It will not go off by itself,you will need to reset it by connecting to a diagnostic tool.Once cleared if there is any other problem then it will trigger the check engine light again.Hope this helps..

Hello there :
I would say the most common problem is a clogged fuel filter. Make sure you follow your manufacturers recommendations as to when you should change the fuel filter. This information should be in your owners manual. Symptoms include sputtering at high speeds or engine not starting at all. Always check the ignition system first, if that's ok then the next suspect is the fuel filter.
Next most common problem is the fuel pump failing. Most modern electric fuel pumps can be heard when you turn the key on. If you don't hear the pump running and your car will not start, it could be your fuel pump. The first thing a mechanic will check is the relay which sends power to the pump. If this is operating correctly then the pump will have to be replaced.
Last but not least is dirty injectors. While the fuel filter does a good job of filtering the fuel, it's not perfect. Over time deposits and tiny particles lodge themselves in the injectors. This can clog and injector and prevent it from delivering the fuel the engine needs. It can also cause an injector to stick open and send too much fuel into the engine. A regular addition of fuel system cleaner like STP Injector Cleaner, or Techtron fuel system cleaner can help keep your injectors clean. Most gas stations, department stores and all automotive parts stores will have a good cleaner available. Add it to your empty tank right before you fill up and it will clean as you drive. I recommend doing this every 3 months to keep your injectors performing like new. Mechanics also offer a cleaning service where they actually disconnect the fuel line and flush cleaner through the engine. This is only necessary when you let your injectors get to a point where they can not be cleaned by a store-bought product. Regular use of a good in-tank cleaner will keep you from having to pay for this service. Where do you buy your gas?
Believe it, or not, it can make a difference. Always buy from a well know national brand service station. Gas stations which are not affiliated with one brand of gas tend to get whatever is left at the end of the day from the delivery truck. One day them might get Texaco, and Exxon another. Also water mixed with gas will cause problems with your engine. The engine will not run right, plus the water will promote rust in the fuel system. I have experienced this when I purchased gas at some no-name gas stations. Your car will feel sluggish and sometimes refuse to run if there is enough water in the gas.
Octane rating tip !!!!
Putting super in the tank will not get you any more performance or gas mileage unless specifically recommended by your cars manufacturer. If your owners manual says put in 87 octane...... DO IT. You are throwing money out the window if you are filling up on Super or Premium and you only need Regular.
Hope this is very helpful for you '
Best regards Michael

If yours is the v6 2.5 the tps is adjustable and you can turn it up and down. On my mazda it acted like it was in the fuel system and i ended up replacing the distributor.

SOURCE: what is the hot-wire number
disconnect the sensor, use a volt meter (avil from radio shack for less than $6.00) and carefully probe the connector wires with the volt meter set to 200 DC volt scale, with the ignition key turned to run, u will find one wire with about 5.0 volts, that is the reference voltage generated by the computer, that is the hot wire as you call it.
