Subaru Outback Check Engine Light Flashing – Causes, Symptoms, and Possible Fixes

A faulty brake light on your Subaru Outback can be dangerous and may require professional help. It may be easy to replace the brake light yourself, but if it’s a faulty one, it could cause further damage to your Subaru. In this article, you will learn how to detect the problem and how to repair it. Read on to learn the cause, symptoms, and possible fixes.


If you notice that your Subaru Outback’s check engine light is blinking, it may be a sign that your car is experiencing a malfunction. Thankfully, there are a few simple ways to troubleshoot this problem, and once you’ve solved the underlying cause, the light should go out and continue flashing for another 20 or 40 miles. Listed below are three of the most common causes of a flashing check engine light and how to fix them.

Brake and ABS braking systems are both similar in the way they work, and so they’re linked. If either of these systems malfunction, you can easily resolve this problem by changing the faulty component and turning off your car. If neither of these steps fixes the issue, you’ll want to take your Subaru Outback to a mechanic, who will fix it correctly and give you the peace of mind that you deserve.

A malfunctioning brake system is another common cause of a flashing Subaru Outback brake light. The cruise control unit automatically regulates your vehicle’s speed, and when it malfunctions, the warning light will flash. If you can’t find the culprit, disabling cruise control is a simple fix. If that doesn’t fix the problem, you can take your car to a mechanic to have it checked.

If your Subaru Outback check engine light is blinking, or your car is having trouble starting or idling, the problem could lie in your vehicle’s mass airflow sensor. The MAF measures air entering the engine, and controls the amount of fuel that gets to it. The mass airflow sensor helps the engine manage air intake and exhaust, and helps it adjust to changes in altitude. If you see a high idle RPM, a faulty vacuum hose may be the source of the problem.

While it can be confusing to deal with this problem alone, it’s important to remember that the check engine light is not a diagnosis of the problem. A fault code will tell you what’s wrong with your vehicle. If the code is flashing, the auto part store will scan your car’s computer system for free. If you have the fault code, you can post back to let us know how to fix it.


You may have noticed that your cruise control and check engine lights come on at the same time. The traction control light may be on and the engine light is on, but you may not know why they come on. A simple fix can be to replace a burned out fuse in the cruise control module. The traction control system is part of the engine management system, and if it malfunctions, the cruise and traction controls will be disabled.

Another common reason for this warning is a faulty wheel-speed sensor. A malfunctioning wheel-speed sensor can cause the traction control light to intermittently flicker. However, if the TCL light keeps flashing, the issue could be more serious. To avoid further damage, replace the wheel-speed sensors in the traction-control module. After performing the repair, if you notice that the TCL light keeps flashing, it’s time to get it checked out.

The first thing to do is determine what is causing the check engine light to flash. Generally, a vehicle’s check engine light comes on when a problem is detected in the engine. If it’s the engine that’s causing the flashing light, it’s a problem with the engagement system. Alternatively, the problem might be with the engine itself. If the check engine light is flashing frequently, it means the engine has been experiencing too many misfires. If this is the case, you’ll need to go to the mechanic as soon as possible.

The second cause of check engine light flashing is an underlying issue with your vehicle’s electronics. Your car’s on-board diagnostic system is made up of countless electronic components. The module continuously scans for parameters out of range, including bad fuel injection and misfire. Occasionally, the sensor will indicate that something is amiss. In this case, the vehicle must be towed to a repair shop.

In some cases, it’s a matter of replacing the entire engine, which can cost you at least $4,000. Alternatively, the check engine light might flash while you are accelerating. If this is the case, you may need to replace the idle air control valve, which reads whether air is mixed with fuel. If you don’t have access to a mechanic, you can purchase a code reader for under $200.


If your Subaru Outback is experiencing a check engine light flashing problem, you may be able to solve it yourself. There are many ways to solve this issue, but here are some possible solutions:

First, check if your car is still under warranty. This problem is usually caused by a faulty throttle position sensor, and should be repaired by a mechanic. In many cases, it can be easily fixed by following the steps in this article. You’ll be surprised to learn that the problem is so simple! If you’re having trouble determining which parts of your Subaru Outback have malfunctioned, check with the manufacturer to find out which ones have the most common causes.

In addition, you may need to replace the brake lights. Sometimes, they’re defective, and can cause major damage. Luckily, it’s relatively easy to fix this problem yourself. Make sure to turn off your car before you attempt any of these fixes. If you’re not confident enough to try this, you should seek assistance from a Subaru Outback repair mechanic.

The second fix for a Subaru Outback check engine light flashing is to disengage the cruise-control function. This feature is essential for safety, and driving a Subaru Outback with a malfunctioning cruise-control unit can be dangerous. Thankfully, there are a few solutions to this problem that you can try at home. This article is not a complete guide, but should help you find the right one for your Subaru Outback.


If you’re wondering why the Subaru Outback check engine light is flashing, it may be related to your traction control system. Traction control is a safety feature that monitors steering stability and engages whenever it detects a loss of traction. Traction control works by detecting a loss of traction by utilizing electronic sensors in each wheel and communicating with the Power Train Control Module.

If your car has this troubleshooting procedure, you may be able to find the problem quickly and efficiently. If the troubleshooting process is not successful, you may have to replace your entire engine or seek professional help to repair the car. To fix the problem, you must first diagnose the underlying cause. If you are driving too fast or too slowly, the fault may be due to a worn-out spark plug.

Another common problem involving the Subaru Outback brake light is the cruise control. When the cruise control unit malfunctions, it causes the cruise control warning light to flash. Disabling the cruise control function may fix the flashing problem. If that doesn’t work, you can take it to a mechanic for further diagnostics. The flashing brake light is an indication of a serious problem.
