Just got my car back for the abs system and now I am getting the p0327 code bank 1 knock sensor. My question is I put 87 octane in, only a couple gallons. Could that be causing it? I just filled up with premium and added fuel cleaner. Reset the code 3 times today and it came back all three times? Or do I just need to drive it for a while and hope for it to reset itself? Or do I need a new sensor?

 

Forgot to add 04 3.8 SC

 

take a look at this video, it might help.

 

Well i have figured out the problem to my car. Turns out the dealership I had it at for the abs repair messed with my harness to repair the abs connector and pulled the wire out of the knock sensor connector and never bothered to repair it. Also found a bolt missing out of the trans housing where my cold air intake bracket bolted, which coincidentally is also where they spliced in to the abs system. Great job on their part, I am livid.
