In order to perform these functions properly, the sensors must adhere to OE standards within incredibly close tolerances. The basic job of the sensor is to monitor the air fuel mixture under idle, moderate acceleration and cruise conditions.

Fixed a P0031 code
This fixed a P0031 code in my 2004 Subaru Impreza STI. Although the price of these sensors seems high for what they are. I doubt if the cost to manufacture this part is anywhere near what they retail for.
