Usually a problem in the emission system. Have vehicle scanned to determine the problem
A malfunctioning sensor can cause the service engine light to stay on. A glitch in the computer can also cause the light to stay on.
Many things could cause your service engine soon light to come on. Every time you start the engine, the computer does a self-diagnostic test. If it finds any faults, it will illuminate the light. I would recomend you find an OBD ( On Board Diagnostic) tester and read the code. Autozone will perform this service for free. They will read the code and tell you what is causing your light to come on.
Not usually....No. Take it in to AutoZone and have them check the codes for you.
My service engine soon light came on a day two ago, I have driven the car about 20 miles since it came on. Today, the light just went out. The vehicle is running good. What would cause the light to come on, and why would it just go out on its own?
No.
No, low gas cannot cause a Check Engine light to turn on. There would have to be a problem within the engine or the engine wiring for that light to come on.
hard fault code What is a hard fault code?
Service required is the oil change reminder. Service engine soon would be the check engine light.
If the fuel pressure is too low that might cause the service engine light to come on and , since there would not be enough fuel pressure, might also cause a sluggish response. That could be caused by a clogged fuel filter also.
Yes it can.
If it is not speced correct for it then, yes.
Yes it would. The service engine soon light on that vehicle acts much like a check engine light on other vehicles and will come on when the computer senses a fault, like a hot temperature.
