Detailed Description

Autotecnica TY1318665 is an aftermarket oxygen sensor engineered for vehicles that rely on precise exhaust-gas feedback to manage air-fuel ratio and emissions performance. This heated sensor design helps the engine control system reach operating feedback more quickly, which is important for drivability and emissions monitoring on applications such as the Toyota Camry, Toyota RAV4, Toyota Sienna, Scion xB, Scion tC, and Lexus RX350/RX450h.

Built to OE-style specifications, this part is a direct replacement option for drivers and technicians servicing Toyota Camry oxygen sensor, Toyota RAV4 oxygen sensor, or Lexus RX350 oxygen sensor applications. The TY1318665 part number is also referenced by several aftermarket and OE-equivalent numbers, including DENSO 234-9041 and Delphi ES10934.
