Sen Assembly-Oxygen

About this product

The Sen Assembly-Oxygen (#SU003-00428), a crucial electrical component within Toyota's Switch & Relay & Computer system, primarily functions to monitor the level of oxygen present in the exhaust gases. This part, also known as an oxygen sensor, provides vital data to the vehicle's engine control unit (ECU), which, in turn, adjusts the air-fuel mixture for optimal engine performance and fuel efficiency. Given its constant exposure to exhaust gases, this component can become clogged or fail over time, leading to inaccurate readings and potentially sub-optimal engine operation, affecting fuel economy and emission levels. Therefore, it's important to replace this part periodically with genuine Toyota parts for optimal compatibility and performance. All genuine Toyota parts are supported by Toyota's genuine parts warranty. By maintaining the correct air-fuel mixture, the Sen Assembly-Oxygen (#SU003-00428) plays a key role in ensuring that the vehicle operates efficiently and adheres to emission standards.
