How to disconnect, remove, and replace the Knock Sensor on Lexus RX350?

For four-cylinder models, the knock sensor is on the engine block's backside, requiring intake manifold removal. Disconnect the negative battery cable, remove the intake manifold, and disconnect the sensor's electrical connector. Remove the retaining nut and the sensor. During installation, angle the sensor's electrical terminal slightly below the horizontal. For V6 models, the knock sensors are between the cylinder heads, also requiring intake manifold removal.
