Common Reasons For Check Engine Light

If you own a 2018 Ford Escape and notice that the check engine light has come on, it can be quite concerning. However, it’s important not to panic, as there are many common and easily fixable reasons for the check engine light to illuminate. In this section, we will explore some of the most common reasons for the check engine light in a 2018 Ford Escape, including oxygen sensor failure, faulty emissions control part, and malfunction with the fuel injection system.

Oxygen Sensor Failure

Oxygen sensors play a crucial role in monitoring the amount of oxygen in the exhaust system of your Ford Escape. When these sensors fail, it can lead to issues such as reduced fuel efficiency, increased emissions, and poor engine performance. A faulty oxygen sensor is one of the most common reasons for the check engine light to come on in a 2018 Ford Escape.

Faulty Emissions Control Part

The emissions control system in your 2018 Ford Escape is designed to reduce harmful emissions and ensure compliance with environmental regulations. However, if one of the emissions control parts becomes faulty or fails, it can trigger the check engine light. Common faulty emissions control parts include the catalytic converter, oxygen sensors, and the evaporative emission control system.

Malfunction With Fuel Injection System

The fuel injection system in your 2018 Ford Escape is responsible for delivering the right amount of fuel to the engine for combustion. If there is a malfunction in this system, it can cause a variety of issues, including rough idle, misfires, and reduced fuel efficiency. A malfunction in the fuel injection system can trigger the check engine light and should be addressed promptly to avoid further damage to the engine.

Severity Of Check Engine Light

When the check engine light comes on in your 2018 Ford Escape, it’s important to assess the severity of the issue. Understanding the severity can help you determine whether it’s safe to continue driving or if you need to address the problem immediately. Here, we’ll explore the two main types of check engine light indicators and what they mean for your vehicle.

Solid Yellow Or Orange Light

A solid yellow or orange check engine light typically indicates a lower severity issue. While it may not be an immediate cause for alarm, it’s still important to have the problem diagnosed and fixed. Ignoring a solid check engine light can lead to potential complications and costlier repairs down the line.

Some common causes for a solid check engine light in a Ford vehicle include a faulty emissions control part, dirty mass airflow sensor, damaged oxygen sensor, or a malfunction with the fuel injection system. However, these are just a few possibilities, and it’s always best to consult with a professional mechanic to accurately diagnose the problem.

When you see a solid yellow or orange check engine light, it’s recommended to schedule an appointment with your mechanic as soon as possible. They can use specialized diagnostic tools to identify the exact issue and provide a solution, ensuring the longevity and optimal performance of your 2018 Ford Escape.

Flashing Check Engine Light

In contrast, a flashing check engine light requires immediate attention and should not be ignored. A flashing light typically indicates a more severe problem that could potentially cause further damage to your vehicle if left unaddressed.

If you notice a flashing check engine light in your 2018 Ford Escape, it’s essential to pull over to a safe location as soon as possible. Continuing to drive with a flashing check engine light can result in further engine damage or a complete breakdown.

Some common causes for a flashing check engine light include a misfiring engine, a severe fuel system issue, or a catalytic converter problem. These issues require prompt professional intervention to prevent any further complications.

Contact your trusted mechanic or Ford dealership immediately if you encounter a flashing check engine light. They will be able to accurately diagnose the issue and provide the necessary repairs to get your vehicle back in optimal condition.
