So I've been having issues with my knock sensor for about the past year. I keep getting Low Circuit P0327. I've tried everything to fix it, multiple new sensors, rewired from sensor to the pcm, even put in a new pcm and no luck. Just for reference, my sensor is a single wire and grounds through the block. Last thing I have to try its running a tap through where it screws in. Anyone have any insight on what I could do? This is completly messing up my tune.
