When your check engine light is on, it indicates that there may be something wrong with the vehicle’s engine.

What causes my check engine light to turn on?

Here are some of the causes for a check engine light to turn on.

  • Oxygen Sensor –  Your oxegen sensor may need to be replaced.  A bad oxygen sensor doesn’t regulate the air to fuel ratio in the engine.
  • Fuel Cap – You may need to tighten or replace the fuel cap.
  • Catalytic converter – Your catalytic converter may need to be replaced.  A sharp drop in gas mileage may also indicate your catalytic converter is having issues.
  • Ignition Coil (s) – Your ignition coils may need to be replaced. They send power to the spark plugs and make them ignite.
  • Spark Plugs – You may need to replace spark plugs or spark plug wires that ignite the air-fuel mix in your engine.
  • Mass Air Flow Sensor – You may need to replace the Mass Air Flow Sensor for fuel economy.  It regulates how much air goes into the engine.
  • Vacuum hose – EVAP System may have a faulty vacuum hose and need to be repaired or replaced.
  • Exhaust Gas Recirculation Valve or EGR Valve – The EGR helps the car run well and controls emissions.
  • Battery – Your battery may need to be charged or replaced, you may have corrosive or loose wires.
  • Thermostat – Your engine may be overheating or having extreme temperature shifts which could cause engine damage.
