Service engine soon light stays on - 2004 Mitsubishi Endeavor

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.

Was the oil changed?

Heidi if you take your Lincoln to Auto Zone they do not charge for checking out service engine soon codes.

this light may be the check engine light. it's misleading. I've seen two service engine soon lights in cars. one for check engine, one for service. have it checked with a scanner

usually, this is an ignition switch problem.

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.

My service engine soon light stays on. The vihicle shakes as it idles. It act it wants to shut off. What's the problem

The service engine soon light indicates you have a problem with the engine management system.The only way to get it to stay off is to lacate and repair whatever is not working correctly. Requires very specialized equipment. Take it to your mechanic.

the service engine light is prob due to the oxygen sensor being damaged, not replace or you having the catalytic converter taken off---just messing with you. start at auto zone and have then do a free code read then go from there. you should troubleshoot the low fluid level switch for your brake fluid. unplug it and see if the light goes off and if it doesn't jump the two terminals on the harness. oh the car will have to be running.
