
Common causes include a faulty turbocharger bypass solenoid valve, damaged wiring or connectors in the control circuit, or issues with the engine control module (ECM).
4. Can I drive my car with the P00C0 code?
While you may still be able to drive, it’s not recommended as it can lead to further damage to the turbocharger system or reduced performance and efficiency.
5. How is the P00C0 code diagnosed?
A technician will typically inspect the wiring and connectors, test the bypass solenoid valve, and use a scan tool to monitor the performance of the circuit in Bank 2.
6. What repairs can fix the P00C0 code?
Repairs may include replacing the turbocharger bypass solenoid valve, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
7. Is the P00C0 code specific to certain car brands?
No, P00C0 is a generic powertrain code applicable to OBDII-equipped vehicles, but the troubleshooting and repair process may vary by manufacturer.
8. How much does it cost to fix the P00C0 code?
Repair costs depend on the root cause but can range from $100 for electrical repairs to $500 or more if a new solenoid valve or ECM is required.
9. Can a dirty air filter cause the P00C0 code?
A dirty air filter is unlikely to directly cause P00C0, but it can affect overall turbocharger performance, potentially contributing to related issues.
10. How can I prevent the P00C0 code from recurring?
Regular maintenance, including inspecting the turbocharger system and electrical connections, can help prevent issues with the bypass solenoid valve circuit.
