Seeing the check engine light illuminate on your dashboard can be unsettling, especially when your vehicle seems to be driving normally. This warning light can be triggered by something relatively minor or by a problem that requires immediate attention. Because the light can indicate numerous potential issues, it's important not to ignore it. At Dream Motors LLC, we provide expert check engine light diagnostics and repair in the greater Ramsey, MN area. Here are four of the most common triggers of the check engine light. Worn Spark Plugs Spark plugs are responsible for igniting the air-fuel mixture inside gasoline engines. Worn or damaged spark plugs can cause misfires, rough idling, and hesitation. Engine misfires can trigger the check engine light, sometimes accompanied by noticeable shaking or poor acceleration. Replacing worn spark plugs according to the manufacturer's recommendations can help maintain proper engine operation. Failing Oxygen Sensor Oxygen sensors monitor the amount of oxygen in the exhaust and provide information that helps the engine control its air-fuel mixture. A failing sensor can contribute to reduced fuel-efficiency and increased emissions. A diagnostic scan can help determine whether a faulty sensor is responsible for the warning light. Catalytic Converter Problems The catalytic converter helps reduce harmful emissions in the exhaust. When it becomes damaged, clogged, or inefficient, the vehicle's computer may detect a problem and illuminate the check engine light. A failing catalytic converter may also cause reduced performance, poor-fuel economy, and a smell similar to rotten eggs. Mass Airflow Sensor Problems The mass airflow sensor measures the amount of air entering the engine so the vehicle's computer can determine the appropriate amount of fuel to deliver. If the sensor becomes dirty or fails, the engine may run poorly and the check engine light may illuminate. Symptoms can include rough idling, hesitation, reduced acceleration, and changes in fuel-economy. Professional diagnostics can determine whether the sensor is causing the problem.
