the service engine light can come on for a number of reasons. mainly something has failed, or fallen out of normal perameters. Most local parts stores, Autozone, Advance auto, Checker, offer free computer scans. 90% of the time the clerk can tell you exactly what you need, and how to fix the problem. the other 10% of the time its out of their hands, or beyond their knowledge. if the clerk does not give you a good enough answer, repost a question with the engine code or codes that the scanner picked up.

1995 suburban service engine light on Does this vehicle have both a check engine and a service engine light Just bought the vehicle and I am trying not to be too worried?

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.

What would cause the service your engine soon light to come on a 2002 Montero Sports?

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.
