What PCM are you using??? F-body or B-body?? The F-body has 1 knock sensor!!! The B-body has 2!!! SO if your using a B-body in an F-body with only 1 knock sensor itll set your code!!! Im also pretty sure certain knock sensors are for certain years Maybe some others will add their input Also check the Knock Module inside the PCM if its gone itll set the same code!!! Hope this helps
