A flashing SES light means an ignition problem. A constant one means emission control. The most common emission problem is an O2 sensor. Easy to replace and not too expensive; around 60 bucks. Get the car scanned and a parts shop that will do it for free and you should have your answer.

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.

SERVICE ENGINE SOON indicator After the engine is started, the SERVICE ENGINE SOON indicator will prove out for a duration of three seconds. If the instrument cluster does not receive a message from the PCM within five seconds, the instrument cluster will illuminate the SERVICE ENGINE SOON indicator and log a diagnostic trouble code (DTC).

Servise engine soon


The pesky "Service Engine Soon" light... honestly no one could tell you without actually servicing it, but it could be anything from an dirty air filter, to a bad block or piston, or anything. A licensed mechanic should be able to tell you after looking at it.

Airbag light and service soon light


You need to take this to a shop and have the airbag system repaired as that light is indicating a fault in the airbag deployment system. The service Engine soon light could be nothing more that a reminder to change the oil but is most likely an Oxygen sensor that needs replaced.

Service vehicle soon light


Do all your exterior lights work. Including the daytime running lights. This is the service vehicle soon light and not the service engine soon light? Does the service engine light come on when you turn the key on? The service vehicle light will also stay on if the service engine light is burnt out.
