i have a 99 civic coupe with a 98 GSR swap in it i have a CEL on i replaced the sensors that need to be replaced but the code for the primary heated o2 sensor sensor 1 is still poping up and the code for the IACV valve and im running a 2000 SI B16 ECU just wondering if there is anything i can do because in trying to get an inspection sticker

 

For the o2 sensor you need to make sure that there is voltage for the heater circuit going to the sensor. Start at the fuse.

Same for the iacv. Check to make sure it gets voltage at the plug. THen check to make sure there is ground.

 

thanks i will try that
