Hi All! I am looking for the location of the anti-knock sensor on a 1992 Buick Regal custom. Can anyone help me please?

right in front. between cyl 2 and 4 (i believe).


but do you have a code for this, cuz those are extremely rare to fail.

code 43 is the one that keeps showing up

if you measure the resistance between the the ks pin and the eng block, you should get a reading between 3.3Kohms, and 4.5Kohms.
