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 faced with a gas smell in your 2011 Nissan Cube, it's essential to adopt a systematic diagnostic approach to identify the root cause effectively. Start with a thorough visual inspection of the vehicle, focusing on the fuel system components such as the fuel lines, injectors, and tank for any signs of leaks. If you notice any wet spots or strong odors near these areas, it could indicate a fuel leak. Next, check the condition of the fuel injectors; a malfunctioning injector may not atomize fuel properly, leading to a noticeable gas smell and symptoms like rough idling or decreased fuel efficiency. Additionally, inspect the evaporative emissions system, which includes components like the charcoal canister and purge valve, as issues here can also contribute to fuel odors. Don’t overlook the exhaust system; a leak near the engine can sometimes mimic a gas smell. Lastly, ensure that you are not overfilling the gas tank during refueling, as this can lead to fuel spillage and odors. If the check engine light is on, using an OBD-II scanner can provide valuable error codes that guide your diagnosis. If these steps do not reveal the source of the smell, consulting a professional mechanic may be necessary for a more in-depth evaluation. By following this structured approach, you can effectively narrow down the potential causes and address the gas smell issue in your vehicle.
If your 2011 Nissan Cube is emitting a gas smell, it’s crucial to identify the underlying issues to ensure both safety and vehicle performance. Common problems that could lead to this unpleasant odor include a leaking fuel injector, which allows gas fumes to infiltrate the cabin, or faulty fuel lines that may be cracked or damaged, causing fuel to leak onto the engine or ground. Additionally, a loose or damaged gas cap can permit fuel vapors to escape from the tank, contributing to the smell. More serious concerns, such as a leak in the fuel tank itself, should be addressed immediately due to potential safety hazards. Lastly, issues with the evaporative emissions system, including a malfunctioning charcoal canister or purge valve, can also result in gas odors. If you notice a gas smell in your vehicle, it’s advisable to consult a qualified mechanic for a thorough diagnosis and prompt repairs to maintain your vehicle's safety and functionality.
Addressing a gas smell in your 2011 Nissan Cube is not just a matter of convenience; it is a critical safety concern that requires immediate attention. Gas leaks can create a significant fire hazard, endangering both the vehicle and its occupants. Moreover, inhaling gas fumes poses serious health risks, leading to symptoms such as dizziness, nausea, and headaches, which can impair your ability to drive safely. Ignoring the smell of gas can also result in further damage to your vehicle's components, potentially leading to expensive repairs down the line. Therefore, if you detect a gas smell, it is essential to act quickly—either by inspecting the vehicle yourself or seeking professional help—to ensure the safety of everyone in and around the car.
