That sucker will go off at almost anything. Probably not a big deal. Maybe a faulty O2 sensor or something in the emission system. I would have it checked out, it is intended to keep your vehicle in optimum working condition. If you wait it will cost more.

The service engine light could be due to a variety of things - generally not critical things either. The check engine light is a bigger problem. I've seen the service engine light come on over a blown headlight bulb. I've seen it come on over a gas cap not being screwed on tightly enough. I've seen it come on over an oxygen sensor needing to be replaced. The last time my service engine light came on I poured in some good gas cleaner from AutoZone and that took care of it. In other words, I wouldn't lose too much sleep over it. Unfortunately, you lose the use of your fog light bulbs when you turn your brights on. I hate that too - that is how GM designed it though. Also, I want to correct a previous poster. The service engine light does not come on when you need your oil changed. That would be the 'change oil' light that comes on. There is a reset button to make that light go away. In conclusion, I don't think you have as big of a problem as you think you have. People who tell you to junk your car over these kinds of things are stupid. My wife has a Mazda Protege and the service engine light came on in her car the other day - why? Gas cap wasn't screwed on tightly enough. It doesn't take much for these lights to be triggered. I've heard before that the yellow lights (like service engine soon or change oil) mean that something needs to be attended to but it's NOT critical. However, if the red lights come on (like check engine or check oil) then you had better pull over and stop the engine because something serious is amiss. I don't know if that's true or not but I do think that it makes good sense when you think about it.

Be sure and check your blinker fluid, that is the main cause of the service engine soon light coming on in a Tahoe

I have changed the oxygen sensors in the exhaust pipe and reset the light. There should be 2 sensors on the exhaust pipe and they cost about $50 each. One is under pedals about even with the firewall and the other is behind the catalytic converter. A diagnostic at Pep boys or someplace like that could pinpoint the problem. It will cost about $40 to $60 for the diagnostic. If the ox sensors are bad you will get better fuel mileage by replacing them.

Sometimes when the gas cap is not tightened all the way the light will come on. I had a '99 Tahoe and the same thing happened to me. If that doesn't work, take it to a Jiffy Lube or some place like that and have them look at it.

Disconnect the ground cable from your battery {with engine off} for 2 or 3 minutes, then reconnect and start engine.
This will reset computer and may make the light go off.
If this does not work have it checked out at a garage.
If the garage finds nothing mechanical wrong then you have a bad sensor that causes it to stay on.

This is a light to remind you that you have a GM product, I like Chevys but I know the truth also, never seen to many GM's that the service engine soon light did not come on.

Does the Tahoe have a catalitic filter (under neath on the exaust you'll see a cage) the catalitic filter may need replaced or your O2 censor may need replaced. These things are very picky and will cause your light to go off!

Take it to a dealer and let them Diagnose it. That way you know what is wrong (really) and maybe it will be under warranty. The diagnostic charge (typically less than $100.00) is well worth it to know what is wrong.
Go to Auto-Zone or some under qualified, under trained, non knowledgeable independent shop and pay for tons of parts you don't need. (& by the way I have NEVER found an aftermarket shop that correctly diagnoses engine management problems. I used to work for them, they are ignorent)

Take your vehicle to a garage and have the mechanic scan your vehicle's ECM with an OBDII scan tool.
Gone are the days when you could just jumper two pins on the diagnostic link and count the check engine light flashes....
