NTK 24634 Oxygen Sensor - Downstream Rear or Downstream Right

Direct Fit Oxygen Sensor for Nissan and INFINITI

NTK 24634 is a direct fit heated oxygen sensor built for specific downstream applications on select Nissan and INFINITI vehicles. It uses a threaded mounting design, 4-wire configuration, and a 39.5-inch wiring harness length to match the original sensor layout for the listed vehicles.

Compatible With 2002-2004 INFINITI I35, downstream right, and 2002-2003 Nissan Maxima, downstream rear. If you are replacing a downstream oxygen sensor on an INFINITI I35 or Nissan Maxima, NTK 24634 provides an OE-style fitment match for the original application.

Key Features

• Direct fit oxygen sensor for specific downstream applications
• Heated sensor design for faster operating response
• 4-wire configuration
• Threaded mounting type with 18 mm thread diameter
• 39.5-inch wiring harness length
• Specific fit for listed Nissan and INFINITI models

Product Details

NTK Direct Fit Oxygen Sensor 24634 is part of NTK’s OE-focused sensor line, developed with ceramic manufacturing expertise and application coverage for import and domestic vehicles. NTK supplies oxygen sensors to original equipment programs and tests sensors during manufacturing to help ensure the finished part meets OE-level fit, form, and function expectations. This part cross-references Bosch 15225 for the same application.

For 2002-2004 INFINITI I35 downstream right and 2002-2003 Nissan Maxima downstream rear applications, this sensor is built to match the original mounting style and electrical layout. The direct fit design supports straightforward replacement when the downstream sensor has aged, failed, or triggered an emissions-related fault.

Common Issues This Sensor Can Address

• Check engine light related to downstream oxygen sensor performance
• Fault codes tied to oxygen sensor response or heater circuit operation
• Incorrect exhaust feedback readings after sensor aging or contamination
• Emissions test failures caused by a failing downstream sensor
• Rougher fuel control behavior when the sensor signal is no longer reliable

Installation Notes

Verify the vehicle position before installation: 2002-2004 INFINITI I35, downstream right, or 2002-2003 Nissan Maxima, downstream rear. Confirm the connector routing, harness length, and threaded mounting location match the original sensor before removal. Use proper oxygen sensor service tools and follow the vehicle service procedure for safe removal and installation.

Quality Assurance

NTK manufactures oxygen sensors with controlled ceramic technology and extensive production testing to support OE-level reliability and application accuracy. The NTK 24634 is engineered as a direct fit replacement for the listed Nissan and INFINITI applications.
