Common Causes of Check Engine Light
The Check Engine Light (CEL) in your 2014 Subaru Outback can illuminate for a variety of reasons, indicating that your vehicle requires attention. Below are some of the common causes that may trigger this warning light:
| Cause | Description |
|---|---|
| Loose Gas Cap | A loose or damaged gas cap can cause fuel evaporation and trigger the CEL. Ensure that the cap is tightened properly. |
| Oxygen Sensor Malfunction | The oxygen sensor monitors the exhaust gases; a faulty sensor can affect fuel efficiency and emissions. |
| Faulty Catalytic Converter | If the catalytic converter malfunctions, it can hinder exhaust flow and increase emissions, causing the CEL to illuminate. |
| Mass Airflow Sensor Issues | This sensor ensures the correct amount of air-fuel mixture for optimal engine performance. Problems can lead to poor engine performance. |
| Ignition System Problems | Issues with spark plugs, ignition coils, or wiring can prevent your engine from firing properly, causing the light to turn on. |
If your Check Engine Light comes on, it’s essential to perform a diagnostic check as soon as possible to avoid further damage to your vehicle. Always consult the owner’s manual or visit a certified Subaru mechanic for professional advice.

- Innova 3100j – An affordable and user-friendly option that offers DTC reading for both the engine and transmission.
- Actron CP9690 – Known for its multi-system diagnostics, it can help troubleshoot various systems in the Subaru Outback.
2. Subaru-Exclusive Diagnostic Tools
While generic scanners are useful, Subaru vehicles often have unique diagnostics. Using tools designed specifically for Subaru can provide deeper insights. The Subaru Select Monitor is a comprehensive tool used by dealerships that allows for in-depth analysis of the vehicle’s systems.
3. Multimeter
A multimeter is essential when troubleshooting electrical issues. It’s useful in checking battery voltage, testing sensors, and confirming the integrity of electrical circuits that contribute to your Subaru’s performance.
4. Code Reader App
For tech-savvy Subaru owners, mobile apps such as Car Scanner and Torque Pro can be paired with Bluetooth OBD-II adapters to display engine data and DTCs directly on your smartphone. These apps offer user-friendly interfaces and instant data at your fingertips.
5. Professional Diagnostic Service
If you’re still unsure about the cause of the flashing lights or prefer a professional touch, taking your Subaru to an authorized dealer or a qualified mechanic is always a good choice. They use advanced diagnostic tools and have the expertise to troubleshoot your vehicle effectively.
Each of these tools has its strengths, so determining the right one for your needs will help you address the check engine light and flashing brake light effectively. Always remember, timely diagnostics can save you from more significant issues down the road.
Troubleshooting the Check Engine Light
The Check Engine Light (CEL) is an essential part of your vehicle’s diagnostic system. When it lights up, it’s often an indication that something isn’t quite right. Specifically for the 2014 Subaru Outback, addressing this warning promptly is crucial to avoid further damage. Here are some common troubleshooting steps you can take:
- Check the Gas Cap: One of the most frequent causes of the CEL is a loose or damaged gas cap. Make sure it is properly secured and isn’t showing signs of wear.
- Inspect the O2 Sensors: If the oxygen sensors are malfunctioning, they can cause increased emissions and affect fuel efficiency. Consider having them checked.
- Monitor the Engine Performance: Is there any noticeable change in how the engine runs? Poor acceleration or stalling may indicate a serious issue.
- Check for Diagnostic Codes: Utilize a diagnostic tool to scan for error codes. This can help pinpoint the exact issue causing the light to illuminate.
If the CEL remains on after taking these steps, it might warrant a visit to a qualified mechanic. Remember, ignoring the warning could lead to expensive repairs down the road.
Regular maintenance and prompt responses to warning signals can significantly extend the life of your vehicle.
Stay alert for other potential dashboard warning lights, such as the brake light flashing, as they can indicate additional problems that need immediate attention.
Brake Light Flashing – What it Indicates
If you notice that your brake light on your 2014 Subaru Outback is flashing, it’s essential to take it seriously. A flashing brake light can indicate several issues ranging from minor to critical. Here are some common reasons why your brake light might be flashing:
- Brake Fluid Level Low: One of the most common reasons for a flashing brake light is a low brake fluid level. Check your brake fluid reservoir and ensure it is filled to the recommended level.
- Brake System Malfunction: A malfunction in the braking system, such as issues with the brake pads, rotors, or calipers, can trigger the brake light. It’s crucial to get this checked immediately.
- Anti-Lock Braking System (ABS) Issues: If there are problems with the ABS, the brake light may flash. This could require scans with a diagnostic tool to identify the issue.
- Worn Brake Pads: Brake pads that are worn out can also activate the warning light. It’s advisable to change them before they cause more significant issues.
- Electrical Issues: Sometimes, a faulty sensor or electrical connection can trigger the brake light. Inspecting the electrical system might be necessary.
When your brake light is flashing, it serves as a warning that something may be wrong with your braking system. It is vital to address the issue immediately, as this can affect your vehicle’s safety. Ignoring it may lead to further damage or, worse, a brake failure while driving.
Make sure to have a qualified technician perform a thorough inspection. Keep in mind that regular maintenance and checks are essential for the longevity of your vehicle’s brake system.
How to Address Flashing Brake Light
A flashing brake light in your 2014 Subaru Outback can indicate a variety of issues that need immediate attention. Ignoring this warning could lead to significant safety concerns or further damage to your vehicle. Here are some steps to properly address a flashing brake light:
- Check the Brake Fluid Level:
One of the most common reasons for a flashing brake light is low brake fluid. Open the hood and locate the brake fluid reservoir. If the fluid is below the minimum level, top it up with the recommended type.
- Inspect the Brake Pads:
Worn or damaged brake pads can also trigger the brake light. If you hear a grinding noise or feel a difference in braking performance, have your brake pads inspected and replaced if necessary.
- Examine the Brake System:
Look for any visible leaks or damaged components in the brake system. If you see any signs of wear or leaks, consult a mechanic.
- Check the Electrical Connections:
A faulty electrical connection can cause the brake light to flash. Inspect the wiring and connectors for any signs of damage or corrosion.
- Consider the ABS Warning:
If the brake light is flashing alongside an ABS warning light, there may be an issue with your Anti-lock Braking System (ABS). This requires immediate professional attention.
Always prioritize safety when you see a flashing brake light. If you’re unsure or unable to resolve the issue, it’s best to consult a qualified mechanic to avoid any potential hazards.
