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 2017 INFINITI QX70, it's essential to adopt a systematic diagnostic approach to identify the root cause effectively. Start by checking for fuel leaks, as these can often be the most straightforward issue to resolve. Inspect the fuel lines, tank, and injectors for any visible signs of leakage. Next, ensure that the fuel cap is tightly sealed; a loose or damaged cap can easily allow gas vapors to escape, contributing to the odor. If these initial checks do not reveal the problem, turn your attention to the fuel filter, as a clogged filter can lead to fuel accumulation and a noticeable gas smell. Additionally, examine the EVAP system, which is crucial for containing fuel vapors; any malfunction here could be a significant contributor to the issue. Lastly, consider the exhaust system, as leaks or damage can also produce a gas-like odor. If these steps do not lead to a solution, consulting a qualified mechanic is advisable to conduct a more thorough diagnosis. By following this structured approach, you can efficiently pinpoint the cause of the gas smell and take appropriate action.
If you're experiencing a gas smell in your 2017 INFINITI QX70, it's essential to identify the underlying issues to ensure your safety and the vehicle's performance. A fuel leak is often the primary culprit, which could arise from damaged fuel lines, leaking fuel injectors, or a faulty fuel tank cap. Additionally, problems with the evaporative emissions system can allow fuel vapors to escape, contributing to the odor. Another potential source is a leak in the exhaust system, which may permit gas-like fumes to enter the cabin, often due to a cracked exhaust manifold or a damaged catalytic converter. Overfilling the gas tank is a common yet easily overlooked cause, as it can lead to gasoline spilling and creating a strong smell. Lastly, faulty engine components, such as fuel injectors or spark plugs, can also produce a gas odor. To address these issues effectively, it's advisable to conduct a thorough inspection of these areas or consult a qualified mechanic for a comprehensive diagnosis. Taking prompt action can help prevent further complications and ensure a safe driving experience.
