The Toyota Sienna is a capable minivan targeted at families looking for a reliable, nimble, and capacious vehicle. It has a comfortable and well-trimmed interior, generous cargo area, and good performance. The vehicle was designed for intense daily use; for this reason, the emissions should be taken under strict monitoring, not only to pass the control tests but also keep the environment cleaner and safer. Oxygen sensors are among the most crucial components in the emission control system, as they send the data about the burnt gases to the ECU, which adjusts the fuel-air ratio accordingly.
This scheme relies on the difference of the oxygen content between the exhaust gases and atmosphere, and the sensors generate low-voltage impulses depending on oxygen quantity. These impulses are transmitted to the ECU at a certain frequency. The top shape of sensors is paramount for these signals to be precise, but over time, their sensitive elements wear out and get covered with soot and other pollutants, which affects the fuel-air mixture. We sell a large amount of top-notch Toyota Sienna oxygen sensors and components including connectors, extensions, bungs, and bung plugs. Made by renowned companies, our parts are reliable, durable, and affordably priced.
