Check Engine Light

When you’re driving and your check engine light comes on your first reaction may be to PANIC. Will I be able to make it home or to a mechanic before the engine dies? Don’t worry. The problem may not be that critical but it shouldn’t be ignored either. The Check Engine Light, also known as the Malfunction Indicator Lamp, monitors the emissions being released by your car. Emissions are the gasses released into our atmosphere that are harmful to our planet.

What is an Onboard Computer Diagnostic System?

Most modern cars are equipped with an onboard computer diagnostic system, OBD. It’s a series of diagnostic trouble codes standardized by automakers. The certified mechanics at Trustworthy Auto will perform a check engine light diagnostic test and find the problem. It could range anywhere from a loose gas cap to a misfiring cylinder. These are some of the most common problems:

  • Loose gas cap

  • Vacuum leak

  • Catalytic Converter failure

  • Oxygen Sensor failure

  • Spark Plug or bad spark plug wires

  • Ignition Coil Issues

  • Mass Airflow Sensor failure

  • Dead Battery

  • Exhaust gas recirculation valve failure

When Should I Have My Car Checked?

If your Check Engine Light is constantly on then it is mostly likely an emissions problem and needs to be tended to. If your Check Engine Light is flashing then that is a serious problem and your vehicle needs to be serviced immediately before a more severe situation arises.
