2014 Subaru Outback Check Engine Light Brake Light Flashing: Causes and Solutions

Introduction

The 2014 Subaru Outback is a popular SUV known for its reliability and off-road capabilities. However, like any other vehicle, it is prone to certain issues that may cause the check engine light and brake light to flash simultaneously. This article will explore the possible causes of this problem and provide potential solutions to help you resolve it.

1. Loose Gas Cap

One of the most common causes of a flashing check engine light and brake light is a loose gas cap. To determine if this is the issue, simply check the gas cap and ensure it is properly tightened. If it was loose, tighten it securely and drive the vehicle for several minutes to see if the lights stop flashing.

2. Faulty Oxygen Sensor

Another possible cause of the check engine light and brake light flashing is a faulty oxygen sensor. Oxygen sensors measure the amount of oxygen in the exhaust gases and provide data to the engine control module (ECM) for proper fuel delivery. A malfunctioning oxygen sensor can disrupt this process and trigger the warning lights. It is recommended to take your Subaru Outback to a certified mechanic or dealership to have the oxygen sensor checked and potentially replaced if necessary.

3. Malfunctioning Catalytic Converter

A malfunctioning catalytic converter can also lead to the check engine light and brake light flashing. The catalytic converter is responsible for reducing harmful emissions, and if it fails, it can trigger the warning lights. A dealership or experienced mechanic will be able to diagnose this issue and recommend the appropriate solution, which may involve replacing the catalytic converter.

4. Faulty Ignition Coil

A faulty ignition coil may be the cause of the flashing check engine light and brake light. The ignition coil is responsible for supplying the spark that ignites the fuel and air mixture in the combustion chamber. If one or more ignition coils fail, it can result in misfires and trigger the warning lights. A professional technician should diagnose the ignition coils and replace any faulty ones.

5. Faulty Mass Airflow Sensor

A faulty mass airflow (MAF) sensor can cause the check engine light and brake light to flash. The MAF sensor measures the amount of air entering the engine and calculates the appropriate fuel-to-air mixture for combustion. If the MAF sensor is faulty or dirty, it can disrupt this process and lead to warning lights. Cleaning or replacing the MAF sensor should resolve the issue.

6. Vacuum Leak

A vacuum leak can also result in the check engine light and brake light flashing. A vacuum leak refers to an unintended loss of vacuum pressure within the intake manifold, which can cause various engine performance issues. Common symptoms of a vacuum leak include rough idle, reduced power, and illuminated warning lights. A professional technician can identify and repair any vacuum leaks present.

7. Electrical System Issues

Electrical system issues, such as a faulty alternator or battery, can cause the check engine light and brake light to flash. If the lights are flashing and you notice other electrical problems, such as dimming headlights or a weak battery, it is worth checking the electrical system’s condition. The battery and alternator should be tested, and any faulty components should be replaced.

Conclusion

Experiencing a flashing check engine light and brake light in your 2014 Subaru Outback can be concerning, but it is essential to diagnose and address the problem promptly. The causes mentioned in this article are common culprits, but it is always a good idea to consult a professional technician for accurate diagnostics and repairs. Remember to regularly maintain your vehicle and address any warning lights promptly to ensure a safe and reliable driving experience.
