2004 Sienna @ 260K KM's throwing P0328 code. I haven't seen anything specific for this vehicle. This has me stumped, and I'm not confident replacing the knock sensor will solve problem.

P0328 Knock Sensor Circuit High Input
A P0328 code is a generic DTC, thus it applies to all makes of vehicles, and refers to a high output voltage of the knock sensor. In many cases, this means the voltage is above 4.5V but that specific value depends on the specific make and model of vehicle. This code refers to the sensor on bank #1.
