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.
When the fuel filter begins to clog, the engine suffers from fuel starvation. This will cause a significant reduction in power and may also cause a misfire. These conditions may be intermittent, or constant and worsen over time. As the issue progresses, the engine may being to stall immediately after starting, fail to start, hesitate under throttle, or stall at particular angles on hills.

When diagnosing a gas smell in your 2009 Lexus ES350, it's essential to adopt a systematic approach that prioritizes simpler checks before delving into more complex issues. Start by inspecting the area beneath your vehicle for any visible fuel leaks, as this is often the most straightforward cause. Next, examine the fuel injectors for signs of leakage, as a malfunctioning injector can contribute significantly to the odor. Don’t overlook the evaporative emissions system; check components like the charcoal canister and purge valve for defects, as these can also lead to gas smells if they are not functioning correctly. Additionally, ensure that your gas cap is secure and undamaged, as a loose or faulty cap can allow fuel vapors to escape. Finally, inspect the exhaust system for any leaks or damage, as these can produce a gas-like odor as well. By following this diagnostic approach, you can effectively narrow down the potential causes of the gas smell and address the issue more efficiently. If you find yourself unable to pinpoint the problem, seeking assistance from a qualified mechanic is always a wise choice to ensure your vehicle's safety and performance.
When you detect a gas smell in your 2009 Lexus ES350, it's crucial to investigate several common problems that could be the source. One of the primary culprits is fuel leaks, which can occur due to damaged fuel lines or faulty fuel injectors. Inspecting these components for any signs of wear or damage can help identify leaks. Additionally, issues with the evaporative emissions system may contribute to the gas odor, as this system is designed to manage fuel vapors. A malfunctioning system can lead to vapor escape, so checking for any broken or disconnected hoses is advisable. Another simple yet often overlooked cause is a faulty fuel cap; ensure that it is tightly secured and free from cracks. Furthermore, a clogged fuel filter can disrupt fuel flow and combustion, potentially resulting in a gas smell, so consider replacing it if it hasn't been changed recently. Lastly, don't rule out exhaust system problems, such as leaks or issues with the catalytic converter, which can also emit fuel odors. By systematically examining these areas, you can effectively diagnose and address the source of the gas smell, ensuring your vehicle remains safe and functional.
Addressing a gas smell in your 2009 Lexus ES350 is not just a matter of inconvenience; it is a critical safety concern that requires immediate attention. Gas leaks pose a significant risk of fire or explosion, particularly in the confined space of a vehicle, where flammable vapors can accumulate quickly. Moreover, inhaling gas fumes can lead to serious health issues, including dizziness, headaches, and nausea, which can impair your ability to drive safely. Ignoring this warning sign can also result in further damage to your vehicle's components, leading to more extensive and expensive repairs down the line. Therefore, if you detect a gas smell, it is essential to act swiftly by consulting a professional mechanic who can diagnose and resolve the issue, ensuring both your safety and the longevity of your vehicle.
