What Can Cause Your 2014 Dodge Journey Check Engine Light to Blink?

Several things can cause your 2014 Dodge Journey check engine light to blink. This includes the following: ıgnition system, fuel system, O2 sensors, spark plugs and plug wires.

2014 Dodge Journey Check Engine Light: Fuel System

Whether you are a Dodge Journey owner or not, you might be worried about the 2014 Dodge Journey check engine light. Usually, the light means that something is wrong with the car’s engine. However, this light isn’t always indicative of big problems.

The 2014 Dodge Journey check engine light is part of an onboard diagnostics system, which monitors and controls many engine functions. It also identifies an issue and stores the diagnostic trouble code in the car’s memory.

There are a variety of things that trigger the 2014 Dodge Journey check engine light, such as low oil, a loose gas cap, a leaky fluid system, and more. While these problems may not be as dangerous as a faulty engine, they can still degrade your vehicle’s fuel mileage.

2014 Dodge Journey Check Engine Light: Ignition System

Whether you drive a new Dodge Journey or a used one, it is recommended that you check the ignition system on your vehicle periodically. This is because it can affect your engine performance, especially when it comes to misfires.

There are several reasons why your Dodge Journey’s ignition system might fail. One of them is moisture intrusion. If there is a leak in the spark plug tube, this can cause the ignition coils to malfunction. If you are experiencing this type of problem, you should contact a mechanic to check for a faulty connector.

Another reason why your ignition coil might fail is because your vehicle is overheating. This can happen when the coolant flow is disrupted. If you have a leak, you should replace the seal. Another reason why your Journey’s engine might overheat is if the catalytic converter is broken. This is the device that converts carbon monoxide into carbon dioxide. If it breaks, it can cause your car to emit more harmful gases, which can damage your engine.

2014 Dodge Journey Check Engine Light: Catalytic Converter

Getting a 2014 Dodge Journey check engine light on is a good indicator that your catalytic converter is not working properly. The system works by converting harmful exhaust gases into less harmful byproducts. If it’s not working properly, it can lead to poor performance, increased fuel consumption, and a clogged catalytic converter.

The catalytic converter is located between the intake manifolds and the exhaust system. Catalytic converters are a standard feature of most domestic automobiles, and have been for over 40 years. They are designed to last for ten years or 100,000 miles. However, all converters eventually fail. They fail for a number of reasons.

Catalytic converters are expensive parts. They can fail for many reasons, including overheating, physical damage, and contamination. They also can be damaged by using leaded gasoline. A broken or clogged catalytic converter can lead to poor performance, reduced fuel efficiency, and an engine that runs very slowly.

2014 Dodge Journey Check Engine Light: Ignition Coils

Whenever you have trouble starting your 2014 Dodge Journey, you might have to check your ignition coils. These are located on the engine block and respond to a variety of signals from the fuel system and the gas pedal. A broken ignition coil can cause misfires and other problems.

The ignition coils in your Dodge Journey are responsible for transforming low battery voltage into high voltage pulses, which the spark plugs use to produce a spark. The coils also work to help the engine mix air and fuel.

Using a diagnostic scanner can help diagnose problems with the ignition coils. The scanner can read error codes, which will help you determine if the problem is caused by a faulty coil or a related system.

2014 Dodge Journey Check Engine Light: O2 Sensors

Having a faulty 2014 Dodge Journey O2 sensors can cause problems in your vehicle. These include high fuel consumption and emissions, poor acceleration, stalling and rough idling. In addition to the performance issues, a faulty sensor can also damage your catalytic converter, which can cost thousands of dollars to repair.

Oxygen sensors have a limited lifespan. If your vehicle has more than 100,000 miles, it’s time to replace your O2 sensor. If you’re unsure about whether your sensor is defective, you should take your vehicle to a mechanic for a diagnostic test.

Oxygen sensors work by measuring the oxygen content of exhaust gases. They send information to the engine computer, which in turn adjusts the air-fuel mixture. This can help you improve fuel efficiency by up to 40 percent.

2014 Dodge Journey Check Engine Light: Spark Plugs and Plug Wires

Using the right Spark plugs and plug wires for your 2014 Dodge Journey can help you maintain your vehicle’s performance. Modern spark plugs ignite an air/fuel mixture and can last up to 100k miles.

If you’re not sure whether your spark plugs are faulty, you can get an expert to take a look. Bad spark plugs can affect acceleration and fuel economy. They also can damage the catalytic converter. Symptoms include poor acceleration, decreased fuel economy, and hard starting.

Spark plugs can be copper, platinum, or iridium. Platinum plugs are more expensive than copper, but they last longer. Iridium plugs have a tip that is made of fine iridium and last for around 100,000 miles. Copper plugs are cheaper, but their tips are softer and don’t last as long.
