Auto Diagnostics

The on-board diagnostics system and engine control unit in your vehicle monitor a lot of different systems to make sure your vehicle is running properly. If they get a reading that’s outside the predefined parameters it will trigger the check engine light.

The list of issues that can trigger the check engine light is quite lengthy. For instance, anything from a loose gas cap to a a bad ozone sensor can be to cause. Some other potential issues that can cause your check engine light to illuminate are:

  • A faulty sensor or EVAP Leak
  • Faulty oxygen sensors
  • Worn-out spark plugs
  • Loose hoses
  • Sticky re-circulation valves
  • Pinched or deteriorated fuel injectors
  • The need of a tune up

Check The Easy Things First:

Check to make sure your gas cap is on tightly. Tighten by making sure it clicks a couple of times. Once tight put a few miles on your vehicle to see if the Check Engine Light turns off. If the check engine light is still on head to Car Care Central and we will do a free Engine Light Scan.

One: Replace Oxygen Sensor

An oxygen sensor is a part that monitors the oxygen in the exhaust. It helps monitor how efficiently your car is burning fuel. A faulty sensor means can hurt you gas mileage and cause you to fail a State Inspection.

Two: Loose or Faulty Gas Cap

The gas cap may seem tight but there may be something wrong with the seal. When it’s loose or cracked a bad gas cap allows fuel vapors leak out and can cause problems in the highly technical fuel system off. This will reduction your gas mileage and increases emissions.

Three: Replace Catalytic Convertor

The catalytic convertor works to reduce pollution thru your exhaust gases. It converts carbon monoxide and other harmful materials into harmless compounds. If your catalytic convertor is failing, you’ll notice a decrease in gas mileage or your car will be come less responsive to acceleration.

Four: Replace Mass Airflow Sensor

The mass airflow sensor helps the car’s computer know how much fuel your vehicle needs based on throttle applied and the air coming through to the engine. A faulty Mass Airflow Sensor can cause numerous issues including increase pollution and vehicle stalling. T

Five: Spark Plugs and or Ignition Coils
