Billy Covington If you are a Subaru Impreza owner and you have noticed a "check engine" message on your dashboard, you are likely wondering what it means, and more importantly, how to turn it off. The check engine light in your car is an important indicator that something is wrong with the engine, but it can also be activated by minor problems that can easily be resolved. In this article, we will explain why your check engine light might be on, the consequences of ignoring it, and how to turn it off.
Why is your Check Engine Light on?
There is no one answer to this question since there are numerous reasons why a check engine light might turn on. The most common reasons for the check engine light are issues with the engine, emissions system, and transmission. Some of these include:
- A loose gas cap
- A faulty oxygen sensor
- A malfunctioning catalytic converter
- A dead battery
- A damaged spark plug
It is important to note that not all issues that trigger a check engine light will immediately affect the car’s performance. However, it is crucial to identify and resolve them as soon as possible to avoid future damages to your car.
Consequences of Ignoring the Check Engine Light
Ignoring your check engine light can have severe consequences, such as decreased fuel efficiency, reduced engine performance, and even damage to the catalytic converter. In some situations, you may even experience a complete engine failure, leading to costly repairs or, in the worst-case scenario, having to replace your vehicle.
How to Turn Off the Check Engine Light on Your Subaru Impreza
Here are the simple steps that you can take to turn off the check engine light on your Subaru Impreza:
Step 1 – Identify the Issue
The first step is to diagnose the issue that triggered the check engine light, which can be done using an OBD scanner. This scanner can help determine the Diagnostic Trouble Code (DTC) that has caused the light to turn on. Most auto parts stores offer free code scanning that you can take advantage of.
Step 2 – Fix the Issue
Once you have identified the problem, address it. Some problems may require replacement parts or professional attention. Depending on your level of expertise, you can either fix it yourself or with the help of a mechanic. Make sure to follow your Subaru Impreza’s maintenance guide for specifics on the recommended repairs.
Step 3 – Reset the Check Engine Light
Once you have fixed the issue, it’s time to reset the check engine light. You can do this by either disconnecting the battery or using an OBD code scanner. If you’re using an OBD scanner, clear the codes by navigating through the menu options as directed by the device. In some instances, removing the negative battery terminal for several minutes can also reset the check engine light. However, it is important to note that this method may reset radio presets and other personalized settings and preferences.
