Hey everybody sorry for posting this as a new post now, but this is very troubling and I would rather not take it to the garage and spend a fortune.

When I was up at Gettysburg being line security for the 150th, on the way home I got two check engine lights
P0332 - Knock Sensor 2 Circuit Low Input (bank 2)
P0101 Mass or Volume Air Flow Circuit Range/ Performance

I'm a about 99% sure the P0101 is a dirty Mass Air Flow Sensor, which I can clean no problem. The one that I am confused about is the P0332. Right after the codes, I cleaned the intake manifold and replaced both knock sensors with brand new ones. After clearing the codes and about 50 miles later the codes are back. Later I cleared the code, and disconnected the negative terminal for a few minutes but it's still there.

The truck is REALLY hurting in the low rpms for power, as it VERY sluggish when I try to pull out quickly. Could it be that I got "bad" new knock sensor or something more serious?

Could it be I need a new knock sensor sub-harness?? Just throwing out ideas.

I run Sunocco 93 so I know I'm running good gas. The truck doesn't seem knocking to me so what do you guys think?
Bad replacement sensor? Need new knock sensor sub harness? Something more serious?

Kyle, you need to check the reference voltage at the sensor. It should be around 5 volts with engine running (it may be there with key on and engine not running as well).

If there is no voltage, you may have a broken/dirty wiring connection.

Tomorrow I plan on replacing the knock sensor sub harness, will most likely check it then. Thank you
