The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
A failing catalytic converter can cause a vehicle to fail emissions tests and turn on the check engine light. The exhaust might have an unusual smell. A restricted catalytic converter can result in a loss of engine power.

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 dealing with a gas smell in your 2014 Dodge Journey, it's essential to adopt a systematic diagnostic approach. Start by checking the gas cap, as a loose or damaged cap is often the simplest and most common culprit. If the cap is secure, proceed to inspect the EVAP system for any leaks or damaged hoses, as this system is designed to prevent fuel vapors from escaping. Utilizing an OBD2 scan tool can help identify any error codes related to the EVAP system or fuel delivery issues. Next, visually examine the fuel lines and injectors for signs of leaks, as these components can deteriorate over time and lead to fuel odors. If no issues are found, inspect the fuel tank for cracks or holes, which can pose serious safety risks. Additionally, check the engine performance; if it’s running rich, it may indicate problems with fuel injectors or sensors that need addressing. Lastly, don’t forget to check the engine oil for gasoline contamination, as this can signal deeper internal issues. By following this structured approach, you can effectively diagnose and address the source of the gas smell in your vehicle. If you encounter complexities beyond your comfort level, consulting a professional mechanic is advisable to ensure safety and accuracy in diagnosis.
If your 2014 Dodge Journey is emitting a gas smell, it’s essential to understand the common problems that could be at play, particularly within the EVAP and fuel delivery systems. The EVAP system is crucial for capturing fuel vapors from the gas tank, and issues such as leaky hoses, a faulty purge valve, or an over-saturated charcoal canister can lead to noticeable gas odors. Inspecting the hoses and connections for any signs of wear or damage is a good starting point, as is ensuring that the gas cap is secure and in good condition. On the other hand, the fuel delivery system can also be a culprit; leaks from the fuel pump, fuel lines, or even a malfunctioning fuel injector can release vapors that contribute to the smell. For a thorough diagnosis, consider using an OBD2 scan tool to check for any error codes, and visually inspect all relevant components for leaks. Addressing these issues promptly is not only vital for your vehicle's performance but also for your safety, especially if you frequently transport passengers.
Addressing a gas smell in your 2014 Dodge Journey is not just a matter of inconvenience; it is a pressing safety concern that requires immediate attention. Ignoring this issue can lead to severe consequences, including the risk of fire or explosion due to potential fuel leaks from the tank or lines. Additionally, inhaling gasoline fumes poses significant health risks, such as dizziness and nausea, which can escalate with prolonged exposure. For those inclined to take a DIY approach, it is essential to first ensure your safety by avoiding any ignition sources around the vehicle. Begin by visually inspecting the fuel system for obvious leaks or damage, particularly around the fuel tank and lines. If you notice any signs of wear or if the smell persists, it is crucial to consult a professional mechanic for a thorough diagnosis and repair. Remember, while DIY fixes can be rewarding, the urgency of this situation means that sometimes, expert intervention is the safest route to take.
