NTK Direct Fit A/F Sensor for Nissan Altima
NTK Part Number 24854 is a direct fit heated air/fuel ratio sensor built for precise exhaust feedback on select 2011-2013 Nissan Altima applications. It is engineered for upstream placement and OE-equivalent fitment, making it a practical replacement for a failing sensor on Federal Emissions vehicles.
Key Features
- Direct Fit 4-wire air/fuel ratio sensor for specific applications
- Heated sensor design for faster operating temperature and stable signal output
- 14.8 in. wiring harness length for OE-style routing
- 18.0 mm thread diameter with 0.38 in. thread length
- Specific fit design for upstream installation
- NTK Part Number 24854
Product Details
NTK is known for oxygen and air/fuel ratio sensor manufacturing across import and domestic vehicle coverage, and this Direct Fit 4-Wire A/F Sensor reflects that OE-focused approach. NTK uses controlled ceramic technology and extensive manufacturing testing to support consistent sensor performance, fit, and signal accuracy. For drivers and technicians servicing a Nissan Altima, Part Number 24854 provides a direct replacement option for the upstream sensor position on 2011-2013 models with Federal Emissions and OE equivalent design requirements.
This part cross-references Bosch 18096 and DENSO Auto Parts 234-9107 for the same application.
Vehicle Fitment
- Fits 2011-2013 Nissan Altima, upstream. B1S1 Oxygen Sensor for Federal Emissions with OE Equivalent Design; Direct Fit 4-Wire A/F Sensor.
Common Replacement Reasons
- Check engine light related to air/fuel ratio sensor performance
- Rough idle or inconsistent fuel trim readings
- Reduced fuel economy caused by inaccurate exhaust feedback
- Slow sensor response during closed-loop operation
- Emission test failure tied to upstream sensor faults
Installation Notes
Confirm the upstream sensor location and Federal Emissions application before installation. Match the connector, thread size, and harness routing to the original sensor, and inspect the exhaust bung threads for damage before tightening. For Nissan Altima service, verify the vehicle year and engine/emissions configuration against the listed fitment before replacing Part Number 24854.
Quality Assurance
NTK manufactures oxygen and air/fuel ratio sensors with OE-specification testing to support reliable operation and consistent fit. As part of the NGK family of products, NTK focuses on sensor coverage and application-specific design for import and domestic vehicles.
