1 and 2 are o2 sensors how do i fix 17 is vss but i still hit vtec how do i fix and 23 is knock sensor how do i fix any help would be super nice im scared to drive it will it hurt any thing

 

17 and 23 wont hurt anything unless your motor is pinging. 17 is in your dash. gauge cluster spedomiter. if u take out the gauge cluster directly below the speed cable are 2 screws. thats the VSS. so theres a open between there and the ecu. 23 is knock sensor. i'm assuming your running a pw0 or pr3. knock is not nessary and u could ground the wire for it but as i'm oem freaky, i'd put one in.

 

code 17: is your speedo even working? (cable installed back into place, speed sensor hooked up)?

Code 23: Is your knock sensor wired up? Pin is B19 for knock on ECU.

 

thanks man
