NTK Lambda Sensor UAA0001-MD021 (93225) Fits Mazda

This NTK Lambda Sensor UAA0001-MD021 (93225) Fits Mazda ensures the reduction of harmful emissions produced by the internal combustion engine, an important piece of technology.

An oxygen sensor, such as this lambda sensor, has the task of precisely measuring the air-fuel ratio present in exhaust gases. Moreover, the sensor informs the vehicle's ECU (Electronic Control Unit) in order to adjust the air-fuel ratio. This entire process helps firstly to effectively reduce harmful emissions. Secondly it optimises fuel consumption and ensures a long service life of the catalytic converter.
