Hello. The location of the knock sensor would be dependent on which model of engine your 4Runner is equipped with. Knock sensors are usually bolted directly to the engine block, as they are designed to monitor and detect engine knock in the vehicle’s cylinders. If your vehicle is equipped with the 3.4L V6 engine then the knock sensors are located in the valley of the engine, beneath the intake manifold. The knock sensor for bank 1 should be easily accessible, while bank 2 will require removal of the intake. If your 4Runner is equipped with the 2.6L I4 engine then the knock sensor is located on the block, beneath the intake plenum. If you are experiencing issues with the knock sensor also keep in mind that the wiring and connector can also commonly fail and set off codes or cause problems.
