Product Details

Denso OE Style sensors are built and tested to OE standards, with precision manufacturing for first-time fit and consistent replacement performance. This Denso 234-4233 oxygen sensor uses an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting reliable engine management and long service life. It is a direct-fit oxygen sensor for 2003-2008 Toyota Corolla downstream, 2003-2008 Toyota Matrix downstream, 2003-2008 Pontiac Vibe downstream, plus select upstream applications on 2003 Toyota Matrix, 2003 Pontiac Vibe, and 2004 Toyota Matrix through 05/03.

This part cross-references Bosch 15290 or NTK 21547 for the same application.
