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.

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 diagnosing a gas smell in your 2007 Mitsubishi Lancer, it's essential to adopt a systematic approach that prioritizes safety and efficiency. Start by checking for visible leaks under the vehicle, as this can quickly indicate a problem with the fuel system. Next, inspect the fuel lines and connections for any signs of wear, such as cracks or loose fittings, which could be the source of the odor. Don't overlook the fuel tank; any damage or leaks here can also lead to gas fumes escaping. Additionally, examine the fuel injector and fuel filter, as issues in these components can contribute to the smell. It's also crucial to assess the evaporative emissions system and the exhaust system for leaks, as these can allow gas fumes to enter the cabin. Finally, inspect the charcoal canister for any signs of damage. If these steps do not reveal the source of the gas smell, it may be time to consult a professional mechanic for a more thorough inspection. By following this diagnostic approach, you can effectively identify and address the issue, ensuring your vehicle remains safe and functional.
If your 2007 Mitsubishi Lancer is emitting a gas smell, it’s crucial to identify the underlying issues to ensure both safety and vehicle performance. One common culprit is a leaking fuel injector, which can lead to unburned fuel escaping into the engine compartment, creating a strong odor. Additionally, inspect the fuel lines for any cracks or damage, as these can also result in fuel leaks that contribute to the smell. Don’t overlook the gas cap; a loose or damaged cap can allow fuel vapors to escape, leading to noticeable odors inside the car. Furthermore, check for leaks in the fuel tank itself, as this can be a significant source of gasoline smells. Lastly, consider the evaporative emissions system, which includes components like the charcoal canister and purge valve; if these parts are malfunctioning, they can also produce gas odors. Addressing these issues promptly not only enhances your vehicle's performance but also ensures your safety on the road.
Addressing a gas smell in your 2007 Mitsubishi Lancer is not just a minor inconvenience; it is a critical safety concern that demands immediate action. Gas leaks can lead to catastrophic outcomes, including the risk of fire, which endangers not only your life but also the lives of those around you. Moreover, the inhalation of gas fumes poses serious health risks, with symptoms ranging from dizziness and headaches to more severe conditions with prolonged exposure. Ignoring this warning sign can also result in significant damage to your vehicle's fuel system, leading to costly repairs that could have been avoided with timely intervention. Therefore, if you detect a gas smell, it is imperative to investigate the source and address it without delay to safeguard your health and your vehicle's integrity.
