You may need to replace your knock sensors if you notice symptoms such as an illuminated check engine light, decreased engine performance, or unusual knocking or pinging sounds from the engine. Additionally, if your vehicle's onboard diagnostics system indicates an error code related to the knock sensors, it's a strong sign they may be malfunctioning. Regularly monitoring your vehicle's performance and addressing any unusual behavior can help prevent further engine issues.
They help control spark knock and the damage they can do.

On a 1999 Lexus RX300, the knock sensors are located on the engine block, typically underneath the intake manifold. You may need to remove the intake manifold to access them properly.

In order to change either or both of the Knock Sensors, you must first remove the wire connections. The sensors are physically located directly underneath the intake plenum. You will need a metal tool to remove the fuel lines also. Needle nose pliers may be needed to extract them. You will need to use some sort of sealant on the new sensors.
