How do you replace the knock sensor on 2003 through 2009 Toyota 4Runner?

For V6 models, the knock sensors are located on top of the engine block, under the intake manifold, and accessing them is extremely difficult as it requires removing the cylinder heads; therefore, it is advisable to replace both sensors even if only one is defective. Begin by draining the engine coolant, then remove the cylinder heads, followed by the heater coolant inlet hose and the coolant outlet pipe. Disconnect the electrical connectors from the knock sensors, carefully noting their orientation before removing the sensor retaining bolts and the sensors themselves. Proper orientation is critical to avoid clearance issues during the installation of the cylinder heads and intake manifold, so ensure each sensor is positioned exactly as it was before removal, then tighten the retaining bolts to the specified torque. The remainder of the installation follows the reverse order of removal, and finally, refill the engine cooling system. For V8 models, the knock sensors are also located on top of the engine block, under the intake manifold, in front of the starter motor, and for 2003 and later models, the air injection pump must be removed to access them. Start by removing the upper and lower intake manifolds as a single assembly without separating them. Disconnect the knock sensor electrical connector; for 2003 and 2004 models, the sensors are screw-in types, while for 2005 and later models, they are bolted to the engine. Unscrew the knock sensor with a deep socket for the earlier models or remove the retaining bolts for the later models. Installation is the reverse of removal, ensuring to tighten the sensors or retaining bolts to the specified torque. Finally, refill the engine cooling system.
