B16A ECU codes...

:newbie:
:uhoh: Hey....first off i thought id let u know that im a chic....so if i sound dumb that would be why! :sorry: I just bought a 90 integra with a B16A swap and my check engine light is on. When i asked the kid i bought it off of if he knew why he had no clue and didnt even know you could get the codes off of the ECU. So me and my boyfriend checked it and its throwing codes 1 and 9. I know that 1 is the oxygen sensor and 9 is the cylinder position sensor. But now i dont know what i have to do. haha. do i replace these sensors? see if their connected? i cant really get a straight answer out of my boyfriend, and i dont even know where these sensors are located or where i would get new ones. id really appreciate it if someone helped me out here! :1zhelp: :sadwavey:

Your O2 sensor is conected to your headers, i have a b16 to, and to see it you have to remove the heat shield, and look behind the headers. If your check engine light it on you probably need to replace the sensor, the best plae to do that would be Honda. I'm not sure about the cylinder position sensor tho, sorry
