What Does Service Engine Light Mean?

Service engine light? What does it mean? Is your car safe to drive with the service engine soon light on, or should you pull over and call for roadside assistance immediately? Let’s take a look.

Six of the most common malfunctions that cause the check engine light to come on are:

  • Loose or Faulty Gas Cap.
  • Vacuum Leaks.
  • Spark Plugs, Ignition Coils, or Ignition Wires.
  • Oxygen Sensor.
  • Mass Air Flow Sensor.
  • Catalytic Converter.

The service engine light (sometimes called the check engine or maintenance reminder) is intended as a warning. It can come on if there are any malfunctions in your vehicle’s emissions system which could seriously reduce efficiency and, in some cases, lead to more costly repairs later down the road. If it flashes it means that you need to stop driving immediately – most likely because something needs immediate attention from a mechanic but also possibly due to an unsafe condition such as low oil pressure. Some people find themselves inadvertently ignoring this flashing indicator until their entire dashboard lights up with warnings!

A car’s service engine soon light can come on for many reasons. Most of the time, it is simply a warning that you should have your vehicle serviced shortly and there is no need to pull over immediately.

However, if the check engine light flashes or stays on steadily while driving you will want to stop as quickly as possible – preferably at an auto repair shop – because something needs immediate attention from a qualified technician who will be able to tell what else may have been affected or damaged by whatever problem caused the flashing or steady bulb (a blown fuse? low oil pressure?). If your car has stalled out with its check engine light blinking then this could mean you are running dangerously low on gas and would benefit from a roadside assistance call.

For safety reasons, we recommend getting roadside assistance until you have had the problem diagnosed by a qualified technician who will be able to tell if anything else has been affected or damaged.
