Detailed Description

NTK 25572 is an upstream oxygen sensor for vehicles that use a threaded, non-heated sensor configuration. It is listed for a wide range of Nissan models, including 1989-1995 Nissan 240SX, 1993-1995 Nissan Altima, 1987-1994 Nissan D21, and 1989-1993 Nissan Sentra, along with select Jaguar XJ6 and Vanden Plas applications. If you need a direct fit oxygen sensor for Nissan 200SX, Sentra, or Altima applications, this part number is built around the original equipment style used on those vehicles.

NTK is known for oxygen sensor manufacturing and OE application coverage, with production methods focused on ceramic control and manufacturing consistency. This sensor is tested during production to help meet OE specifications for fit and performance on the listed applications. This part cross-references Bosch 12046 for the same application.

Common Issues This Sensor Can Address

• Faulty upstream oxygen sensor readings
• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback at Bank 1 Sensor 1
• Rough idle or drivability concerns tied to sensor signal loss
• Emissions test failure caused by a worn oxygen sensor

Installation Notes and Tips

Verify the vehicle year, make, model, emissions package, and sensor position before ordering. This NTK 25572 oxygen sensor is listed for upstream Bank 1 Sensor 1 locations on the confirmed applications, including Federal Emissions and California Emissions variants where noted. Match the threaded mounting style, harness length, and connector routing to the original sensor before installation.

For best results, inspect the exhaust threads and wiring path before replacing the sensor. Confirm the application details for Nissan 200SX, Nissan Sentra, Nissan Altima, and other listed models to ensure the correct upstream sensor is selected.

Quality Assurance

NTK manufactures oxygen sensors with OE-focused engineering and extensive production testing to support reliable operation on the listed applications. The brand’s OE application expertise and controlled ceramic manufacturing process are part of its quality approach for direct fit emission control sensors.
