What causes a check engine light to come on Dodge Durango?

Causes of a Check Engine Light in a Dodge Durango
The check engine light in a Dodge Durango can come on for various reasons. Here are some common causes:
1. Loose or damaged gas cap: A loose or damaged gas cap can cause the check engine light to come on. The gas cap acts as a seal for the fuel system and helps maintain pressure in the fuel tank. If the cap is loose or damaged, it can reduce gas mileage and increase emissions.
2. Faulty oxygen (O2) sensor: The O2 sensor measures the amount of oxygen in the exhaust system and sends data to the vehicle’s onboard computer. A faulty O2 sensor can affect fuel economy, damage the catalytic converter, and cause issues with spark plugs.
3. Engine misfire: An engine misfire occurs when the fuel-air mixture in one or more cylinders fails to ignite properly. This can be caused by issues such as a faulty spark plug, ignition coil, or fuel injector.
4. Other engine-related issues: The check engine light can also come on due to various other engine-related issues, such as a malfunctioning sensor, a problem with the emissions control system, or a problem with the engine itself.
It’s important to note that the check engine light can indicate both minor and serious problems. A steady glow usually indicates something less serious, while a flashing check engine light indicates a more serious issue that requires immediate attention.
If the check engine light comes on in your Dodge Durango, it is recommended to:
– Check if the gas cap is loose and tighten it if necessary.
– If the light persists, it is best to take your vehicle to a certified mechanic or dealer to have it diagnosed using a diagnostic test.
Please note that this information is based on general knowledge and may not cover all possible causes for a check engine light in a Dodge Durango. It is always best to consult a professional for an accurate diagnosis.
