Hey guys I am lost on what needs to be done next. I have both knock sensors detecting low voltage and can't seem to figure out why. I have replaced the front sensor with a working one (didn't fix it) and then I replaced the WHOLE engine wiring harness thinking that maybe the wires going to the sensors were bad no luck either. I also tried taping on the block to simulate knock on the motor and couldn't register anything on my scan tool
So my questions are
If I only replaced one sensor (front bank 1) would both still show as bad? (do they need to be replaced in pairs?)
What else could the problem be if its not the knock sensors failing or the wiring?
Is the PCM bad?
Here is a list of all of whats done to the car
9:5:1 Compression L67 Bored .20 over
VS Cam
3.4 Pulley
PEM
3" Full Exhaust
ZZP stage 1 TB
3.29 gears
I run a 10.9 AFR at WOT and about 11-12lbs of boost
Any help would be appreciated!!
