You might need to use your check engine light diagnostic tool to check if something is wrong with your car. If there is something wrong with your vehicle, the check engine light will make pulses in yellow light. You will see some codes on the screen and it identifies the problem’s source. The problem ranges from the malfunctioning sensor up to the misfiring engine. The codes can be read by using a scanner.
According to the problem, the check engine light will remain constant or blink. And if you spot something like this with your car then you need to drive your car to a professional. If the light shows the steady pulse then it is not an emergency. Still, you better make an appointment as soon as possible though.
However, if the light is blinking then it might be the indication of a serious engine misfire. Sometimes the fuel could be transferred into the exhaust dump system. If this thing happened to your vehicle, the expensive repair is required. So, if the light gets on, you must find out the serious problem as fast as possible by using a check engine light diagnostic tool for the first aid before bringing it to the car repair shop.
