ITEM NAME:Car CEL Fix Check Engine Light Eliminator Adapters - Oxygen O2 Sensor M18X1 G9X2 Explain: 1. Made of high-quality materials, durable and practical. 2. Don't expand only when the extension doesn't work. This is the built-in real Mini catalyst. 3. When the catalyst is removed, the rear oxygen sensor will display higher temperature and higher flow of unburned fuel. 4. As a result, this throws a check engine light (unit, SES, DTC) with error codes typically p0420 (catalyst system efficiency below threshold library 1) and / or p0430 p0420 catalyst system efficiency below threshold library 2). Off road only.
