I am just curious....My car has been getting knock spuratically for the past few months. I even upgraded to the delteq system and it still there. Sometimes its at WOT sometimes its at idle and crusing so I wanted to change out the Knock sensor to see if it helps but wanted to know What are the symptoms of a bad or Knock Sensor going bad?

I dont have any knock sensor code either.

Thx,
Claude

 

The code is a 43 for a bad sensor, best thing to do it test the voltage on the sensor. If thats out of whack then the sensor is bad.
