This method is often considered a last resort or a stopgap measure before more comprehensive repairs are undertaken.

When a vehicle's CEL illuminates, it typically indicates a problem with the engine's computer system, which can be caused by various factors, including issues with the fuel system. Fuel line cleaner, designed to remove deposits and improve fuel flow, might offer a temporary solution by ensuring that the fuel is being delivered efficiently to the engine. This can sometimes lead to a reduction in engine misfires or other symptoms that trigger the CEL.

However, it's crucial to recognize that the effectiveness of fuel line cleaner is highly dependent on the specific issue causing the CEL. For instance, if the problem is a faulty fuel pump or a clogged fuel filter, using cleaner might not resolve the underlying issue. In such cases, the CEL will likely return once the cleaner's effects wear off, as the root cause remains unaddressed.

For temporary relief, fuel line cleaner can be an option, especially for minor issues or as a diagnostic tool. It can help identify if the CEL is triggered by fuel-related problems, allowing for further investigation. Nonetheless, it is essential to consult a professional mechanic to determine the exact cause and implement the necessary repairs.

In summary, while fuel line cleaner can provide a temporary fix for certain fuel-related issues that cause the Check Engine Light, it should not be relied upon as a long-term solution. Regular maintenance and timely repairs are crucial to ensuring the vehicle's optimal performance and longevity.
