so i found the button to be able to flash the codes manually. it is right behind the plug where the code reader would plug in. i had a code 333 in the bank. i gonna swap out the ICP sensor and harness this week. supposedly you can also clear the codes manually as well. hold button down, turn key on, pump gas 3 times and let go of button. havent tried that yet, gonna swap sensor out first then clear them. guess i just need to find a list of all the codes.
