There are 2 sensors. One located within the engine compartment mounted on the exhaust pipes next to the engine block. The other is located next to the catalytic converter. As far as the code is concerned, consider taking out the sensor, clean it and reinstall it. Erase the code. Run engine for a couple of days. If the code comes back you should then replace the old sensor with a new one.

A Toyota Sienna engine can last between 200,000 to 300,000 miles with proper maintenance, including regular oil changes and timely repairs. Many owners report their Sienna engines reaching these high mileages, thanks to Toyota's reputation for reliability. Factors such as driving habits, maintenance practices, and environmental conditions can also influence engine longevity. Regular check-ups and addressing issues promptly can help extend the life of the engine.
The knock Sensor in a 1989-1992 Toyota cressida is located under the intake manifold, closer and under the cold start injecter. Behind the alternater. i had to use a small mirror to see it, or you can put your hand under and search for it.
