The most common reasons a 2013 Ford Fusion has a check engine light are an emissions system component, a sensor, or a catalytic converter.
  • Emissions System: A faulty emissions system component, such as an oxygen sensor or EGR valve, can lead to increased emissions and trigger the check engine light.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2013 Ford Fusion has a check engine light?

Common Repairs

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 faulty oxygen sensor is one of the most common causes of a check engine light. Symptoms may include a decrease in fuel mileage, hesitation or misfiring from the engine, rough idling or even stalling. A faulty sensor may cause the vehicle to fail an emissions test.

Any time there is an emissions fault the check engine light will be displayed. The purpose of the check engine light is to inform the driver that an emission related fault has been found, and that there are on-board diagnostic (OBD) trouble codes stored in the powertrain or engine control module. Additionally, since the emissions systems are so intertwined into engine control and transmission control systems, symptoms may include nearly any sort of drivability concerns. This may include harsh shifting, failure to shift, hesitation on acceleration, jerking, engine failure to start or run, loss of power, or any number of other drivability issues.

Due to the nature of electrical systems on modern vehicles, the range of problems these can cause are nearly limitless. However, there is a way to categorize them in two ways. Permanent and intermittent problems. Permanent problems appear and remain. This may be the vehicle will not start, the radio does not work, or the door chime will not turn off among many, many others. These problems are more straight-forward to diagnose since they present themselves at all time. This means there will always be a fault to find. Intermittent electrical problems, however, can be difficult or impossible to locate, since they appear then disappear without warning. The best case scenario for an intermittent issue is when replicating the problem is easily accomplished and understood. This allows a technician to make an issue semi-permanent, allowing them to find the fault. Other issues that come and go without warning and cannot be replicated on demand must occur when the technician is servicing the vehicle, otherwise there is no problem to correct. It is most important to understand that electrical system faults always require inspection, and can include the vehicle working in any manner, or not working at all.

Like we noted in the last section, general diagnosis symptoms are the most vague of the bunch. There are several diagnostic spectrums, electrical diagnosis, drivability diagnostics, engine diagnostics, transmission diagnostics, and the list could continue for about 5 or 10 more spectrums of diagnostics. The most important take-away here, is that general diagnostics are diagnostics that have no other spectrum in which they fit, or the problem is unknown. This means that any vehicle left outside of a repair facility with the keys and an authorization to perform diagnosis will be diagnosed under the general diagnosis spectrum.

When the Check Engine Light comes on, you may experience engine performance issues such as poor acceleration, rough idling, or an engine that won't start. In some cases, no abnormal symptoms will be experienced. Other systems like the transmission or ABS can cause the Check Engine Light to illuminate and lights for those systems can come on at the same time. Similar lights may say "Check Engine Soon", "Malfunction Indicator Light" or just "Check". In rare case the engine can overheat.

What are the initial diagnostic steps to take for a check engine light on a 2013 Ford Fusion?

When faced with a check engine light on your 2013 Ford Fusion, it's essential to adopt a methodical diagnostic approach. Start by checking the gas cap; a loose or damaged cap is a common culprit that can easily trigger the light. Next, take a moment to observe the dashboard gauges for any unusual readings, as these can provide clues about underlying issues. Utilizing an OBD-II scanner is a crucial step; by connecting it to your vehicle's diagnostic port, you can retrieve specific error codes that pinpoint the problem. Additionally, inspect the condition of the spark plugs, as worn or faulty plugs can also cause the light to illuminate. Don't forget to check the fluid levels of essential fluids like oil and coolant, as low levels can lead to engine complications. Finally, examine the wiring and connections under the hood for any visible damage or corrosion, as faulty connections can trigger the check engine light. By following these steps, you can effectively gather information to diagnose the issue and potentially resolve it yourself.

What are the common problems that could cause the check engine light to illuminate in a 2013 Ford Fusion?

When the check engine light comes on in a 2013 Ford Fusion, it can signal a range of common issues that are often manageable for DIY enthusiasts. One of the simplest problems to check is a loose or damaged gas cap, which can easily be tightened or replaced. Another frequent culprit is a faulty oxygen sensor, which monitors the exhaust and can be replaced with basic tools. Additionally, issues with the catalytic converter, such as blockages or failures, may require more in-depth knowledge but can sometimes be diagnosed at home. The mass airflow sensor, responsible for measuring the air entering the engine, can also malfunction, leading to the check engine light illuminating. Spark plug wear or ignition coil defects are other common issues that can be addressed with some mechanical skill. Lastly, engine misfires and EGR valve problems can also trigger the light, indicating a need for further investigation. While some of these issues can be resolved with DIY methods, it’s crucial to have the vehicle properly diagnosed to ensure that the correct repairs are made, preventing further damage and maintaining optimal vehicle performance.

How urgent is it to address the check engine light in a 2013 Ford Fusion?

Addressing the check engine light in a 2013 Ford Fusion is not just a matter of convenience; it is a critical step in maintaining the vehicle's performance and safety. Ignoring this warning can lead to a cascade of issues, including reduced fuel efficiency and potential engine damage, which can escalate repair costs significantly. For DIY enthusiasts, understanding the urgency of this indicator is essential. While some issues may seem minor, they can quickly evolve into serious malfunctions that compromise the vehicle's reliability and safety. By diagnosing the problem early, you can not only save money on repairs but also ensure that your vehicle remains in optimal condition. Therefore, if the check engine light illuminates, it is advisable to investigate the cause promptly, whether through a diagnostic tool or by consulting a professional, to prevent further complications and maintain the longevity of your Ford Fusion.
