Common Causes Of Check Engine And Traction Light

When you’re driving your Subaru and suddenly the check engine light and traction control light come on, it can be alarming. These warning lights indicate that there may be an issue with your vehicle’s performance or safety systems. It’s important to address these issues promptly to prevent further damage and to ensure your safety on the road. In this blog post, we’ll explore the common causes of check engine and traction light on Subaru, including faulty wheel speed sensors, low tire pressure, faulty traction control system, and malfunctioning ABS system.

Faulty Wheel Speed Sensors

One of the common causes of the check engine and traction light on Subaru is faulty wheel speed sensors. These sensors are responsible for monitoring the rotational speed of each wheel and sending this information to the vehicle’s computer system. If the sensors are malfunctioning or damaged, they may send incorrect signals to the computer, triggering the warning lights. Additionally, dirt and debris can accumulate on the sensors, causing them to malfunction.

Low Tire Pressure

Another possible cause of the check engine and traction light on Subaru is low tire pressure. When the tire pressure is below the recommended level, it can affect the performance of the vehicle’s traction control system. The low tire pressure can cause the wheels to lose grip, leading to reduced traction and stability. The vehicle’s computer detects this issue and illuminates the warning lights to alert the driver. Regularly checking and maintaining the proper tire pressure can help prevent this problem.

Faulty Traction Control System

A faulty traction control system can also trigger the check engine and traction light on Subaru. This system is designed to regulate the power and braking to each wheel, maintaining traction and stability during acceleration and cornering. If there is a malfunction in the system, such as a sensor failure or wiring issue, it can cause the warning lights to illuminate. It is crucial to have the traction control system inspected and repaired to ensure safe driving conditions.

Malfunctioning Abs System

The ABS (anti-lock braking system) is an essential safety feature in vehicles, including Subaru models. When the ABS system detects wheel lock-up during braking, it modulates the braking force to prevent skidding and maintain control. If there is a malfunction in the ABS system, such as a sensor or pump failure, it can trigger the check engine and traction light. It’s crucial to have the ABS system diagnosed and repaired promptly to ensure optimal braking performance and safety.

Impact Of Ignoring The Warning Lights

Ignoring the warning lights for the check engine and traction control on a Subaru can lead to major engine damage. It’s crucial to address these issues promptly as they could indicate faulty wheel speed sensors or other crucial safety system malfunctions.

Neglecting these warnings could result in expensive repairs down the line.

Risk Of Major Engine Damage

Ignoring the warning lights that indicate a check engine and traction control issue in your Subaru can have serious consequences, including the risk of major engine damage. These warning lights are designed to alert you to potential issues with your vehicle’s engine and traction control system. Ignoring these warnings can lead to problems such as:

• Loss of power and poor engine performance
• Overheating and potential engine failure
• Increased fuel consumption
• Damage to expensive engine components

Continuing to drive your Subaru without addressing the underlying issues can have long-term effects on the overall health and performance of your engine. This is especially true if the warning lights indicate a severe problem, such as a misfiring cylinder or a faulty oxygen sensor. In such cases, prompt evaluation and repair are crucial to preventing further damage.

Importance Of Immediate Evaluation

When the check engine and traction control warning lights come on in your Subaru, it is essential to seek immediate evaluation and diagnosis. Ignoring these warning lights and continuing to drive your vehicle can worsen the underlying problem and lead to more severe issues. Here’s why immediate evaluation is crucial:

1. Identify the root cause: Professional evaluation will help pinpoint the exact problem causing the warning lights to illuminate. This is done by connecting the vehicle to a diagnostic tool that reads the fault codes stored in the engine control unit (ECU).
2. Potentially prevent major engine damage: Identifying and addressing the issue early on can prevent it from escalating into more severe engine damage. This can save you from costly repairs in the future.
3. Ensure safety on the road: The traction control system plays a vital role in maintaining stability and control of your vehicle. Ignoring a traction control issue could compromise your safety and increase the risk of accidents, especially in adverse weather conditions or during sudden maneuvers.
4. Preserve engine performance and fuel efficiency: Addressing engine issues promptly helps maintain optimal engine performance and fuel efficiency. Ignoring warning lights can lead to decreased power, increased fuel consumption, and overall reduced performance.

Remember, resolving the issues indicated by the check engine and traction control lights is not only crucial for your Subaru’s health but also for your safety and the safety of others on the road. Don’t ignore these warning signs; seek professional evaluation as soon as possible.
