Product Details

NTK Direct Fit Oxygen Sensor 24585 is part of the brand’s direct replacement line for import and domestic emission control applications. NTK uses ceramic manufacturing expertise and OE application knowledge to produce sensors that match factory-style installation and signal performance. This sensor is extensively tested during manufacturing to help meet or exceed OE specifications for fit and reliability.

Fits 2002-2004 Honda Odyssey, Upstream; Fits 2003-2004 Honda Pilot, Upstream; Fits 2001-2003 Acura CL, Upstream; Fits 2000-2003 Acura TL, Upstream; Fits 2001-2002 Acura MDX, Upstream. This part cross-references DENSO Auto Parts (e.g., 234-4368, 234-4727) for the same application.

Common Issues This Sensor Can Address

• Check engine light related to upstream oxygen sensor performance
• Incorrect air/fuel ratio feedback at Bank 1 Sensor 1
• Slow sensor response from a worn heated oxygen sensor
• Emission control faults tied to inaccurate exhaust oxygen readings
• Driveability concerns caused by degraded sensor output

Installation Notes and Tips

Confirm the vehicle’s engine layout, upstream location, and Bank 1 Sensor 1 position before installation. Match the threaded mounting style, 4-wire connector layout, and harness length to the original sensor on the vehicle. For Honda Odyssey, Honda Pilot, Acura CL, Acura TL, and Acura MDX applications, verify connector routing and exhaust placement before final tightening.
