This summary uses the existing diagnostic information shown in full below.
The car's computer noticed that the engine isn't running smoothly because it's running low on a special type of fuel.
This code indicates that the engine control module (ECM) has detected a misfire condition when the vehicle is running on alternative fuel and the fuel level is low.
The P2E61 code is triggered when the ECM detects a misfire in one or more cylinders while the vehicle is operating on an alternative fuel source, such as CNG or LPG, and the fuel level is low. This could be due to insufficient fuel supply or improper combustion.
• Engine runs rough
• Decreased fuel efficiency
• Check engine light on
• Low alternative fuel level
• Faulty fuel injectors
• Ignition system issues
ECM: Engine Control Module
CNG: Compressed Natural Gas
LPG: Liquefied Petroleum Gas
• Check the alternative fuel level
• Inspect fuel injectors for clogs or damage
• Examine ignition components like spark plugs and coils
• Refill alternative fuel tank
• Clean or replace faulty fuel injectors
• Repair or replace ignition components
• OBD-II scanner
• Fuel pressure gauge
• Multimeter

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regularly check fuel levels
• Maintain fuel system components
• Use high-quality alternative fuel
Engine Performance
• Keep your alternative fuel tank filled above a quarter
• Have regular maintenance checks
• Use recommended fuel types
Repairs may be covered under the vehicle's emissions warranty if applicable.
This code has become more common with the increase in vehicles using alternative fuels.
Moderate – Addressing this issue soon can prevent further engine damage.
Driving with a misfire can cause increased emissions and potential engine damage.
• Engine running on alternative fuel
• Low fuel condition
The fuel system components are typically located near the engine and fuel tank.
Q: Can I drive with a P2E61 code?
A: It's not recommended as it can lead to engine damage and increased emissions.
Q: What is alternative fuel?
A: Alternative fuel refers to non-traditional fuels like CNG or LPG used to power vehicles.
