The most common reasons a 2013 Chevrolet Camaro smells like gas are the gas cap, the fuel system, or the emissions control system.
  • Gas Cap: A loose or damaged gas cap can cause fuel vapors to escape, triggering the check engine light and potentially affecting fuel system pressure.
  • Emissions Control System: A faulty emissions control system can lead to increased hydrocarbon emissions and trigger the check engine light due to malfunctioning components like the EGR valve or O2 sensors.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

The check engine light will illuminate any time there is a failed EVAP system test. This will be indicated by the various on-board diagnostics trouble codes that are stored in the vehicle's memory.

The canister may also cause difficulty starting the engine, a rough idle, and poor fuel mileage.

The inside of the fuel tank will be rusted or corroded, and rust flakes or other debris may be floating in the fuel.

For most vehicles, the only symptom will be a check engine light or fuel tank filler cap light illuminating on the driver instrument cluster. This is to signal that there is an evaporative emissions (EVAP) leak. In some situations, the vehicle may take longer than normal to start, or, more rarely, the engine may not start at all. on-board diagnostic (OBD) trouble codes will refer to EVAP system failures such as a small or massive EVAP system leak. Lastly, the powertrain control module may notice a lean running condition, which could even lead to random and infrequent misfires.

What are the potential causes and diagnostic steps for a gas smell in a 2013 Chevrolet Camaro?

When dealing with a gas smell in your 2013 Chevrolet Camaro, it's essential to adopt a systematic diagnostic approach to identify and resolve the issue effectively. Start by inspecting the fuel system, as this is often the primary source of gas odors. Look for any visible leaks in the fuel lines or the fuel tank itself, as these can lead to significant gas smells both inside and outside the vehicle. Next, check the condition of the spark plugs; if they show signs of oil contamination, this could indicate a deeper problem that may be contributing to the gas smell. Additionally, consider environmental factors such as extreme heat, which can exacerbate the odor by causing fuel to expand. Conducting a thorough inspection of these components will help you pinpoint the cause of the gas smell, allowing you to take appropriate action to rectify the situation and ensure your vehicle remains safe and functional.

When you detect a gas smell in your 2013 Chevrolet Camaro, it's crucial to investigate the issue promptly, as it can indicate serious problems. One of the most common culprits is a fuel leak, which may stem from a damaged fuel line, a faulty fuel injector, or even a cracked fuel tank.
