Direct-Fit Air/Fuel Ratio Sensor

NTK 24670 is a direct-fit air/fuel ratio sensor for select Toyota applications. It uses a heated, 4-wire design with a specific-fit configuration for accurate replacement of the original sensor.

  • Direct-fit replacement for select Toyota emission control applications
  • Heated sensor design for faster operating response
  • 4-wire configuration with a specific-fit layout
  • 18.000 mm thread diameter and 0.38 thread length
  • 16.5 wiring harness length for application-specific routing

Fitment and Application Details

Compatible with upstream Toyota Tacoma and Toyota Tundra applications from 2001-2004, plus select 2000 Tacoma and 2000 Tundra configurations. It also fits 1999-2000 Toyota 4Runner upstream applications, with California emissions and Bank 1 Sensor 1 notes where listed. NTK 24670 is built for air/fuel ratio control in Toyota Tacoma, Toyota Tundra, and Toyota 4Runner emission systems.

This part cross-references DENSO Auto Parts (e.g., 234-9002, 234-9003) for the same application.

What It Helps Address

  • Faulty oxygen sensor or air/fuel ratio sensor readings
  • Check engine light concerns related to mixture control
  • Slow sensor response during closed-loop operation
  • Emission system performance issues on upstream sensor circuits

Installation Notes and Quality

Install as a specific-fit replacement using the listed thread size, thread length, and harness length for the correct application. Mounting bracket is not included. NTK states that its oxygen sensors are extensively tested during manufacturing and are built to meet or exceed OE specifications.
