Check Engine Light Ford Fusion, Focus, And Escape [Solved]
The Ford owners commonly experience the “Check Engine” light, the crucial element of the onboard diagnostics (OBD) system. It indicates that something is going wrong with your Ford when it displays. The measurement of how serious the problem is is hard; it can be as simple as a loose gas cap or something as serious as a failing catalytic converter.
However, if you’re facing the Ford check engine light issue, this guide will help you understand its meanings, causes, repair costs, and how to reset and fix this warning light. Addressing and correcting the problem promptly lets you maintain your vehicle and ensure its performance.
What Is The Meaning OF Check Engine Light Ford?
The check engine light is a yellow warning sign (shaped like an engine) that indicates the issues with your vehicle. It’s also known as the Malfunction Indicator Light (MIL), which suggests that the engine control module (ECM) has detected a fault within your vehicle systems or its components. The two types of check engine light warnings are:
- A solid check engine light Generally means that the issue with your vehicle is not immediately dangerous, but it’s always best to resolve it soon.
- Flashing the check engine light indicates that a more critical issue, like an engine misfire, can potentially damage the engine. In those circumstances, it is crucial to stop driving immediately and have the vehicle inspected as soon as possible.
Check Engine Light In Ford Vehicles: Common Causes
Several reasons can lead to Ford vehicles’ check engine light error message. Typically, most of them relate to the engine and its surrounding parts. However, some of its common causes include:
- Loose or damaged gas cap
- Catalytic converter issues
- Oxygen sensor failure
- Mass airflow sensor (MAF) failure
- Spark plug or ignition coil issues
- Faulty EGR valve
Loose Or Damaged Gas Cap
The loose or cracked gas cap is one of the most common reasons that can lead to the Check Engine light on your Ford. It is one of the crucial parts of the fuel system; if it is not sealed properly, it can cause a warning light. However, ensure your vehicle’s gas cap is properly tightened; if it’s damaged, replace it.
Catalytic Converter Issues
The catalytic converter is a vital component of the exhaust system, reducing harmful emissions such as carbon monoxide, hydrocarbons, and nitrogen oxides from vehicles. If a catalytic converter becomes clogged or damaged, it can be the reason for the Check Engine Light to appear in your Ford vehicle.
Oxygen Sensor Failure
The oxygen sensor (O2 sensor) plays a crucial role in vehicles by monitoring the oxygen level in the exhaust gases as they leave the engine and then sending this information to the engine control module (ECM) of the vehicle. Therefore, if the oxygen sensor fails, it can increase emissions and cause poor fuel efficiency.
Mass Airflow Sensor (MAF) Failure
The primary function of the mass MAF sensor is to measure the air amount that enters the engine and then provide this information to the vehicle’s ECM. The engine control model (ECM) uses that data to ensure the correct air-fuel ratio for efficient combustion.
Moreover, poor acceleration, stalling, and rough idling are some symptoms of failed mass airflow (MAF) sensors.
Spark Plug Or Ignition Coil Issues
The main function of the spark plug is to ignite the air-fuel mixture, enabling the engine to generate power. The ignition coil converts the 12-volt electrical system voltage of the vehicles into thousands of volts, which is essential for igniting the fuel-air mixture.
Faulty spark plugs or ignition coils can cause various issues like engine misfires and the illuminating of the Check Engine light on the dashboard. However, fixing or replacing the affected spark plugs and ignition coils is essential because ignoring this can harm your vehicle’s catalytic converter or engine parts.
Faulty EGR Valve
Like other components, the Exhaust Gas Recirculation (EGR) valve is also a helpful component in reducing vehicle nitrogen oxide (NOx) emissions. The check engine light warning message can be displayed if the EGR valve is clogged or faulty. Moreover, poor fuel economy, rough idling, and stalling are some symptoms of a faulty EGR valve.
Check Engine Light Ford: Diagnosing The Problem
Before fixing that problem, it’s necessary to properly diagnose the reason behind the illuminating of the check engine light. Because this is a Diagnostic Trouble Code (DTC), you need an OBD-II scanner to perform the complete diagnosis.
Most auto parts stores will offer you a scan of your car free of cost, or you can buy a scanner for later use at home.
How To Fix The Check Engine Light Issue On Ford?
Fixing minor issues like loose gas caps might be a quick and easy DIY task. In comparison, the major and complex issues like oxygen sensor failures must be a professional job. Therefore, when the root problem is diagnosed successfully, here are some DIY fixes that you can follow to fix the check engine light Ford Fusion:
- Gas Cap: If the gas cap is loose, ensure it tightens correctly, and if it is damaged, replace it. If the gas cap is the issue, the light should turn off after a few driving cycles.
- Oxygen Sensor: Replace the oxygen sensor if it is affected, but you need the right tools. Before this procedure, ensure the battery is disconnected to reset the ECM.
- Mass Airflow Sensor: You can use a special MAF sensor cleaner to clean MAF sensors. Avoid applying excessive force and use a soft touch to avoid damaging the components.
- Spark Plugs: Replacement of the faulty or damaged spark plugs is a common maintenance task that you do. Ensure the installation of the correct spark plugs according to your Ford model.
Estimated Repair Costs For Check Engine Light Issues
