With some problems with the vehicle, this light will either stay on or flash. Flashing could be a more serious problem and might need immediate attention. So if this light is on, have it attended to as soon as possible. With today’s vehicles being more advanced than their predecessor, life becomes easier when your vehicle's computer box can produce you with information as to what the problem is. Doing a simple reading with the correct machines, we will have your vehicle in pristine condition in little to no time.
Some common problems with an on-check engine light
- Gas tank cap, this could be loose or damaged seal rings. Improper pressure and mix of fuel and air.
- Air intake, the system could have a broken pipe or leaking air from the gaskets or seals. A sensor picks up the wrong readings between the air and fuel mixture.
- Mass airflow sensor. This regulates the air coming into the motor calculated by the computer box.
- Catalytic converter. Dirty or clogged converter. O2 sensor will then give a bad reading and activate the check engine light.
- Alternator output voltage. This could cause your battery charge levels to decrease and in turn not have enough power supply to the system.
- Spark plug. Having insufficient spark to the system. No spark, no fire, and no movement of the motor. Fire drives this motor and fuel mixed with air to the right ratio makes effective burning and thus driving can take place.
- Electronic problem. This could include any of the above-mentioned issues as the electronics of the vehicle power everything running and reading the car.
