The Additional Technical Information：
A critical component of today’s modern vehicle is the sensor measuring the exhaust gases. This sensor works with the vehicle Electronic Control Unit (ECU) to constantly maintain the operation efficiency of the engine. If the oxygen content in the exhaust gas is too high (a lean mixture) or too low (a rich mixture), the sensor is able to transmit this information back to the ECU, which then adjust the air to fuel ratio.
Not all vehicles have sensors with the same output characteristics and these sensors are not interchangeable. It is important to confirm sensor type before making the repair.
In vehicles equipped with a heated oxygen sensor, the output voltage changes in accordance with the oxygen concentration in the exhaust gas. The ECU uses this output voltage to determine whether the present air/fuel ratio is richer or leaner than the stoichiometric air/fuel ratio (14.7:1).
