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. Also, in some models, there may be a popping sound accompanying the check engine light, as the leak detection pump continuously attempts to pressurize the fuel tank. The canister may also cause difficulty starting the engine, a rough idle, and poor fuel mileage.
When the fuel filter begins to clog, the engine suffers from fuel starvation. This will cause a significant reduction in power and may also cause a misfire. These conditions may be intermittent, or constant and worsen over time. As the issue progresses, the engine may being to stall immediately after starting, fail to start, hesitate under throttle, or stall at particular angles on hills.

A fuel tank leak may also cause difficulty starting the engine, a rough idle, and poor fuel mileage. When a fuel tank is simply corroded to the point of failure, the exterior tank condition rarely shows damage. 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.
When faced with a gas smell in your 2013 Mazda 6, it's essential to adopt a systematic diagnostic approach to identify the root cause. Start by inspecting the fuel system for any visible leaks, focusing on components like fuel lines, injectors, and the fuel tank. A faulty fuel cap is another common culprit, so ensure it is securely tightened and in good condition to prevent gas vapors from escaping. Utilizing an OBD-II scanner can help you check for any error codes that may indicate issues with the fuel system or emissions components. Next, examine the evaporative emissions system, including the charcoal canister and purge valve, for any signs of malfunction. Additionally, inspect the exhaust system for leaks or damage that could contribute to the gas odor. Finally, monitor your engine's performance for any misfires or unusual behavior, as these can also lead to unburned fuel entering the exhaust system. By following these steps, you can effectively diagnose and address the gas smell in your vehicle, ensuring a safer and more efficient driving experience.
If you're experiencing a gas smell in your 2013 Mazda 6, it's crucial to identify the underlying cause to ensure your safety and the vehicle's performance. One of the most common culprits is a fuel leak, which can occur from various components such as fuel injectors, fuel lines, or even the fuel tank itself. Inspecting these areas for any signs of leakage can help you pinpoint the issue. Additionally, a faulty or loose fuel cap can lead to fuel vapors escaping, so checking the cap for damage or ensuring it is securely fastened is a simple yet effective step. Another potential source of the odor could be related to the evaporative emissions system, which is designed to contain fuel vapors; any malfunction here may require further investigation. Furthermore, an exhaust system leak, particularly near the engine compartment, can sometimes mimic a gas smell, so examining the exhaust components for any cracks or holes is advisable. Lastly, if you've recently overfilled your gas tank, this could lead to fuel spillage and a noticeable odor inside the cabin. Addressing these issues promptly not only enhances your vehicle's safety but also prevents more significant problems down the line. If you're unsure about any of these checks, consulting a qualified mechanic can provide peace of mind and ensure the problem is resolved effectively.
Addressing a gas smell in your 2013 Mazda 6 is not just a matter of convenience; it is an urgent safety concern that should be prioritized. Gas leaks pose a significant risk of fire or explosion, particularly if the fumes come into contact with hot engine parts or electrical sparks. Moreover, inhaling gasoline vapors can lead to serious health issues, including dizziness, headaches, and nausea, which can escalate with prolonged exposure. Ignoring this warning sign can also result in further damage to your vehicle, leading to expensive repairs that could have been avoided with timely intervention. Therefore, if you notice a gas smell, it is imperative to seek professional assistance immediately to diagnose and resolve the issue, ensuring both your safety and the longevity of your vehicle.
