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.

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 diagnosing a gas smell in your 2019 Chevrolet Equinox, it's essential to adopt a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Start by visually inspecting the area beneath your vehicle for any signs of fuel leaks, such as puddles or drips, which can indicate a problem with the fuel system. Next, ensure that the fuel cap is securely tightened, as a loose or damaged cap can allow gas odors to escape. Following this, examine the fuel lines for any visible damage or leaks, as these can also contribute to the smell. Pay special attention to the fuel injector O-rings, as they can degrade over time and lead to gas odors if worn or damaged. Additionally, inspect the fuel tank for any cracks or signs of damage that could be causing the smell. If, after these checks, you are still unable to identify the source of the gas odor, it is advisable to consult a qualified mechanic for a thorough inspection. This methodical approach not only helps in pinpointing the issue effectively but also ensures that you address the simplest potential problems first, saving time and effort in the diagnostic process.
If you notice a gas smell in your 2019 Chevrolet Equinox, it’s crucial to identify the underlying cause to ensure safety and prevent further damage. One of the most common culprits is a fuel leak, which can occur in various parts of the fuel system, including the fuel tank, lines, or injectors. A visual inspection of these components can help you spot any obvious signs of leakage. Additionally, a faulty fuel injector may not atomize fuel correctly, leading to a strong gasoline odor; checking for any signs of wear or malfunction can be beneficial. Another area to investigate is the evaporative emissions system, where issues like a malfunctioning charcoal canister or purge valve can allow gas vapors to escape. Don’t overlook the gas cap, as a loose or damaged cap can also release fuel vapors into the cabin. Lastly, consider the exhaust system; leaks from components such as the exhaust manifold or catalytic converter can sometimes mimic a gas smell. While some of these checks can be performed at home, it’s advisable to consult a qualified mechanic for a thorough inspection to ensure your vehicle remains safe and operational.
Addressing a gas smell in your 2019 Chevrolet Equinox is not just a matter of inconvenience; it is a pressing safety concern that should never be overlooked. The presence of gasoline fumes can indicate a fuel leak, which poses a significant fire hazard due to the highly flammable nature of gasoline. Moreover, inhaling these fumes can lead to serious health issues, including headaches, dizziness, and nausea, making it essential to prioritize your well-being. Ignoring this warning sign can escalate into more severe problems, such as engine damage or decreased vehicle performance, which could result in costly repairs down the line. Therefore, if you detect a gas smell, it is crucial to act swiftly by either conducting a thorough inspection yourself or seeking professional help to identify and rectify the source of the odor. Taking immediate action not only ensures your safety but also protects the integrity of your vehicle.
