What does the service engine light mean on a 2015 Ford Edge


Service Engine Soon

If the Service Engine Soon indicator light stays lit after you've started the engine, the On Board Diagnostics system (OBD) has detected a malfunction of the vehicle emissions control system. Contact your authorized dealer as soon as possible.
If indicator light is blinking, an engine misfire may be occurring, which could damage your catalytic converter. Drive in a moderate fashion (avoid heavy acceleration and deceleration), and have your vehicle serviced immediately.*
The Service Engine Soon indicator light illuminates when the ignition is first turned on (prior to engine start) in order to test the bulb, as well as indicate whether the vehicle is ready for Inspection/Maintenance (I/M) testing.
Normally, the Service Engine Soon light will stay on until the engine is cranked, then turn itself off if no malfunctions are present. However, if after 15 seconds this light blinks eight times, it means that the vehicle is not ready for I/M testing.Check this link out Gary.

Drive it real easy until you get the computer scanned for trouble codes.
The check engine light is telling you the computer has a problem with something that will affect performance and emissions, when it flashes the problem is serious and can damage the engine or engine parts.
The trouble codes will tell a mechanic what to look for and test.

Why would my service engine soon light be on


  • Hi, I can help.
  • The service Engine Light Soon light means it's time for an oil change,

  • You can turn this light off real quick by following these steps.
  1. Turn the key to ACC.
  2. Press the gas pedal down all the was three times in fairly rapid succession.
  3. The service engine soon light will begin to blink and then disappear.
  4. Turn the key to off.
  5. now start your truck.
  6. The light will now be off.
  • This should be done after every oil change.
  • All the light means is that the PCM has indicated that you have driven the required miles for an oil change. A reminder light if you will.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Service engine soon light blinking /car backfiring and missing


If your check engine light is blinking, you can take your car to Autozone, Advanced Auto or other parts house and ask them to get the engine codes. This ios a FREE service. It sounds like your camshaft positioning sensor, Cam Positioning sensor is bad. This is how comuterized systems tell where the cam and crackshaft are to set the timing. It sounds like you have timing issues.

2003 Mitsubishi Montero (full-size) check engine light is on, the engine sounds like it knocks as I accellerate and the shift diff. lights blink after driving 25 or 30 miles.


The engine is probably making a knocking sound because the oil needs to be changed or replaced. The check engine light is indicating that you will need regular dealership servicing soon, however you can still drive the vehicle but depending on mileage it will determine what services are required.
