Is your Dodge check engine light on? Here are 7 common reasons why it may have lit up and how to fix them.

Here are 7 common reasons why it may have lit up and how to fix them.

  1. Faulty Oxygen Sensor: One of the most common reasons for a check engine light to appear is a faulty oxygen sensor. This sensor is responsible for monitoring the amount of oxygen in your vehicle’s exhaust system and ensuring that it’s at the correct level. If it fails, it can lead to decreased fuel efficiency and increased emissions.
  2. Loose Gas Cap: Believe it or not, a loose gas cap can cause the check engine light to come on. If the cap isn’t tightened enough, it can cause a vacuum leak in the fuel system, which triggers the light. Make sure your gas cap is securely fastened, and if it’s damaged, replace it.
  3. Malfunctioning Catalytic Converter: The catalytic converter is responsible for converting harmful exhaust gases into less harmful ones. If it malfunctions, it can lead to decreased performance and increased emissions. In some cases, it may need to be replaced.
  4. Dirty Mass Airflow Sensor: The mass airflow sensor measures the amount of air entering the engine and adjusts the fuel injection accordingly. If it’s dirty, it can cause incorrect readings, which may trigger the check engine light. Try cleaning it with a specialized cleaner.
  5. Dead Battery or Faulty Alternator: If your battery or alternator is failing, it can cause the check engine light to come on. Your vehicle’s electrical system relies on a healthy battery and alternator, so if either of them fails, it can lead to a variety of issues.
  6. Failed Ignition Coil: The ignition coil is responsible for producing the spark that ignites the fuel in your engine. If it fails, your engine may misfire, and the check engine light may come on. Replacing the ignition coil is the best solution in this case.
  7. Faulty Thermostat: The thermostat regulates the engine’s temperature by controlling the flow of coolant. If it fails, your engine may overheat, which can cause serious damage. In some cases, it may need to be replaced.
