Detailed Description

NTK 24447 is a downstream oxygen sensor for the 2008-2010 Mazda 5, B1S2 position. Built as a specific-fit replacement, it is intended to match the original sensor’s mounting, wiring, and signal requirements so the vehicle’s emission control system can monitor exhaust conditions accurately. The heated design helps the sensor reach operating temperature efficiently, supporting stable feedback once installed.

NTK develops oxygen sensors with controlled ceramic technology and extensive manufacturing testing to meet OE-level specifications. This part cross-references DENSO Auto Parts 234-4118 for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor performance
• Fault codes tied to oxygen sensor response or signal output
• Reduced emissions monitoring accuracy
• Rough or inconsistent fuel control caused by a failing sensor
• Replacement needs for a worn Mazda 5 downstream sensor

Installation Notes and Tips

Confirm the downstream B1S2 location before ordering. Match the 4-wire connector, threaded mounting style, and harness length to the original sensor on the 2008-2010 Mazda 5. Inspect the exhaust bung and wiring route before installation to ensure the replacement seats correctly and the harness is routed away from heat sources.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer, and this Direct Fit Oxygen Sensor line is manufactured and tested to meet or exceed OE specifications for fit and performance.
