NTK Direct Fit Air/Fuel Ratio Sensor
NTK 24660 is a direct-fit heated air/fuel ratio sensor for specific Honda applications. It is built for upstream Bank 1 Sensor 1 placement and uses a 4-wire configuration with OE-style fitment for accurate replacement service.
As part of NTK’s Direct Fit 4-Wire A/F Sensor line, this sensor focuses on correct connector fit, proper thread dimensions, and application-specific coverage for import vehicles such as the Honda Insight and Honda Accord.
Key Features
- Direct-fit heated air/fuel ratio sensor for upstream use
- Specific fit design for OE-style replacement
- 4-wire configuration for the listed applications
- 18.000 mm thread diameter with 0.38 thread length
- 13.3 wiring harness length
- No mounting bracket included
Application Details
Fits 2001-2006 Honda Insight, upstream. Fits 2001-2002 Honda Accord, upstream. Fits 2000 Honda Accord, upstream. These applications reference Bank 1 Sensor 1 placement for air/fuel ratio service, including the 2000 Honda Accord with SULEV emissions standard and OE-equivalent design.
NTK is known for OE sensor manufacturing and ceramic technology control from raw material through finished sensor production. That manufacturing approach supports consistent fit, form, and function for replacement work on Honda Insight and Honda Accord models. Part number 24660 also cross-references DENSO Auto Parts 234-9013 for the same application.
What This Sensor Helps Address
- Check engine light related to upstream air/fuel ratio sensor faults
- Incorrect fuel trim readings from a worn sensor
- Slow sensor response affecting drivability
- Emissions test failures tied to sensor performance
- OE connector or fitment mismatch on replacement service
Installation Notes
Install in the upstream Bank 1 Sensor 1 position only for the listed vehicles. Verify thread diameter, harness length, and connector style before installation. Use proper exhaust sensor service practices to avoid damaging the sensing element or wiring during removal and installation.
Quality Assurance
NTK manufactures oxygen and air/fuel ratio sensors with extensive testing during production to help ensure quality and reliability that meet or exceed OE specifications. Part number 24660 is backed by NTK’s OE-focused sensor engineering for import and domestic applications.
