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 diagnosing a gas smell in your 2011 Jeep Grand Cherokee, it's crucial to take a systematic approach to identify the source of the issue. Start with the simplest potential cause: the gas cap. A loose or damaged gas cap can easily allow fumes to escape, making it the first thing to check. If the cap is secure, move on to inspecting the fuel system for any visible leaks, particularly around the fuel lines and tank, as these areas are common sources of gas odors. Next, examine the emissions control system, focusing on the catalytic converter and related components, since malfunctions here can also lead to a gas smell. Conduct a smell test around the vehicle, especially near the gas cap and the rear passenger side, where leaks are more likely to occur. If these initial checks do not resolve the issue or if you are unsure about your findings, seeking the expertise of a professional mechanic is advisable for a thorough inspection and necessary repairs. By following this diagnostic approach, you can effectively pinpoint the cause of the gas smell and take appropriate action to resolve it.
If your 2011 Jeep Grand Cherokee emits a gasoline odor, it’s crucial to investigate the underlying causes to ensure safety and prevent further complications. One of the most common issues is a gasoline leak, which can occur in various areas, including the engine bay and undercarriage, and poses a serious fire risk. Additionally, the smell may stem from the evaporative emissions system, particularly if the evap canister is venting fumes, often noticeable near the gas cap. Another potential culprit could be damaged or worn fuel lines, which can leak fuel after short drives, leading to a strong gas smell. Lastly, if you notice the odor after parking your Jeep with a full tank, it may indicate a problem with a drain hose located near the rear driver side. Addressing these issues promptly is essential for maintaining vehicle safety and performance, so if you detect a gas smell, consider conducting a thorough inspection or consulting a professional mechanic.
Addressing a gas smell in your 2011 Jeep Grand Cherokee is not just a matter of convenience; it is a critical safety issue that demands immediate attention. The presence of gasoline fumes can indicate a leak, which poses a significant fire hazard that could lead to combustion or even an explosion. Additionally, inhaling these fumes can have serious health implications, including dizziness, headaches, and nausea, which can escalate with prolonged exposure. Beyond the immediate health and safety risks, neglecting this issue can result in further damage to your vehicle, leading to costly repairs down the line. Therefore, it is essential to investigate and resolve any gas smell as soon as possible to protect both your well-being and the integrity of your Jeep Grand Cherokee.
