What are common reasons the check engine light illuminates?
The check engine light is one of the most important warning indicators on your vehicle’s dashboard. While the light may sometimes point to a minor issue, it can also signal more serious engine problems that require immediate attention. Ignoring the check engine light can allow problems to worsen and lead to more expensive repairs. At Inland Sales & Service, we provide expert check engine light diagnostics and repair in the greater Spokane area. Here are four common reasons the check engine light may come on.
Faulty Oxygen Sensor
Oxygen sensors monitor the amount of oxygen in the exhaust system and help regulate fuel efficiency and emissions. Over time, these sensors can wear out. A failing oxygen sensor may reduce fuel-economy, increase emissions, and negatively affect engine performance. Replacing a faulty sensor promptly helps maintain proper engine operation.
Problems With the Catalytic Converter
The catalytic converter helps reduce harmful exhaust emissions produced by the engine. If the converter becomes clogged or damaged, the vehicle may suffer from reduced power, poor acceleration, and decreased fuel-efficiency. Catalytic converter problems can affect other components, such as oxygen sensors, and should be addressed ASAP.
Mass Airflow Sensor Issues
The mass airflow sensor measures the amount of air entering the engine so the computer can maintain the proper fuel mixture. When this sensor becomes dirty or fails, the engine may run inefficiently and trigger the check engine light. Drivers may notice rough idling, stalling, or reduced fuel-economy. Cleaning or replacing the sensor can often restore normal engine performance.
Malfunctioning Spark Plugs or Ignition Coils
Spark plugs and ignition coils are responsible for igniting the air-fuel mixture inside the engine cylinders. Worn spark plugs or failing ignition coils can cause engine misfires, rough idling, hesitation, and poor acceleration. Replacing worn ignition components helps restore smooth engine performance and prevents potentially bigger problems.
