Common Causes Of Check Engine Light

The check engine light in your 2017 Silverado can be your car’s way of telling you that something isn’t quite right with its systems. It’s important to address the issue promptly to avoid potential damage and costly repairs. Here are some common causes of check engine light that you should be aware of:

Oxygen Sensor Failure

An oxygen sensor failure is one of the most common reasons why the check engine light may come on. The oxygen sensor measures the amount of unburned oxygen in your vehicle’s exhaust system and provides data to the engine control unit (ECU). A failing or faulty oxygen sensor can cause a decrease in fuel efficiency and an increase in harmful emissions. If left unaddressed, it may lead to further damage to the catalytic converter or other engine components.

Loose Gas Cap

A loose gas cap is a surprisingly common reason for the check engine light to illuminate. The gas cap plays a crucial role in maintaining proper pressure within the fuel system. If it is loose, damaged, or missing, it can trigger the check engine light. Checking and tightening the gas cap is a simple fix that you can do yourself. However, if the light remains on after securing the gas cap, there may be another underlying issue.

Catalytic Converter Issues

The catalytic converter is responsible for reducing harmful emissions by converting harmful gases into less harmful ones. Issues with the catalytic converter, such as clogging or failure, can trigger the check engine light. A faulty catalytic converter can lead to decreased engine performance, increased fuel consumption, and even engine damage if not addressed promptly.

Spark Plug Or Ignition System Problems

The spark plug and ignition system play a crucial role in the combustion process of your vehicle’s engine. If there are problems with the spark plugs, ignition coils, or spark plug wires, the engine may misfire, resulting in decreased performance and an illuminated check engine light. Ignoring these issues can lead to further damage to the engine and other components.

It’s important to note that these are just a few common causes of the check engine light in your 2017 Silverado. There can be various other reasons why the light may come on, and it’s always recommended to consult a qualified mechanic for a proper diagnosis and repair.

What To Do When The Check Engine Light Comes On

When the dreaded check engine light comes on in your 2017 Silverado, it can be a cause for concern. However, there’s no need to panic. The check engine light is simply a warning sign that something may be wrong with your vehicle. Taking the right steps when this happens can help you diagnose and resolve the issue efficiently. In this guide, we’ll walk you through the process of what to do when the check engine light comes on.

Checking The Gas Cap

Believe it or not, something as simple as a loose or damaged gas cap can trigger the check engine light. Therefore, the first thing you should do when the light comes on is to check the gas cap. Ensure that it is securely tightened. If you notice any damage, such as cracks or missing seals, consider replacing the gas cap and see if the check engine light turns off.

Diagnosing The Issue

If checking the gas cap doesn’t resolve the issue, it’s time to dive deeper and diagnose the problem. While there are countless reasons why the check engine light may come on, some common culprits include faulty oxygen sensors, issues with spark plugs or ignition coils, and even problems with the catalytic converter.

To get a better understanding of what might be causing the check engine light, it’s best to consult a professional or use an OBD-II scanner. These devices can read the diagnostic trouble codes (DTCs) stored in your vehicle’s computer system, which will give you more information about the specific issue.

Resetting The Check Engine Light

Once you have diagnosed and resolved the issue causing the check engine light to come on, you’ll want to reset the light. This step is crucial because it allows you to verify that the problem has been fixed and that the light won’t come back on.

To reset the check engine light on your 2017 Silverado, follow these simple steps:

1. Locate the OBD-II port, which is usually found beneath the dashboard on the driver’s side.
2. Plug your OBD-II scanner into the port.
3. Turn on the ignition without starting the engine.
4. Follow the prompts on your scanner to access the clear codes function.
5. Select the option to clear codes and wait for the process to complete.
6. Disconnect the scanner and start the engine to ensure the check engine light is no longer illuminated.

Keep in mind that resetting the check engine light does not fix the underlying issue. It is merely a way to confirm that the problem has been resolved. If the light comes back on after resetting it, you may need to further investigate or seek professional help to address the problem.

In conclusion, when your 2017 Silverado’s check engine light comes on, remain calm and follow these steps: check the gas cap, diagnose the issue using an OBD-II scanner, and reset the light to ensure the problem is resolved. By doing so, you’ll be on your way to keeping your Silverado running smoothly and efficiently.
