Common Causes of a Check Engine Light
- Loose Gas Cap: A simple yet common cause, where fuel vapors leak out and trigger the light.
- Bad Battery or Alternator: Your vehicle’s charging system will trigger a CEL if the battery or alternator are not functioning properly.
- Faulty Oxygen Sensor: This sensor is a common failure over time, and impacts fuel economy and overall emissions.
- Catalytic Converter: A failing or clogged catalytic converter leads to decreased performance and higher fuel consumption.
- Spark Plugs: Fouled spark plugs or a bad ignition wire can cause a misfire, which negatively effects engine performance and fuel economy.
- Mass Airflow Sensor: This sensor can get dirty, causing a check engine light.
The Risks of Ignoring a Check Engine Light
- Severe Engine Damage: Minor issues can escalate, resulting in costly repairs. Although the light may be for a simple fix, ignoring it is a gamble on your engine’s health.
- Reduced Fuel Efficiency: Ignoring the light may worsen fuel consumption, making it even costlier at the fuel pump.
- Failed Emissions Test: This can prevent your vehicle from being registered in many states. Additionally, simply clearing the code may not be enough to satisfy inspectors.
- Compromised Safety: Engine issues might lead to vehicle breakdowns or compromised driving conditions, and should be addressed quickly.
