GM-GMC: knock sensor, knock sensor, new sensor

Question
engine light on plug in scanner says low voltage to bank 2 knock sensor just put in new sensor and wire pigtail what causes the low voltage to sensors

Answer
my truck currently has the same issue. the description you got from the code does not mean that theres low voltage to the sensor it just means that the sensor went out and needed to be replaced i am about to replace both of mine just in case.

no biggie.

it is not something that will continue to happen i have seen all the sensor codes and it seems to always say low voltage and i believe thats just sayin that the knock sensor went bad and needs replacing. i have had this happen on two of my vans and now my 05 gmc just gave me that code.
