What Can the Mercedes-Benz Check Engine Light Mean?

An illuminated check engine light doesn’t necessarily mean engine failure is imminent, but it shouldn’t be taken lightly. Otherwise, you could run into problems with performance, fuel economy, emissions control, and more. Here’s a short list of what could be wrong with your vehicle when that ominous light turns on:

  • High idling or engine stalling
  • Incorrect air/fuel mixture
  • Ignition timing problems
  • Battery or charging problems
  • Engine overheating
  • Low oil pressure
  • Malfunctioning oxygen sensor
  • Malfunctioning catalytic converter
  • Broken mass airflow sensor
  • Faulty spark plugs and wires

Regardless of whether you suspect a broken oxygen sensor or a dying battery, you should schedule your Mercedes-Benz check engine light diagnosis at Mercedes-Benz of Honolulu as soon as possible.

Whether your check engine light has gone out, is blinking, or is glowing bright, there’s something wrong with your vehicle. Even if the check engine light goes away on its own, the problem may still need to be resolved.
