2022 Toyota Avalon Service and Repair Manual
The 2022 Toyota Avalon was sold with two very different powertrains, and the service data splits along that line: the three Hybrid trims run the 2.5L four (A25A-FXS) working with the electric drive, while the other three run the 3.5L V6 (2GR-FKS). This is Toyota's own service and repair information written against the 2022 model year, so the figures you work to are the ones set for this build rather than a value carried over from an adjacent year.

Known issues on the 2022 Avalon. No recalls are on federal record for this model year. Owners have filed 10 complaints against it, and Toyota has issued 105 technical service bulletins for it.
That split matters once the hood is up. A hybrid Avalon carries a high-voltage system that has to be isolated before much of the underhood work, while the V6 cars follow conventional Toyota practice for the same jobs. Working to the specification for the engine actually in the car is what keeps a torque value or a diagnostic step from being wrong for your Avalon.
