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.
To effectively diagnose a gas smell in your 2017 Nissan 370Z, start by ensuring your safety; work in a well-ventilated area and avoid open flames. Begin with a visual inspection under the vehicle to identify any obvious fuel leaks, such as puddles or drips, which can indicate a problem in the fuel system. Next, check the fuel cap to ensure it is tightly secured, as a loose or damaged cap can lead to gas odors escaping. Proceed to examine the fuel lines and connections for any signs of wear or leaks, tightening any loose fittings and replacing damaged components as necessary. Don’t overlook the fuel injector O-rings, as worn or damaged O-rings can also contribute to fuel leaks. Additionally, inspect the fuel tank for any cracks or damage that could be the source of the smell. If you have access to an OBD-II scanner, use it to check for any error codes that may provide further insight into the issue. If these steps do not reveal the source of the gas smell, or if you suspect a more serious problem, it is advisable to consult a qualified mechanic for a comprehensive diagnosis. By following this methodical approach, you can effectively identify and address the cause of the gas smell in your vehicle.
If you're experiencing a gas smell in your 2017 Nissan 370Z, it's essential to understand the potential causes to address the issue effectively. A fuel leak is often the primary suspect, which could arise from damaged fuel lines, leaking fuel injectors, or a faulty fuel tank seal. Additionally, the evaporative emissions system, responsible for controlling fuel vapor release, may be malfunctioning, contributing to the odor. A loose or damaged fuel cap is another common yet easily overlooked issue that can allow fuel vapors to escape. Moreover, leaks in the exhaust system, such as those from a cracked exhaust manifold or a damaged catalytic converter, can create a gas-like smell inside the vehicle. Lastly, engine problems, including a rich fuel mixture or malfunctioning components, can lead to unburned fuel entering the exhaust system, resulting in a noticeable gas odor. It's crucial to address these concerns promptly for your safety and the vehicle's performance, and seeking a qualified mechanic for a thorough inspection can help identify and resolve the underlying problem effectively.
Addressing a gas smell in your 2017 Nissan 370Z is not just a minor inconvenience; it is a pressing safety concern that requires immediate attention.
