This summary uses the existing diagnostic information shown in full below.
This code means that there's a problem with the fuel injector for cylinder number 2 in your car's engine. It's not getting enough power to work properly.
The engine control module (ECM) has detected a low voltage or resistance issue in the fuel injector circuit of cylinder 2.
P0264 is triggered when the ECM detects that the voltage or resistance in the fuel injector circuit for cylinder 2 is below the expected range. This can be due to wiring issues, a faulty injector, or problems with the ECM itself.
• Engine misfire
• Poor fuel economy
• Check Engine Light illuminated
• Faulty fuel injector
• Open or shorted injector circuit wiring
• Poor electrical connection at the injector or ECM
ECM: Engine Control Module
Injector: A device that sprays fuel into the engine's cylinders
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections for cylinder 2 injector.
• Test the injector for proper resistance and operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty fuel injector.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance checks
• Use quality fuel
• Inspect and clean injectors periodically
Engine Performance
• Have your vehicle inspected by a professional if you experience engine misfires.
• Regularly check for any warning lights on the dashboard.
Check with your vehicle manufacturer for specific warranty coverage on fuel injectors.
Injector circuit codes have been common with the introduction of electronic fuel injection systems.
Moderate – Should be addressed soon to avoid further engine performance issues.
Driving with a faulty injector can lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Under load conditions
The fuel injector for cylinder 2 is located on the engine, typically near the intake manifold.
Q: Can I drive with a P0264 code?
A: It's not recommended to drive for long periods with this code as it can lead to further engine issues.
Q: How do I clear a P0264 code?
A: After repairs, use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
