(This answer has nothing to do with reseting the Theft System) The best way to go is to get a OBD 2 code reader/scanner. They are cheap (50-60 bucks) compaired to buying lots of parts you dont need. It will give you an angle of attack while leaving what the computer should know, intact. In other words, it wont run rough while it relearns everything and possibily setting off false codes. The only other way is to pull the ECM fuse that is under the hood for a minute or so.(i belive it is a 10 amp fuse) but you will erase not only the codes but the ROM (Read Only Memory) as well and will have to relearn, and you STILL wont know WHY the Check Engine Light came on. You can also disconnect the battery for a few mins. but you will be in that same boat as just pulling that fuse...So if you want to fix it yourself,get a code scanner,if you shop around you will see that the cost is way better than the aggravation of spending money on parts and still not fixing your car. Many times the scanner lead me to a bad connection at a plug-in on the sensor and had to buy nothing else,just unplug and plugin, problem solved,and they work on many different vehicles. And trust me...you WILL need it again.
Disconnect the battery for an hour, or so.
