Direct-Fit Air/Fuel Ratio Sensor for Toyota

NTK Part Number 24669 is a direct-fit heated air/fuel ratio sensor built for specific Toyota applications. It is engineered for OE-style fit, form, and function, with a 4-wire design and a specific-fit harness for straightforward replacement on select Tacoma, Tundra, and 4Runner models.

Key Features

  • Direct Fit 4-Wire A/F Sensor for specific Toyota applications
  • Heated sensor design for faster operating temperature
  • Specific-fit wiring harness with 12.3 in. length
  • 18 mm thread diameter with 0.38 in. thread length
  • OE-style replacement for upstream Bank 1 Sensor 1 and related upstream positions
  • NTK Part Number 24669

Product Details

NTK is known for oxygen and air/fuel ratio sensor manufacturing across import and domestic applications, and this sensor reflects that OE-focused approach. The 24669 uses ceramic-based sensor technology and is manufactured to meet or exceed OE specifications for fit and performance. For drivers servicing a Toyota Tacoma, Toyota Tundra, or Toyota 4Runner, this direct-fit sensor supports accurate air/fuel monitoring in upstream locations, including Bank 1 Sensor 1 applications and select California emissions configurations.

This part cross-references DENSO Auto Parts (e.g., 234-9001, 234-9002) for the same application.

Installation Notes

Confirm the upstream sensor position, bank designation, and emissions configuration before ordering. This NTK 24669 sensor uses a 4-wire heated design and a specific-fit harness, so the connector and routing should match the original sensor layout on the vehicle. Verify thread diameter and thread length against the OE unit during replacement.

Quality Assurance

NTK manufactures oxygen sensors with OE application coverage and extensive production testing to support consistent quality and reliability. As part of the NGK family of products, NTK focuses on sensor technology for import and domestic vehicles, including Toyota Tacoma, Toyota Tundra, and Toyota 4Runner applications.
