Will Advance Auto Parts Check Engine Lights? The Definitive Guide

Yes, Advance Auto Parts will check your check engine light for free. This service is offered at most of their locations as a customer courtesy, helping you diagnose potential issues before they become major problems.

Decoding the Check Engine Light Mystery: Advance Auto Parts to the Rescue

That little light on your dashboard, the ominous check engine light, can send shivers down the spine of even the most seasoned driver. Is it a minor hiccup or a catastrophic engine failure looming? Fortunately, you don’t have to face the uncertainty alone. Advance Auto Parts provides a free diagnostic service designed to shed light on the situation. But what exactly does this entail, and what can you expect? Let’s delve into the details.

The Free Check Engine Light Diagnostic: What to Expect

When you visit Advance Auto Parts with your illuminated check engine light, a store associate will typically use an OBD II (On-Board Diagnostics II) scanner to retrieve the diagnostic trouble codes (DTCs) stored in your vehicle’s computer. These codes are essentially clues pointing to the source of the problem.

The associate will then provide you with the code(s) and a brief explanation of what they might mean. This is a valuable starting point, but it’s crucial to understand that the code itself is not always the definitive answer. It indicates a potential area of concern, not necessarily the exact component that’s faulty.

For example, a code related to the oxygen sensor could indicate a failing sensor, a leak in the exhaust system, or even a problem with the catalytic converter. The code is merely a guide, and further investigation is often necessary.

Beyond the Code: What Advance Auto Parts Doesn’t Do

It’s essential to manage your expectations regarding the free check engine light service. While Advance Auto Parts will provide the diagnostic trouble codes and a basic explanation, they will not perform a comprehensive diagnostic inspection. They also cannot legally clear the check engine light in some states.

This means they won’t:

• Disassemble engine components.
• Test individual parts to determine their functionality.
• Perform advanced diagnostic procedures with specialized equipment.
• Offer repair recommendations beyond suggesting possible replacement parts.

Think of it as a quick triage. It helps identify the general area of the problem, but further diagnosis by a qualified mechanic is usually required for an accurate and effective repair.

Utilizing the Information Effectively

The information obtained from Advance Auto Parts is most valuable when used as a starting point for further investigation. Here’s how to make the most of it:

• Write down the codes and their explanations: This information will be helpful when consulting with a mechanic.
• Do your own research: Use online resources, such as automotive forums and repair websites, to learn more about the potential causes of the codes.
• Consult with a qualified mechanic: Discuss the codes and symptoms with a trusted mechanic who can perform a thorough diagnostic inspection.
• Consider the age and mileage of your vehicle: This can provide valuable context when evaluating potential problems.
• Prioritize safety: If the check engine light is flashing, or if you notice any performance issues, it’s crucial to address the problem immediately to avoid further damage.

Frequently Asked Questions (FAQs)

1. Is the check engine light service at Advance Auto Parts really free?

Yes, the basic OBD II code reading is a free service offered at most Advance Auto Parts locations. It’s a way for them to attract customers and potentially sell parts related to the diagnosed issue.

2. Do I need an appointment to get my check engine light checked at Advance Auto Parts?

Generally, no appointment is necessary. You can usually walk into any Advance Auto Parts store and request the service. However, it’s always a good idea to call ahead, especially during peak hours, to ensure availability.

3. What if Advance Auto Parts can’t read the codes from my vehicle?

This is rare but can happen, particularly with older vehicles or those with heavily modified systems. If the OBD II scanner can’t connect to your vehicle’s computer, a mechanic with specialized equipment may be needed.

4. Can Advance Auto Parts tell me exactly what’s wrong with my car based on the check engine light?

No, they can’t guarantee a definitive diagnosis. The OBD II codes provide clues, but further testing and inspection are often necessary to pinpoint the exact problem. They provide the probable area of the issue, but the final and more accurate call relies on a certified mechanic’s assessment.

5. Will Advance Auto Parts reset my check engine light after reading the codes?

In some states, Advance Auto Parts cannot legally reset the check engine light. Federal laws vary by state, so it is important to be aware of the local laws. Even if they can, it’s generally not recommended to reset the light without addressing the underlying problem. The light will likely reappear if the issue persists. The light should not be considered “fixed” until a qualified mechanic has fixed the issue.

6. What if my check engine light is flashing?

A flashing check engine light indicates a serious problem that requires immediate attention. It often signifies a misfire that can damage the catalytic converter. You should avoid driving the vehicle and consult with a mechanic as soon as possible.

7. How accurate are the OBD II codes provided by Advance Auto Parts?

The codes themselves are generally accurate in identifying a potential area of concern. However, the interpretation of the codes can be complex, and further investigation is often required to determine the root cause of the problem.

8. Can I trust the recommendations for replacement parts from Advance Auto Parts?

While Advance Auto Parts associates can suggest possible replacement parts based on the diagnostic codes, it’s always wise to get a second opinion from a qualified mechanic. They can perform a thorough inspection and ensure that the recommended parts are the correct ones for your vehicle.

9. What is the difference between a check engine light and a service engine soon light?

In most modern vehicles, the terms “check engine light” and “service engine soon light” are used interchangeably. They both indicate a problem with the engine or related systems. However, older vehicles may have used “service engine soon” to indicate a less severe issue than a “check engine” warning.

10. Will this service work for all makes and models of cars?

The OBD II standard is widely adopted, and Advance Auto Parts’ scanner should work on most vehicles manufactured after 1996. However, some older or heavily modified vehicles may require specialized diagnostic equipment.

11. Besides reading the check engine light, what other free services does Advance Auto Parts offer?

Advance Auto Parts often provides other free services, such as battery testing, battery installation (with purchase), and wiper blade installation. These services can vary by location, so it’s best to check with your local store.

12. What should I do after getting the codes read at Advance Auto Parts?

After obtaining the diagnostic trouble codes, the next step is to consult with a qualified mechanic for a thorough inspection and diagnosis. They can perform the necessary tests to pinpoint the exact problem and recommend the appropriate repairs. Don’t rely solely on the codes to dictate your next move. A professional’s expertise is invaluable in ensuring a proper and lasting solution.
