NTK 24313 Air / Fuel Ratio Sensor - Upstream Left or Upstream Right

Direct Fit Air/Fuel Ratio Sensor

NTK 24313 is a direct fit air/fuel ratio sensor built for specific applications that require a heated 5-wire design. It is engineered for accurate exhaust feedback and OE-style fitment on select Saturn and Cadillac models.

Key Features

• Direct fit replacement for specific air/fuel ratio sensor applications
• Heated sensor design for faster operating response
• 5-wire configuration with 18.000 mm thread diameter
• 22.3 in. wiring harness length for application-specific routing
• NTK 24313 is manufactured to meet or exceed OE specifications

Detailed Description

NTK 24313 is part of NTK’s Direct Fit 5-Wire A/F Sensor line, which focuses on application-specific replacement sensors with OE-style form and function. NTK uses ceramic sensor technology and extensive manufacturing tests to support consistent performance and reliability. This part number is used on select Saturn L300, Saturn LW300, Saturn LS2, Saturn LW2, and Cadillac Catera applications, including upstream right and upstream left positions where specified by the vehicle fitment.

This part cross-references Bosch (e.g., 16065, 16066) for the same application.

What It Is Used For

• Replacing a worn or slow-responding air/fuel ratio sensor
• Restoring accurate exhaust mixture feedback to the engine control system
• Addressing sensor-related fault codes tied to mixture monitoring
• Correcting drivability issues caused by inaccurate oxygen sensor readings
• Supporting proper emissions system operation on compatible vehicles

Installation Notes and Tips

Verify the connector, wire count, thread size, and harness length before installation. This NTK 24313 sensor is a specific-fit part, so match the vehicle position and application notes exactly to the original sensor location. The mounting bracket is not included.
