This is the factory service and repair manual for the 2020 Toyota Sienna, written to the van Toyota actually built that year, from the 3.5L V6 (2GR-FKS) under the hood to the trim on your door jamb, so the figures you work to are the ones Toyota published for this model year rather than values carried over from an adjacent one.

Known issues on the 2020 Sienna. Two recalls are on federal record for this model year. The first is a steering recall covering Sienna vans modified by Braun Corporation, where the steering shaft extensions may have been improperly manufactured; if an extension fractures completely, it can cause a loss of steering. The second covers the gasoline fuel pump: if the pump fails, the engine can stall while driving, increasing the risk of a crash. Owners have logged 46 complaints for the year, and Toyota has issued 135 technical service bulletins.
Whether you are tracing a stall back to the fuel pump, inspecting the steering, or working through a scheduled service item, you are following Toyota's own procedure for the 2020 Sienna rather than a generic one.
