1999 Chevrolet Silverado, 150K miles, trouble code “P0332”.
Did a search on ChevyTalk for “Knock Sensor”:
P0332 Knock Sensor Low Input Bank 2.
Knock sensors located under intake manifold.
Aprox. 5 or so hours to replace.

Took me about 7.5 hours:
1.5 hours to pull manifold.
1.5 hours to clean the mess out from under the manifold.
1.5 hours to explain to nosey neighbor what I was doing.
1.5 hours to buy parts.
1.5 hours to put back together.

Disconnect the throttle cable.
Lot of electrical plug in connectors to disconnect.
The injector electrical connectors do not need to be disconnected.
Remove the Vapor return line at front top of manifold.
Remove the aluminum throttle body (3 nuts holding it on).
10 manifold bolts , lift manifold then look for ground wire at back of manifold.
With manifold slightly lifted reach back and unbolt the ground wire.
Manifold is rolled to the driver side.
No way around buying the new wiring harness, the original is
Impossible to remove without breaking the sensor connectors.
Connectors at the Sensors are brittle and crack at the thought of being removed.

Knock sensors 2 @ $42 $84
GM knock sensor wiring harness $35
Intake gasket $35
