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.

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. 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 2012 Mitsubishi Lancer, it's essential to adopt a methodical approach that prioritizes safety and efficiency. Start by checking for visible leaks under the vehicle, as this can quickly indicate if there's a significant issue with the fuel system. Next, inspect the fuel lines and connections for any signs of wear or looseness, which are common culprits for gas odors. Don’t overlook the fuel tank; any damage or leaks here can lead to fumes escaping. Additionally, examine the fuel injector and fuel filter, as both can contribute to the smell if they are malfunctioning or clogged. It's also crucial to assess the evaporative emissions control (EVAP) system, as leaks or malfunctions in this area can cause gas vapors to escape. Finally, check the exhaust system for leaks that might allow gas fumes to enter the cabin. By following this structured diagnostic approach, you can effectively identify the source of the gas smell and take the necessary steps to resolve the issue, ensuring your vehicle remains safe and functional.
If your 2012 Mitsubishi Lancer is emitting a gas smell, it’s crucial to identify the underlying cause to ensure both safety and vehicle performance. One of the most frequent culprits is a fuel leak, which can occur in various components such as the fuel tank, fuel lines, or injectors. Inspecting these areas for signs of wetness or damage can help pinpoint the issue. Additionally, a faulty fuel injector may leak fuel into the engine compartment, leading to a noticeable odor; checking for any irregularities in injector function is advisable. Another simple yet often overlooked cause is a gas cap that is loose, damaged, or missing, which can allow fuel vapors to escape. Ensuring that the gas cap is secure and in good condition can sometimes resolve the problem. Furthermore, issues with the evaporative emissions system, including the charcoal canister or purge valve, can also lead to gas smells, so examining these components may be necessary. Lastly, don’t rule out exhaust system leaks, as they can produce gas-like odors; inspecting the exhaust manifold and catalytic converter for cracks or damage is a good practice. Addressing these potential issues promptly can help maintain your vehicle's safety and efficiency.
When you detect a gas smell in your 2012 Mitsubishi Lancer, it is essential to act swiftly due to the serious safety risks involved. Gas leaks not only pose a significant fire hazard but can also lead to harmful health effects from inhaling toxic fumes. If you notice this odor, it is crucial to inspect your vehicle immediately. Start by checking for visible leaks around the fuel lines, connections, and the fuel tank. If you are comfortable doing so, you can also examine the fuel injectors and the engine bay for any signs of wear or damage. However, if the source of the smell is not easily identifiable or if you feel uncertain about performing these checks, it is advisable to seek professional assistance. Ignoring the issue can lead to more severe damage to your vehicle and potentially costly repairs, making it imperative to prioritize this concern for both your safety and the longevity of your car.
