How you know

A check engine light with a fuel trim or catalyst efficiency code. On a full-size car, trim and package content split these part numbers in ways a diagram will not show.

Buying OEM, briefly

• Factory warranty. Genuine oxygen sensors carry GM coverage aftermarket cannot match.
• Dealer parts, not dealer prices. Compare our oxygen sensors pricing against a counter quote.
• Genuine GM only. Every oxygen sensors listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the oxygen sensors before the box leaves.
• Central shipping origin. Dallas keeps oxygen sensors transit times short nationwide.

Confirming fitment

Factory parts are built to the tolerances the vehicle was engineered around, not copied from a worn sample. A photo is rarely enough to order from. The VIN takes seconds and removes the guesswork. Freight is quoted at what it actually costs, not inflated to subsidize a headline discount.
