Code P0035 GMC Description
The P0035 diagnostic trouble code (DTC) for GMC vehicles specifically refers to an issue with the Turbocharger Bypass Solenoid Valve Control Circuit registering a high voltage. This code indicates that there is an electrical problem in the circuit that controls the turbocharger bypass solenoid valve. The turbocharger bypass solenoid valve is responsible for regulating the flow of exhaust gases to the turbocharger, which in turn affects the boost pressure and overall performance of the engine.
Common Causes of P0035 GMC
- Damaged wiring or connectors in the control circuit
- Faulty turbocharger bypass solenoid valve
- Issues with the engine control module (ECM)
- Malfunctioning turbocharger
- Corrosion or poor electrical connections
Symptoms of P0035 GMC
- Decreased engine performance
- Hesitation during acceleration
- Rough idling
- Engine stalling
- Check Engine Light illuminated on the dashboard
How to Fix P0035 GMC
- Begin by conducting a thorough visual inspection of the wiring and connectors in the turbocharger bypass solenoid valve control circuit.
- Test the turbocharger bypass solenoid valve and the control circuit using a multimeter to check for proper voltage levels and continuity.
- If the solenoid valve is faulty, replace it with a new one and ensure proper installation.
- Clear the DTC from the vehicle's ECM using a diagnostic scan tool and test drive the vehicle to confirm that the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any underlying issues with the ECM or turbocharger.
Cost to Fix P0035 GMC
The typical repair costs for addressing a P0035 code related to the turbocharger bypass solenoid valve control circuit high voltage can range from $200 to $500, including parts and labor. However, it's important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Auto repair shops commonly charge between $80 and $150 per hour for labor, with rates potentially higher in metropolitan areas or at dealerships, and lower at independent shops. It's advisable to obtain local estimates for a more accurate cost assessment.

What are common symptoms of the P0035 code on a GMC vehicle?
Symptoms include reduced engine performance, poor acceleration, turbo lag, excessive exhaust smoke, and possibly an illuminated check engine light.
What causes the P0035 code on a GMC?
Common causes include a faulty turbo bypass solenoid valve, damaged wiring or connectors in the circuit, or a malfunctioning engine control module (ECM).
Can a P0035 code cause engine damage if ignored?
Yes, prolonged driving with this code can lead to engine stress, overheating, or damage to the turbocharger due to improper pressure regulation.
How do I diagnose the P0035 code on a GMC?
Start by inspecting the turbo bypass solenoid valve, wiring, and connectors for damage. Use a multimeter to check for proper voltage and resistance in the circuit.
Can I drive my GMC with a P0035 code?
It is not recommended to drive with this code, as it can lead to poor engine performance and potential damage to the turbocharger or engine components.
How do I fix the P0035 code on my GMC?
Repairs may involve replacing the turbo bypass solenoid valve, repairing damaged wiring or connectors, or reprogramming the ECM if necessary.
How much does it cost to fix a P0035 code on a GMC?
Repair costs can range from $100 to $400, depending on whether the solenoid valve needs replacement or if wiring and ECM programming are required.
Can a dirty air filter cause the P0035 code?
While unlikely, a severely clogged air filter may contribute to turbocharger performance issues, but it’s not a direct cause of the P0035 code.
Does the P0035 code affect fuel economy?
Yes, this code can reduce fuel efficiency due to improper turbocharger operation and increased engine strain.
