My little writings on radiator repair
With the already serious issues you have to deal with upon seeing the red check engine light, the last thing you need is to get into an accident! Most yellow check engine light warnings result from a problem with the electrical components of your car engine. This will cause the system to send a warning signal to the power train control module or PCM, and this is manifested as an amber check engine light. Such problems often go undetected by the car owner, since there is usually no apparent sign of any engine trouble aside from the yellow light. Of course an amber check engine light is still a serious issue to deal with, and it will still require immediate attention. Failing to get your car checked out as soon as possible may result in more serious engine or transmission related problem that will be a lot more expensive to repair.
