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 2016 INFINITI QX70, it's essential to adopt a systematic diagnostic approach to identify the root cause effectively. Start by inspecting the fuel system for any visible leaks, focusing on components like fuel lines, injectors, and the fuel tank. A common culprit can be a faulty fuel cap, so ensure it is securely tightened and in good condition to prevent gas vapors from escaping. Next, examine the exhaust system for any signs of leaks or damage, as these can also contribute to a gas odor. Utilizing a diagnostic scanner to check for error codes related to the fuel system or emissions components can provide valuable insights into underlying issues. If these initial checks do not reveal the source of the smell, it may be prudent to seek a professional inspection to accurately diagnose and resolve the problem. By following this structured approach, you can efficiently troubleshoot the gas smell and ensure your vehicle remains safe and functional.
When you notice a gas smell in your 2016 INFINITI QX70, it's essential to act quickly to identify and resolve the issue for your safety and the vehicle's integrity. Common culprits include fuel leaks, which can originate from the fuel tank, fuel lines, or fuel injectors, leading to a hazardous situation if left unchecked. A malfunctioning fuel injector may also contribute to the problem by leaking fuel into the engine compartment. Additionally, issues with the evaporative emissions system, such as a faulty charcoal canister or purge valve, can result in noticeable gas odors. It's also important to check the gas cap; a loose or damaged cap can allow fuel vapors to escape, creating a gas smell inside the vehicle. Lastly, don't ignore potential leaks in the exhaust system, which can arise from a cracked exhaust manifold or a damaged catalytic converter. To ensure your vehicle remains safe and functional, it's advisable to consult a qualified mechanic who can perform a comprehensive inspection and address any underlying issues effectively.
