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 dealing with a gas smell in your 2010 Nissan Murano, it's crucial to follow a methodical diagnostic approach to accurately identify the source of the issue. Begin by inspecting the fuel system for any visible leaks, as this is a common cause of gas odors. Look closely at the fuel lines, injectors, and fuel tank for any signs of damage or leakage. Next, check the fuel cap to ensure it is securely tightened and in good condition, since a faulty cap can allow gas vapors to escape into the atmosphere. If these initial checks do not reveal the problem, utilize a diagnostic scanner to search for error codes that may point to issues within the fuel system or the evaporative emissions system. Pay special attention to components such as the charcoal canister and purge valve, as malfunctions in these areas can also lead to gas smells. Additionally, inspect the exhaust system for any leaks or damage, as these can sometimes produce a gas-like odor. Lastly, monitor your engine's performance for any signs of misfires or unusual sounds, which could indicate that unburned fuel is entering the exhaust system. By adhering to this structured approach, you can effectively diagnose and resolve the source of the gas smell in your vehicle.
When you detect a gas smell in your 2010 Nissan Murano, it’s crucial to identify the underlying cause to ensure both safety and vehicle performance. One of the most common culprits is a fuel leak, which can occur from damaged fuel lines or faulty fuel injectors, leading to a noticeable odor both inside and outside the vehicle. Additionally, issues with the evaporative emissions control system can cause fuel vapors to escape, contributing to the gas smell. A simple yet often overlooked problem could be a faulty fuel cap; if it’s loose or damaged, it can allow vapors to escape. Furthermore, a clogged or malfunctioning fuel filter may hinder the fuel system's efficiency, resulting in a gas odor. Lastly, don’t rule out exhaust system problems, such as leaks or a damaged catalytic converter, which can also lead to a gas smell inside the cabin. Addressing these issues promptly is essential, and while some may be manageable for a DIY enthusiast, others may require professional inspection to ensure safety and compliance with emissions standards.
Addressing a gas smell in your 2010 Nissan Murano is not just a minor inconvenience; it is a pressing safety concern that requires immediate attention. The presence of gasoline fumes can indicate a fuel leak, which poses a significant fire hazard and increases the risk of explosion, especially in a confined space like a vehicle. Moreover, inhaling gasoline vapors can lead to serious health issues, including dizziness, headaches, and nausea, which can impair your ability to drive safely. Ignoring this warning sign can also result in further damage to your car's fuel system, leading to more extensive and costly repairs down the line. Therefore, if you detect a gas smell, it is crucial to act swiftly—either by conducting a thorough inspection yourself or seeking professional assistance—to ensure both your safety and the longevity of your vehicle.
