you need to go to an advance auto parts store and get a Haynes repair manual for it they have all the info in there you will ever need for that vehicle,its made specially for the Geo so it will help you a lot ,good luck i hope this help,s.What sensors activate the ';service soon'; indication in a 1996 GEO, oil, filter air-filter plugs new, stil on.
first one that comes to mind is the O2 sensor, you did not say if the car is running badly the O2 sensor is usually the first to go a good place to go is your local auto parts store i like autozone as they can bring out a diagnostic tool to tell you what is wrong for free and they have the parts on hand to fix it, as for the geo book try asking your local GM dealer if they are still available if not try hemmings motor news found at good book stores just ask they will direct you to it even wal-mart sells them, if the light came on after you changed the air filter check to see if you got the filter housing sealed right if not it will let in to much air and throw off the sensors and give you a light. oops almost forgot at the auto parts store they may have a repair manual for your Geo, my bro. had a Geo and he ran the snot out of it he really liked it. Good luck
try holding in the trip meter reset button while turning the key to the ignition ';on'; position hold it there for about ten seconds and you will probably hear a beep or the indicator will go off it works with most cars





hope this helps dude
Its a 96..... so its obd2


Go get the codes scanned (either at autozone, or advance auto) to determine the exact problem before you go throwing parts at it...


After fixed.. take the battery cable off to reset the computer.
the service soon light comes on whenever there is a fault in a sensor or system that affects emissions. from vacuum leaks evap system cats fuel system. your best bet is to go get your car scanned to find out what code it is and follow up from there. even if you get lucky and replace the correct sensor the light will stay on till the code is erased or after a certain number of drive cycles after it no longer detects the fault.
I know on a lot of the vehicles you have to turn the ignition to where you only get battery power. Then press the gas pedal 3 times. turn the ignition off and start the car. I know it sounds ridiculous but I have to do that to my car every time that thing comes on. Then it will come up again when you need to change the oil. It will probably say in the owners manual if you have it available
