Check Engine Light Service in San Antonio

Our Check Engine Light process

When you bring your car to us 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
