Why is my Dodge engine light on?
If your Dodge vehicle's check engine light is illuminated, it indicates that there is an issue with the vehicle's emissions control system or other engine-related components. The check engine light, also known as the malfunction indicator lamp (MIL), is a warning signal that alerts the driver to a problem that may require attention.
Common Reasons for a Dodge Check Engine Light
There are several potential reasons why the check engine light may be on in your Dodge vehicle. Some of the most common causes include:
- Faulty Oxygen Sensor: The oxygen sensors in your Dodge's engine monitor the air-fuel mixture. If one of these sensors is malfunctioning, it can trigger the check engine light.
- Loose or Damaged Gas Cap: A loose, damaged, or missing gas cap can cause the check engine light to illuminate, as it can allow air to enter the fuel system and affect the engine's performance.
- Catalytic Converter Issues: The catalytic converter is responsible for reducing harmful emissions from the engine. If the converter is failing or has been damaged, it can trigger the check engine light.
- Ignition System Problems: Issues with the spark plugs, ignition coils, or other ignition system components can cause the check engine light to turn on.
- Engine Sensor Malfunctions: The engine control module (ECM) monitors various sensors, such as the mass airflow sensor, throttle position sensor, and crankshaft position sensor. If any of these sensors are not functioning correctly, it can trigger the check engine light.
It's important to note that the check engine light can also be triggered by more serious issues, such as a misfiring engine, a problem with the transmission, or a malfunctioning emissions control system. If the light is flashing, it typically indicates a more severe problem that requires immediate attention.
Diagnosing and Addressing the Check Engine Light
If your Dodge's check engine light is illuminated, the first step is to have the vehicle's diagnostic trouble codes read using an OBD-II (On-Board Diagnostics) scanner. This will provide information about the specific issue that triggered the light, allowing you or a mechanic to diagnose and address the problem more effectively.
Once the issue has been identified, you can either attempt to fix the problem yourself, if it's a relatively simple repair, or take the vehicle to a qualified mechanic for further diagnosis and repair. It's important to address the underlying issue as soon as possible to prevent further damage to your Dodge's engine or emissions control system.

Continuing to drive with the check engine light on can potentially cause serious damage and costlier repairs. Moreover, you will likely see diminished fuel efficiency and performance in your vehicle. You should bring your vehicle to a qualified service center as soon as possible for auto repairs or maintenance.
What is the first thing to check when the check engine light comes on?
The first thing that you should check when your engine light comes on is your gas cap. Get out of the car and check to see if your gas cap is loose or if it is cracked or damaged. If your gas cap is not on securely, you must ensure that you tighten it, or the light will just come on again.
