hey guys not to long ago i was playing with the DR mod and as soon as i started driving the ecu threw a 0304 code. i reset the ecu to see if it would come back and it never did. Should i still worry about the Knock Sensor? also is there a way to test to see if it needs to be replaced?
Thanks

 

Read the FAQs (especially the "check engine" one) for answers. And if you run a self diagnosis on your ECU, I bet it will still spit 0304. Mine does!

 

fix that...replacing knock sensor is so awesome

 

The knock sensor won't trigger the CE light
