How to check and replace Knock Sensor on Toyota Sienna?

The knock control system is designed to reduce spark knock during heavy detonation, allowing the engine to utilize optimal spark advance for improved driveability. The knock sensor detects abnormal engine vibrations and produces a voltage output that increases with the severity of the knock, which is monitored by the PCM to retard ignition timing until detonation ceases. The models in question use two knock sensors located under the intake manifold. To check a knock sensor, disconnect the electrical connector and verify that there is no continuity between the sensor terminal and the body of the sensor using an ohmmeter; continuity should not exist, and if it does, the sensor should be replaced. For replacement, first disconnect the cable from the negative terminal of the battery, then drain the cooling system, remove the lower intake manifold, disconnect the electrical connector, and remove the knock sensor. If reusing the old sensor, coat the threads with thread sealant, as new sensors come pre-coated. Install the knock sensor securely, approximately 30 ft-lbs, avoiding overtightening to prevent damage. Finally, reconnect the electrical connector, reinstall the remaining components, refill the cooling system, and check for leaks.
