Fault Code KnockSensor2 520197

We ran the boat at full throttle to try get back to the covered slip to beat the rain yesterday. An alarm sounded. It had a fault code: KnockSensor2 SPN 520197 CM 0

Voltage Short or below normal RNG FMI 4 OC 1

I haven’t looked yet. Due to the code description, I assume there is a knock sensor on each side of the block. If so, which one is knock sensor 2?  How do I troubleshoot to determine if it is a bad sensor or what other problem it may have?

On my 03 there is only a knock sensor on the starboard side. So would #2 be port side?  K/S codes normally don't come in till you get above 3000-3500 rpm.
