Just like any vehicle, the Dodge Durango can experience some mechanical issues over time. One of which is related to faulty coil packs in its ignition system.
The coils generate an electric current that powers the spark plugs and provides enough energy for fuel inside your engine to ignite. Without sufficient electricity, however, expect unfortunate results such as misfires or even stalls due to lack of proper combustion.
Are you looking for a comprehensive guide to Dodge Durango coil pack issues? We'll unpack the most common problems that owners experience, including symptoms of failure, root causes, and potential solutions. Read on to discover everything you need to know about Dodge Durango coil pack malfunctions.
Learning the typical symptoms of a bad coil pack in a Dodge Durango is essential for knowing how to properly fix it.
There are some tell-tale signs that something went wrong:
Whenever the engine misfires, it sends a signal to the computer, and at the same time a light indicator goes on to warn you about a malfunction. If you see a Check Engine light on the dashboard, it can be related to bad ignition coils.
Checking the condition of your ignition coils is as simple as taking off the cover and examining them for any cracks, breaks, or other visible signs of wear.
A failed coil pack can cause your Dodge Durango to not respond as expected when you're pressing the gas pedal and it may take longer to reach your desired speed. Bad ignition coils are unable to supply the engine with sufficient amount of power.
Owners of Dodge Durangos may experience rough idling as a result of bad ignition coils. The engine will not run smoothly and can cause vibrations in the cabin. This can be a major indicator that the ignition coils need to be replaced or serviced to ensure the car is running correctly.
If your Dodge Durango shows poor fuel economy, it may be a sign to check spark plugs and ignition coils. These components are key to maximizing fuel efficiency, so regular monitoring should be part of your car maintenance routine. Ensuring that the spark plugs and coils are in top shape will help maintain peak engine performance.
With extended use, the viability of the ignition coils in an Durango will likely diminish. This is caused by their decreased efficiency and strain as they work extra hard to ignite the engine The result may be prolonged time spent trying to start engines and other maintenance requirements that could have been avoided if addressed earlier.
If your Durango's ignition coils are not working properly, it is unlikely that your vehicle will be able to start. Without the proper ignition energy created by spark plugs, there won't be enough power for the successful combustion of fuel and air mix in the engine. To ensure the smooth operation of this process, it is imperative to check all components including fuel supply lines, coils and electronic systems.
The most obvious thing you can do is to inspect bad coil packs visually. Look for any signs of damage or worn out components such as cracks, corrosion or exposed wires.
If the damage is not visible, try another approach. An OBD2 scanner needs to be connected to a vehicle in order to conduct further diagnostics. If any error code from P0300 - P0312 appears, it indicates that there are misfires occurring within the engine. There is still potential for no error codes.
There are many possible culprits behind making your Dodge Durango coil pack to go bad. Besides simply wearing out over time, coils can suffer from:
The oxidation can lead to decreased fuel efficiency, increased emissions and decreased performance from the engine - all of which can lead to costly repairs. Replacing a failed coil pack with a new one is essential in order to keep your Dodge Durango running at its peak performance.
For an Dodge Durango, a leaking spark plug tube can be disastrous for the ignition coil, risking damage and misfiring. Oftentimes, this is due to a faulty seal in the valve cover of the spark plug tube - so replacing it with a new one would be your best course of action.
Finding bite marks under the hood of your Durango is an indication that a rodent may have caused damage in the engine compartment. It is essential to check all cables and hoses, particularly electrical wires and their connectors for the ignition coils, for any signs of destruction. Even small punctures can affect the performance of your engine and it's important to be thorough when inspecting the engine bay.
The ignition coils of the Dodge Durango need electricity in order to work. In the event that the fuse connected to the circuit is faulty, this will interrupt the flow of electricity and will cause the coils not to fire. It is important to check your vehicle's owners manual or the fuse box cover in order to locate which exact fuse needs to be replaced if it has blown. When replacing a fuse, be sure it is with one that has the correct amp rating for your vehicle.
