Getting the 2014 Dodge Durango check engine light on can be a scary experience. There are several different things you need to check to ensure the problem isn’t serious. These include the O2 sensor, spark plugs, ignition system, and the Vacuum system.

2014 Dodge Durango Check Engine Light: O2 Sensor

Whether you are looking to upgrade to a new car or you are a do-it-yourself type, you might be wondering about the O2 sensor on 2014 Dodge Durango. This sensor helps your Durango run more efficiently by monitoring the amount of oxygen in the exhaust gas. It sends the information to your car’s onboard computer. This data is important because it helps the computer maintain the correct air to fuel ratio in the combustion chambers.

When your Durango has an oxygen sensor that is malfunctioning, you might be seeing the 2014 Dodge Durango check engine light. This light illuminates when the data on the sensor is out of the manufacturer’s specifications. This can lead to poor fuel efficiency, increased emissions, and more frequent trips to the gas station. If you are not confident in your ability to troubleshoot an O2 sensor on your own, take your Durango to a certified mechanic to have the problem checked out.

A defective O2 sensor can cause rough acceleration, poor fuel economy, and a rotten egg odor in your exhaust. It can also cause damage to your spark plugs. Typically, a new O2 sensor can improve your Durango’s fuel economy by up to 40%.

2014 Dodge Durango Check Engine Light: Vacuum System

Depending on your vehicle’s model, there are many different systems that rely on engine vacuum. If you are experiencing performance issues with your Durango, it may be time to check out the vacuum system.

First, you need to determine whether or not you have a vacuum line. If you do, you may want to check your car’s manual or search online to see if your car has a vacuum line diagram. If it does not, you can borrow one from your local auto parts store.

In addition, you should consider purchasing a hand-operated vacuum pump. You can purchase one online or at most auto parts stores. If you choose to perform this task on your own, you may want to follow the instructions in your repair manual.

The vacuum system is made up of different sensors that send data to an electronic control unit. The 2014 Dodge Durango check engine light may come on if one of the sensors is malfunctioning.

2014 Dodge Durango Check Engine Light: Spark Plugs

Having bad spark plugs in your Dodge Durango can cause your engine to struggle. You may also notice that your fuel economy is less than optimal. If you own a Durango, you should replace your spark plugs according to the vehicle’s manufacturer’s recommendation.

In general, spark plugs should be replaced at least every 100k miles. If you are not sure how to check the condition of your plugs, you can always take your vehicle to a mechanic to have it checked.

If you have bad spark plugs, you may experience poor fuel economy, misfiring, and even engine stalling. In extreme cases, your engine may even fail to start. If you are experiencing one of these issues, it is best to take your Durango to a professional mechanic to have it diagnosed.

Depending on the engine type, spark plugs are made of copper, platinum, or iridium. They should be replaced at least every 20,000 to 30,000 miles. Modern spark plugs are affordable and can last up to 100,000 miles. If you are considering upgrading your spark plugs, look for higher quality materials that will extend their lifespan.

2014 Dodge Durango Check Engine Light: Ignition System

Having a 2014 Dodge Durango check engine light could be the sign of trouble in your Durango’s engine. It’s important to know the cause of the light and to know how to troubleshoot it. Taking it to an auto repair shop will help diagnose the problem quickly. Depending on the problem, your Durango may need a new ignition coil.

The ignition system in a Durango consists of spark plugs and ignition coil packs. Spark plugs and ignition coils work together to ignite the air/fuel mixture in the combustion chamber. It’s important to check spark plugs and ignition coils for misfires. A misfire is when a cylinder is not generating sparks and will cause poor performance.

A misfire can be caused by worn spark plugs and spark plug wires, as well as a clogged catalytic converter. This can affect the emission test results and affect fuel economy. It’s important to replace spark plugs and spark plug wires every 30,000 miles.
