I didn't have a knock sensor plug in before but after i did the check engine went off. The weird thing is that my check engine comes on for the vss after i plug in my knock sensor and if i unplug my knock sensor the check engine comes on for that but it doesn't come on for the vss. I'm running a jdm b16a with a pr3 can anyone help me out with this. Btw my vtec doesn't even work anymore after i got it back from the shop.

 

i guess no knows what to do about this huh. i just found today that now its giving me both codes now. is it the ecu or just bad sensors, due to that i have a calbe speed sensor werid.
