Hello everybody. I got the code P0325. It said it might be the knock sensor. I reset the code and it came back on after the car was warm. What could it be? Do i need to change the knock sensors or is it something else? Any help please.

 

Check the connection to make sure it's proper.
If it's an aftermarket type they usually don't last very long. On another brand vehicle I kept getting the code even after installing an oem one. I used a two wrap layer of teflon tape before reinstalling yet another one and never got another code.
I read somewhere that twisting it into the engine without a bit of thread tape allows vibrations to break it where using teflon tape apparently stops the thing from vibrating as much. I dunno if that's true or not but no more knock sensor codes after that.

 

Thanks ill try that
