Be sure to check the gas cap and make sure it is tight,it will take a trip or two to reset the light but it is more than likely an evap code.
Service required is the oil change reminder. Service engine soon would be the check engine light.
Reasons the service engine light does not come on: The bulb is burned out. I would suspect this first. There is a wiring problem. The engine control module is bad.
That is one of many possible causes.
this is caused by the sensor tripping in the light sensor to see what causes this you must diagnose it with a computer and see what fails in it.
No it will not.
A Service Engine light and a Check Engine light have the same purpose - to alert the driver that a malfunction has been detected by a sensor(s). It would behoove you to take your vehicle to an auto parts store (AutoZone or similar) that does free scans and have the touble code(s) retrieved to find what made the light come on. Some manufacturers call it a Check Engine light and others call it a Service Engine light, but as mentioned above they serve the same pirpose. I don't think your vehicle would have it labeled both ways.
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?
Low coolant would be because the coolant is low or the sensor has failed, Check engine light would be because the computer has detected a problem and set a code.
The owners guide for my '04 Endeavor says do not disconnect the battery I think, or the on board diagnostic record will be lost. maybe this would also clear the service engine light?
service engine soon is your car telling you that you have reached a pre set service interval. Check your owners manual for a list of these maintenance items.
Could be a wiring issue or a completely different 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.
If the check engine light is on with no codes, you have a wiring or computer issue.
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.
The red Check Engine light and the amber Service Engine Soon light serve the same purpose. It is unlikely that a vehicle would have both. The trouble diagnostic codes have to be retrieved in order to determine if the problem is performance or emmissions related.
You may have an electrical fault code. Have the codes read by a service tech.
Possibly, but not likely. Have a compression test run.
First I would check the gas cap. If it's not tightened until it clicks several times it can make the check engine light come on.
its missing 4 cylinders sir!
unless the battery has been disconnected, a history of previous codes is retained in memory and you will be able to tell why your service engine light was on earlier. disconnecting the battery erases all codes - you would have to wait until service engine light comes on again to read any recent codes. good luck!
Not usually....No. Take it in to AutoZone and have them check the codes for you.
It's probably misfiring. You would need to diagnose why.
make sure your gas cap is on tight. sometimes this will make your check engine light come on.
If the service light comes on it usually mean there is maintenance needed to be done elsewhere than the engine. Try making sure all your lights work including break lights, turn signals head lights, parking lights, etc.
