See picture for location and where to disconnect. All they say is to remove air cleaner to remove it in our manual. Do not tighten over 20 NM or it will be instantly destroyed.

Do you think I will have to remove the manifold too. To take the sensor off the block?

Nope, You remove the air box off the front of the engine and the sensors are bolted to the block on each side.
