Parts & Accessories Spare parts Peace, mercy, and blessings of God be upon you. I have an exhaust sensor link (oxygen sensor) available. It fits most types of cars, for example: (Tahoe - Suburban - Yukon - Yukon XL -) The function of the part is to hide the P0420 code, the oxygen sensor code, if the problem is not with the sensor itself. Quantity: 1 only Price: 80. We will not differ with the serious buyer, God willing.
