About the Sienna

The Sienna first made its debut in 1998. Since then, there have been four generations to hit the markets. The latest of these was released in 2020. The model has also been sold as the Granvia, which was released in China in 2022.

It is sold mostly in the North American market, as well as the East Asian market. Interestingly, it became the only all-wheel drive minivan in the United States between 2006 and 2021.

The main rivals for the model include the Honda Odyssey and Kia Carnival. In America, it also goes up against the Dodge Caravan and Chrysler Pacifica.

One of the most common issues that the Sienna faces is P0430, which indicates that the catalytic converter in the second bank of the exhaust system is not performing properly. This means that only certain models, like those with V6 engines, can be susceptible to this issue.

The most likely causes of this problem are exhaust leaks upstream of the converter or a failing catalytic converter.

Another fairly common code is P0015. This code indicates that the exhaust camshaft is too far behind in terms of timing.

Owners have reported that one of the main causes for this issue is simply neglecting proper maintenance. Old, contaminated oil can result in improper variable valve timing.

While Toyotas are known for their reliability, they are somewhat prone to camshaft timing issues. As a testament to how easily this can be overlooked, another common code for the Sienna is P0012, which is the same issue but for the intake camshaft.

Again, old fuel can be the primary cause of this problem. Another fairly common issue is a worn timing chain.
