I just replaced my AFM with a used one because I was getting code 1224-Intake Air Temp Sensor. The check engine light went out as soon as I started it up again but when I check for codes with the stomp method, I still get code 1224. Do I have to reset the computer to get the code to go away? I tried unplugging all of the injection control fuses for a while to no avail. I figure the new AFM has a working IAT because the light went out but what's with this code?
