Have code p0325 and p0330. Having trouble locating the knock sensors. Was wondering if its unusual that both sensors go bad at the same time. Have just replaced the #3 coil pack and thought that would clear the code. Could use some advice

Here is a diagram for the knock sensors. A common connection to both is C1019.

so, you have a misfire? the reason for the coil pack replacement?
The Knock Sensors run on separate circuits however they share the same harness feed and (1) connector C1019 - which also has the injector wiring

Check this connector for security and moisture corrosion

Thks. After looking at everything i'm thinking this one is above my skill level. All this started because mice chewed through several wires going to coil packs. Once i repaired the wires one coil pack showed with error code so replaced it. Dont see where the wires to the knock sensors have been chewed on but dont have a clear line of sight for everything. And i just have a hand held code reader. Seems to be running ok. But probably better to get it checked by a pro. Thks again

If no visible damage, then you will need a circuit test (tone test)
Disconnect the PCM Connector and both Knock Sensors
And at the Knock Sensor connector - apply power to the wire tone generator to (one wire) or jumper to both and then follow the harness with the probe and listen for the tone to drop out or lower in frequency. This will be the point of damage
I use mine for the hard to find - breaks in the wire harness it has more than paid for itself

I would pay closer attention to the areas where you had to repair the wiring as the Knock Sensor wires are - twisted pair and any damage to the wire or nearby wire may introduce faults on the circuit.
