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 2017 Nissan Quest, it's crucial to adopt a systematic diagnostic approach to identify the source of the issue effectively. Start by checking the fuel cap, as a loose or damaged cap is a common and easily fixable cause of gas odors. Next, inspect the area around your vehicle for any visible fuel leaks, particularly under the fuel tank and along the fuel lines, as these are frequent culprits. If the smell continues, turn your attention to the evaporative emissions system, which can develop faults leading to fuel vapor leaks. Additionally, examine the exhaust system for any leaks that could allow fumes to infiltrate the cabin. If these initial checks do not uncover the source of the gas smell, it may be prudent to seek the expertise of a professional mechanic who can perform a comprehensive inspection. By following this methodical approach, you can efficiently diagnose and address the gas smell, ensuring your Nissan Quest remains safe and operational.
If your 2017 Nissan Quest is emitting a gas smell, it’s crucial to identify the underlying cause to ensure both safety and vehicle performance. One common issue could be a leaking fuel injector, which can lead to fuel seeping into the engine compartment and creating a strong odor. Additionally, inspect the fuel lines for any signs of damage or leaks, as these can also contribute to the gas smell. Another area to check is the gas cap; if it’s loose or damaged, it may not seal properly, allowing fuel vapors to escape. Furthermore, a leak in the fuel tank itself can produce a noticeable gas odor both inside and outside the vehicle. Lastly, consider the evaporative emissions system, particularly the charcoal canister, which can malfunction and allow gas fumes to enter the cabin. Addressing these issues promptly is essential, and while some repairs may be manageable for a DIYer, others may require professional assistance to ensure safety and compliance with regulations.
Addressing a gas smell in your 2017 Nissan Quest is not just a minor inconvenience; it is a critical safety concern that demands immediate attention. Ignoring this issue can lead to severe consequences, including the risk of fire or explosion due to gasoline leaks, especially if there are any ignition sources nearby. Furthermore, the health implications of inhaling gasoline fumes are significant, with symptoms ranging from dizziness and headaches to more serious long-term health effects. Additionally, a gas smell often indicates a leak in the fuel system, which can compromise your vehicle's fuel efficiency and potentially cause extensive engine damage if left unaddressed. Therefore, it is essential to act swiftly and investigate the source of the gas smell to ensure your safety and the longevity of your vehicle.
