Keep your engine's air-fuel feedback accurate with the DENSO Auto Parts Oxygen Sensor 234-4368 — a heated, narrow-band, 4-wire direct-fit sensor that installs on a range of Acura and Honda models, including the 2001-2006 Acura MDX, 2005-2008 Acura RL, 2004-2006 Acura TL, 2003-2007 Honda Accord, 2005-2010 Honda Odyssey, 2003-2008 Honda Pilot, 2006-2008 Honda Ridgeline, and 2004-2005 Honda S2000.
- Laser-welded stainless housing: resists corrosion, while a PTFE filter blocks contaminants under harsh engine conditions.
- Dual-layer protection: shields the ceramic element to support fast, reliable response times.
- Aluminum oxide trap layer: DENSO's exclusive layer designed to protect the ceramic element from silicone and lead poisoning.
- 4-wire heated design: threaded mounting and a male connector, with a 0.708 in thread diameter and a 21.26 in wiring harness.
An oxygen sensor measures the oxygen content in the exhaust stream and signals the engine computer, which trims the air-fuel ratio; the heated element reaches operating temperature quickly for accurate readings soon after start-up. If a contaminated or failed sensor is the cause of a check-engine light, rough running, or poor fuel economy, this replaces it. This DENSO part is cataloged for upstream and downstream positions (including downstream front and downstream rear) depending on the application.
