• Fits 2007-2010 Honda Odyssey, Upstream Front — Bank 2, sensor 1, Oxygen Sensor; Direct Fit 5-Wire A/F Sensor
• Fits 2007-2009 Acura MDX, Upstream Rear — Bank 1 Sensor 1 Oxygen Sensor; Direct Fit 5-Wire A/F Sensor
• Fits 2007-2009 Acura MDX, Upstream Front — Bank 2, sensor 1, Oxygen Sensor; Direct Fit 5-Wire A/F Sensor

What This Sensor Helps Address

• Check engine light concerns related to air/fuel ratio sensor performance
• Incorrect upstream oxygen sensor readings
• Rough idle or drivability issues tied to fuel mixture feedback
• Reduced fuel control accuracy from a worn sensor
• Service replacement needs on Honda Odyssey and Acura MDX upstream positions

Installation Notes and Tips

Confirm the connector, wire count, thread diameter, and upstream position before installation. This NTK 24346 sensor is a specific-fit replacement, so matching the exact bank and sensor location is important for proper operation on the Honda Odyssey and Acura MDX applications listed. Use the vehicle service information for torque and routing guidance, and verify the harness length provides proper reach without strain.
