A knock sensor (located on passenger side above oil pan rail, in the block) sends signals to an ESC module which then signals the ECM that knocking is being detected.

Best way to test is to watch the reading on a good engine capable scanner.

I hear no pinging, but then again, the water pump could be drounding it out.

It is a dark blue wire at the sensor. It'll be by itself and have a disconnect built in. The code sets if the voltage is outside the range of 1.5-3.5V. The only thing that I have come up with is to keep adding grounds.
