I have a 2018 GX460 with 100 K miles and have a fault code P033D #4. I'm in the process of removing the intake manifold to access the valley area to get to the sensors.
I have a few questions for the group. Due to the amount of disassembly to access the valley, should I?

I have a 2018 GX460 with 100 K miles and have a fault code P033D #4. I'm in the process of removing the intake manifold to access the valley area to get to the sensors.
I have a few questions for the group. Due to the amount of disassembly to access the valley, should I?
- Any tips on disconnecting the wire harness from the intake that's at the back of the engine.
- Replace all four knock sensors
- Replace the knock sensor harness
- Remove and reseal the valley plate even though I have no signs of coolant leaking
- Any other parts change recommendations as precautionary since I am doing this job
