NTK 24232 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor for Mazda 3 and Mazda 5

NTK 24232 is a direct fit heated oxygen sensor built for specific downstream applications on select Mazda models. It is engineered for accurate exhaust monitoring, OE-style fitment, and reliable signal performance in 2004-2005 Mazda 3 and 2006-2007 Mazda 5 applications.

Key Features

• Direct fit, specific application oxygen sensor
• Heated sensor design for faster operating temperature
• 4-wire configuration with 31.0000 wiring harness length
• 18.000 thread diameter with threaded mounting type
• Downstream B1S2 placement for listed Mazda applications
• Built by NTK, the Sensor Specialist and original equipment oxygen sensor manufacturer

Product Details

NTK Direct Fit Oxygen Sensor 24232 is part of the NTK oxygen sensor line, which focuses on OE application coverage and precise sensor construction. NTK controls the ceramic element from raw material through finished product, supporting consistent sensor response and fit. This downstream oxygen sensor is listed for 2004-2005 Mazda 3 and 2006-2007 Mazda 5 models, including the 2004-2005 Mazda 3 Federal Emissions application with OE MFR: NTK. This part cross-references Bosch 15922 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect oxygen sensor signal readings in the exhaust system
• Emissions test failures tied to a worn or slow-responding sensor
• Fuel control issues caused by degraded exhaust feedback
• Replacement needs for a damaged or aging Mazda 3 or Mazda 5 downstream sensor

Installation Notes and Tips

Verify the connector, harness length, thread diameter, and downstream B1S2 location before installation. This is a specific-fit sensor for listed Mazda 3 and Mazda 5 applications, so match the vehicle year, engine/emissions configuration, and sensor position to the catalog listing before replacing the part. Use proper exhaust sensor removal procedures to avoid damaging the threads or wiring.

Quality Assurance

NTK manufactures oxygen sensors to meet or exceed OE specifications and tests them during production for quality and reliability. As the original equipment oxygen sensor supplier for many applications, NTK supports import and domestic coverage with OE-style fit, form, and function.
