This means that the 5th cylinder in your car's engine isn't working properly when using a different kind of fuel, like natural gas or ethanol, instead of regular gasoline.
The engine control module (ECM) has detected a misfire in cylinder 5 when the engine is running on an alternative fuel.
This code is set when the ECM detects that cylinder 5 is not firing correctly when the engine is operating on an alternative fuel source. Misfires can occur due to a variety of reasons such as fuel delivery issues, ignition problems, or mechanical failures within the cylinder.
• Rough engine idle
• Reduced fuel efficiency
• Check engine light illuminated
• Faulty spark plug in cylinder 5
• Fuel injector issue for cylinder 5
• Ignition coil failure for cylinder 5
ECM: Engine Control Module
Misfire: A failure of the air/fuel mixture in a cylinder to ignite at the proper time.
• Check for any other related trouble codes.
• Inspect the spark plug and ignition coil for cylinder 5.
• Test the fuel injector for cylinder 5.
• Replace the spark plug for cylinder 5.
• Replace or repair the ignition coil for cylinder 5.
• Clean or replace the fuel injector for cylinder 5.
• OBD-II scanner
• Spark plug socket
• Multimeter

Moderate
• Chevrolet Impala
• Ford F-150
• Toyota Camry
• Regularly maintain ignition system components.
• Use the correct type of alternative fuel.
• Perform regular engine tune-ups.
Engine Performance
• Avoid using alternative fuels if the problem persists.
• Consult a professional mechanic for a thorough diagnosis.
Check with your vehicle manufacturer for warranty coverage on engine components.
This code is more common in vehicles equipped with dual-fuel systems that allow switching between gasoline and an alternative fuel.
Moderate – Addressing this issue promptly can prevent further engine damage.
Driving with a misfire can cause increased emissions and may not be compliant with local environmental regulations.
• Engine running on alternative fuel
• Vehicle at operating temperature
Cylinder 5 is typically located on the engine block, and the exact location can vary depending on the engine configuration.
Q: Can I continue driving with this code?
A: It's best to address the issue soon to avoid potential engine damage.
Q: Will using regular gasoline fix the problem?
A: Switching fuels might temporarily alleviate symptoms, but the underlying issue should still be diagnosed and repaired.
