I got these codes when my check engine light came on. Does anyone know what:
9,3 : EVAP Canister vent control valve means?
3,4 : Knock Sensor
7,5 : EVAP Control System
I know that the knock sensor code came up because of the other two. But does anyone know what they are and how you clean/fix it without going to the stealership. Any help would be appreciated.
Oh, by the way, I've had these before and I just reset the light, but it came back on a few days ago. So just reseting it doesn't work.

 

knock sensor is bolted to the engine, gotaa replace that.

the other 2 are for smog devices. the evap can is where the gas tank is
