Checking the gas cap is the first step when the Check Engine Light comes on.

Common Causes Of Check Engine Light

The check engine light in your Dodge Durango can indicate a variety of issues that range from minor to more serious. It’s important to address these issues promptly to prevent further damage to your vehicle. Below are the common causes of the check engine light:

Oxygen Sensor Failure

An oxygen sensor failure is one of the most common reasons for the check engine light to come on in a Dodge Durango. The oxygen sensor measures the amount of oxygen in the exhaust gases and helps determine the fuel-to-air ratio. When the oxygen sensor fails, it can affect your vehicle’s performance and fuel efficiency. It’s essential to have the oxygen sensor replaced by a professional to restore your vehicle’s exhaust system’s proper functioning.

Fuel System Issues

Problems with the fuel system can trigger the check engine light in your Dodge Durango. These issues can include a loose gas cap, fuel leaks, or a faulty fuel pump. A loose gas cap can cause a vacuum leak and disrupt the fuel system’s proper functioning. Fuel leaks can be dangerous and should be addressed immediately. If you suspect a fuel system problem, it’s crucial to have a qualified technician inspect and repair your Dodge Durango.

Catalytic Converter Problems

The catalytic converter plays a vital role in reducing harmful emissions from your vehicle’s exhaust gases. When the catalytic converter fails, it can trigger the check engine light in your Dodge Durango. Common issues that can affect the catalytic converter include clogs, damage, or overheating. A faulty catalytic converter can lead to decreased performance and increased emissions. It’s important to have your catalytic converter inspected and replaced if necessary to maintain optimal vehicle performance and reduce harmful exhaust emissions.

Remember, when your check engine light comes on, it’s essential to have the issue diagnosed and repaired by a qualified technician. Ignoring the check engine light can result in further damage to your vehicle and potentially costlier repairs. Keep your Dodge Durango running smoothly by addressing the common causes of the check engine light promptly.
