Service engine light is on. what do this mean ?
Vacuum lines are on the engine for several different reasons. Power Brake boosters are connected to the engine by a vacuum hose, other vacuum lines go to the emission system and other engine controls.
You can spray those hoses/line with regular carb cleaner with the engine running, and if there is a leak, you will notice the engine changes RPM's when you spray near the leak. Only do this in an open area and in short burst. The "cleaner" is FLAMMBLE, so test one area and then let it air out before moving to the next area.
Reading the OBDII engine codes may help you pinpoint the leak by saying it's small, large, or, from a specific component.
The gas cap not being tightened properly, or with debris on the seal can trigger an engine light also, check that as well.

generally you just unhook the battery for about 15 minutes and hook it back up... if you have an anti-theft radio... make sure you know the code and how to enter it.

You need to have this vehicle connected to a computerised diagnostic tool to clear this message.You may also need a service done on the engine which is why is causing this light to display...

This is most likely the O2 Sensor however, that light may also come on for a vacum leak or anyone of a number of other sensors. Take the vehicle to Auto Zone and ask them to use a code reader on it and tell you what the code is for. If the code is for O2 sensor as I suspect the part will cost about $40 and take maybe 20 minutes to replace your self. ($40 for part + 5 to 10 for the special socket) If it shows anything else you may want to take it to a mechanic to have the vehicle diagnosed.

you can buy a code reader from an auto parts store that will give you the ability to reset the check engine light, or most parts stores have one that they use on customers cars at no charge. if you ask them to read which code your car is throwing, most of them will let you hit the button to clear the code. they aren't supposed to do it themselves for some reason, but from my experience they will let you.
