Code P0265 2017 Chevrolet Silverado Description
The P0265 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates an issue with the Cylinder 2 Injector Control Circuit having high voltage. This means that the fuel injector for cylinder 2 is receiving a higher voltage than normal, which can lead to fuel delivery problems and impact the engine's performance. The fuel injector is responsible for delivering the precise amount of fuel into the combustion chamber at the right time. When the voltage is too high, it can cause the injector to deliver too much fuel, leading to a rich air-fuel mixture and potentially affecting engine combustion efficiency.
Common Causes of P0265 2017 Chevrolet Silverado
- Faulty fuel injector for cylinder 2
- Wiring issues such as short circuits or open circuits in the injector control circuit
- ECU (Engine Control Unit) malfunction
- Corrosion or poor connections in the wiring harness
- Fuel pressure regulator malfunction causing high fuel pressure
Symptoms of P0265 2017 Chevrolet Silverado
- Engine misfires or hesitation during acceleration
- Rough idling or stalling
- Decreased fuel efficiency
- Check Engine Light illuminated on the dashboard
- Strong fuel odor from the exhaust
How to Fix P0265 2017 Chevrolet Silverado
- Begin by inspecting the wiring harness and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Check the fuel injector for cylinder 2 to ensure it is functioning correctly. Replace the injector if it is faulty.
- Test the ECU to determine if it is sending the correct voltage signals to the fuel injector. Replace the ECU if necessary.
- Verify the fuel pressure regulator is functioning within specifications. Replace if it is causing high fuel pressure.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0265 2017 Chevrolet Silverado

Frequently Asked Questions about P0265 2017 Chevrolet Silverado Code
What does the OBDII code P0265 mean on a 2017 Chevrolet Silverado?
P0265 indicates a "Cylinder 2 Injector Control Circuit High Voltage," meaning the fuel injector's electrical circuit for cylinder 2 is experiencing higher-than-expected voltage.
What are the common symptoms of code P0265?
Symptoms may include rough idling, engine misfires, reduced fuel efficiency, hesitation during acceleration, and an illuminated check engine light.
What causes the P0265 code to appear?
Common causes include a faulty fuel injector, damaged wiring or connectors in the injector circuit, a malfunctioning powertrain control module (PCM), or short circuits in the wiring harness.
Can I drive my 2017 Chevrolet Silverado with the P0265 code?
Driving with this code is not recommended, as it can lead to poor engine performance, increased emissions, and potential damage to other engine components.
How do I diagnose the P0265 code?
Start by inspecting the wiring and connectors for cylinder 2's fuel injector for damage or corrosion. Use a multimeter to check for proper voltage and resistance in the circuit, and test the injector itself.
What repairs typically fix the P0265 code?
Repairs may involve replacing the faulty fuel injector, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the PCM if it's determined to be faulty.
How much does it cost to fix the P0265 code?
Repair costs can vary widely. Replacing a fuel injector typically costs $200–$400, while wiring repairs may cost $50–$200. PCM replacement or reprogramming can cost $500 or more.
Can a dirty fuel injector cause the P0265 code?
No, a dirty fuel injector would likely cause flow issues rather than high voltage in the control circuit. P0265 is more often related to electrical issues.
How can I prevent the P0265 code from recurring?
Regular maintenance, including inspecting wiring and connectors for damage and ensuring proper fuel injector operation, can help prevent this code from reappearing.
Will clearing the code with a scanner fix the P0265 issue?
Clearing the code will turn off the check engine light temporarily, but it won't fix the underlying problem. The code will likely return if the issue isn't addressed.
