Ok i put in a vafc and im geting a check engine light at first i didnt put the vtm wire but i did it and it still comes on i check the and im getting a code 23 and 13 what should i do and what do these codes mean.

 

Code 23 is the knock sensor. Check it or it's wiring.

Code 13 is the barometric pressure sensor. I think(??) it's built into the ECM...

 

did you reset the ecu after correcting the vtm?
