There can be several reasons the check engine light turns on. In most cases, it’s not really an urgent issue. But, it does mean you’ll need to bring your car to a mechanic to address a possible malfunction, so this is one warning signal that shouldn’t be ignored.

Here are three reasons to head to a mechanic when you see the check engine light turn on in your vehicle:

  • Issue With the Oxygen Sensor: According to a study by CarMD, the most common trigger that turns on the check engine light is a faulty oxygen sensor. This is often caused by the contamination of the by-products of combustion. If it’s not replaced in time, it may cause further damage to the vehicle’s spark plugs and catalytic converter.

  • check engine lightFailing Catalytic Converter: If your catalytic converter needs to be repaired, the check engine light will come on. Converter failure is often caused by worn-out piston rings or warped engine components. Not replacing it will result in reduced car performance and poor fuel economy.

  • Faulty Ignition Coil & Spark Plugs: Ignition coil failures are caused by worn-out or damaged spark plugs, hence the need to replace them both simultaneously. Ignoring this problem may lead to reduced power and fuel economy, as well as damage to the oxygen sensors.
