Maplecrest Check Engine Light Service

  
 
Your Check Engine Light Is On - What Does It Mean?
The first thing you should check when your check engine light comes on is your gas cap. If the seal is broken due to a loose or damaged gas cap, the vapor could be leaking into the fuel-tank system, which causes the check engine light to turn on.

If your gas cap is working properly, the next thing you should check is your engine oil level. A low oil level may cause your check engine light to turn on because driving with a low oil level can cause engine damage. Refer to your vehicle owner's manual to find out how to check the engine oil.

If the gas cap and engine oil level are fine, the check engine light could mean a more serious problem, such as:
• Damaged spark plugs, wires, or coils
• Issues with the thermostat
• Malfunctioning catalytic converter
• Faulty mass airflow sensor
• Malfunctioning oxygen sensor
• Faulty exhaust gas re circulation valve

What does it mean if the light is flashing?
If your check engine light is flashing rather than staying on, the engine has either misfired or some of its cylinders aren't working correctly. This can be very dangerous and may even cause damage to the catalytic converter, which is very expensive to fix. In this case, have your vehicle serviced immediately.
