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.

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 you detect a gas smell in your 2011 Acura TSX, it's crucial to approach the diagnosis methodically to ensure safety and effectiveness. Start by inspecting the vehicle for any visible gasoline leaks, particularly under the car and around the engine compartment, as these are often the most straightforward issues to identify. If no leaks are apparent, the next step is to assess the functionality of the fuel injectors, as faulty injectors can lead to fuel odors in the cabin. If the injectors are functioning properly, turn your attention to the evaporative emissions system, which can also contribute to gas smells if it has malfunctions. Finally, examine the exhaust system for any leaks or damage, as these can sometimes allow exhaust gases to enter the vehicle, mimicking a gas smell. By following this structured diagnostic approach, you can effectively narrow down the source of the gas odor and take the necessary steps to resolve the issue.
If your 2011 Acura TSX is emitting a gas smell, it’s crucial to identify the underlying issues to ensure safety and vehicle performance. One of the most common culprits is a fuel leak, which can occur from various points in the fuel system, including fuel injectors, lines, or even the fuel tank itself. Additionally, a faulty fuel cap can lead to vapor escape, so checking its condition and ensuring it’s properly secured is a simple first step. Another area to investigate is the evaporative emissions control system, which is responsible for capturing fuel vapors; any malfunction here can result in noticeable odors. Furthermore, a clogged fuel filter may hinder fuel flow and contribute to the smell, while exhaust system issues, such as leaks or problems with the catalytic converter, can also produce a gas-like scent. For those inclined to DIY, inspecting these components can help pinpoint the issue, but if the problem persists, consulting a qualified mechanic is advisable to prevent potential hazards.
Addressing a gas smell in your 2011 Acura TSX is not just a minor inconvenience; it is a critical safety concern that demands immediate attention. The presence of gasoline fumes can indicate a leak, which poses a significant fire hazard that could endanger both you and others on the road. Additionally, inhaling these fumes can lead to serious health issues, including dizziness, headaches, and nausea, making it essential to prioritize your well-being. Furthermore, neglecting this issue can result in more severe mechanical problems down the line, potentially leading to costly repairs that could have been avoided with timely intervention. Therefore, if you detect a gas smell, it is crucial to seek professional assistance without delay to diagnose and resolve the issue, ensuring your vehicle remains safe and reliable.
