What is my CHECK ENGINE or SERVICE ENGINE SOON light?

All modern vehicles are equipped with an onboard computer diagnostic system (OBDII) that constantly monitors your vehicle’s major operating systems and most importantly the power-train (engine and transmission). The main purpose of monitoring these systems is to insure that the vehicle is operating at top efficiency with the lowest possible emissions. As fuel economy and emission control has become increasingly important and complex, your vehicle’s electronics systems need to constantly adjust and fine-tune various parameters according to driving conditions (such as vehicle load, temperature, and air/fuel mix to name just a few). When the computer reads that any of these parameters do not fall within the acceptable range for operating the vehicle, your CHECK ENGINE LIGHT is lit to warn you that you may have a serious problem and to take your vehicle to a certified technician – such as your local AAMCO Boardman technician – to check the faults and restore it to manufacturer’s specifications.

Don’t Hesitate To Bring Your Vehicle In

When you bring your car to AAMCO Boardman, OH, our experienced Auto Service Professionals will perform on-board diagnostics and determine why your check engine light (service engine soon) is on or flashing. While it’s impossible to say exactly why a check engine light is on or flashing without being able to examine the vehicle and perform a car diagnostic, possible causes of a steady or flashing check engine light can include:

  • Failing oxygen sensor
  • A loose gas cap
  • Bad spark plug/ignition coil
  • Bad spark plug wires
  • A problem with your catalytic converter
  • Bad mass air flow sensor
  • Engine vacuum leak
  • EGR valve problem
  • Excessive gas consumption or release of air pollutants
