Identifying and fixing your 2015 Dodge Charger check engine light codes can be done in a few simple steps. Some of the more common problems causing this issue include the following:
2015 Dodge Charger Check Engine Light Codes: Mass Airflow Sensor
Having a 2015 Dodge Charger check engine light on could be a sign that your Mass Air Flow Sensor has gone bad. This sensor is a key component of the intake system. It helps the engine achieve the best possible air-fuel mixture. Without a correct mixture, your fuel mileage could suffer.
The best way to test your MAF sensor is to find a certified mechanic. A trained mechanic should be able to diagnose your problem and recommend a solution.
A bad MAF sensor could cause erratic idling, poor engine performance, and excessive fuel consumption. The sensor is also responsible for delivering the appropriate air/fuel mixture to the engine. When it malfunctions, the ECM will receive incorrect values for the mixture.
Luckily, a mass air flow sensor is not expensive. You can purchase one at a parts store or at your local auto repair shop. It is best to clean it every six months or so.
2015 Dodge Charger Check Engine Light Codes: Spark Plugs
Keeping your 2015 Dodge Charger running at its best involves regular maintenance. Checking your spark plugs is a good way to do this. They may wear out after a while, which will lead to poor fuel economy and an overall reduction in performance.
If you haven’t been replacing your spark plugs, you could be damaging your engine. This can lead to poor gas mileage, a misfire, and even a clogged catalytic converter. It’s best to have a mechanic do this for you.
You should be able to tell if your spark plugs are bad by looking at the surface of the spark plug. If there is a cinder-like deposit on the surface, it means that the spark plug has been overheated. If there is a gray layer of silicates on the surface, it means that coolant has leaked into the combustion chamber.
2015 Dodge Charger Check Engine Light Codes: O2 Sensor
Using a car diagnostic tool, you can check for a faulty O2 sensor. These sensors measure the amount of oxygen in your engine’s exhaust system. This helps your engine run at optimal efficiency. However, they wear out and fail.
The best way to test an oxygen sensor is to unscrew it from its seat. After removing the sensor, you should apply anti-seize lubricant to the threads. Then, replace the sensor.
Oxygen sensors typically last over 100,000 miles in a Dodge Charger. It is best to have them checked by a professional mechanic. Faulty sensors can cause multiple fault codes.
The P0420 code is a common 2015 Dodge Charger check engine light code. This code can be cleared with a code reader. It is a symptom of a problem with your fuel/air system. This can be caused by a faulty fuel injector, a faulty exhaust gasket, a vacuum leak, or an improper air-fuel mixture.
2015 Dodge Charger Check Engine Light Codes: Ignition Coils
Having trouble with your ignition coils can cause in your 2015 Dodge Charger check engine light on? If you’ve checked the spark plugs, the plug wires and the wire connectors, but haven’t had success, there’s a good chance your coils are at fault. The good news is that you can often fix the coil problem yourself.
The first thing you can do to troubleshoot an ignition coil problem is to replace the coils. You can do this in the engine bay. You may have to remove the spark plug and connect a spark plug gapper to restore the proper spark plug spacing.
Another way to test your ignition coils is to check the resistance of the coils. You can do this with a multimeter. But you’ll have to remember that you can’t accurately measure the coil during operation.
Reset The 2015 Dodge Charger Check Engine Light
Having your check engine light on can be an annoying and potentially dangerous condition. But what does it mean and how do you clear it?
The check engine light is part of an onboard diagnostics (OBD) system that keeps track of your vehicle’s health. When a problem is detected, the onboard computer will store a trouble code. This code will help to narrow down the issue. Once you fix the issue, the computer will recognize it and the check engine light will go off.
Fortunately, there are a few ways to clear the check engine light. You can do this yourself, or you can have a mechanic do it for you.
Most do it yourselfers can purchase an inexpensive code reader and connect it to the onboard diagnostics port in your vehicle. After connecting the reader, you can see error codes and erase them. Some of the more advanced code readers will also allow you to turn off the check engine light.
