NTK 24385 Air / Fuel Ratio Sensor - Upstream Front or Upstream Rear

NTK Direct Fit Air/Fuel Ratio Sensor

NTK Part Number 24385 is a direct fit heated air/fuel ratio sensor built for specific Honda and Acura applications. It is engineered for upstream placement and uses a 5-wire design to support accurate exhaust feedback for fuel control and emissions monitoring.

Key Features

• Direct fit replacement air/fuel ratio sensor for specific applications
• Heated sensor design for faster operating temperature
• 5-wire configuration for OE-style signal performance
• 18 mm thread diameter with 0.38 thread length
• 10.3 wiring harness length for application-specific routing
• Specific fitment for upstream rear and upstream front positions
• NTK Part Number 24385 for easy cross-reference

Product Details

NTK Direct Fit 5-Wire A/F Sensor 24385 is part of NTK’s direct replacement sensor line, built for import and domestic coverage with OE application focus. NTK is a major original equipment oxygen sensor supplier, and this sensor reflects that background with a specific-fit design, heated operation, and manufacturing controls aimed at consistent signal output and reliable installation fit. It is a strong match for drivers searching for a Honda Accord upstream oxygen sensor replacement, an Acura TL air/fuel ratio sensor, or an Acura MDX upstream sensor by part number 24385.

This part cross-references Bosch 18083 and DENSO Auto Parts 234-5098 for the same application.

Installation Notes

Confirm the sensor position before ordering, since this part is listed for both upstream front and upstream rear locations. Match the connector, thread size, and harness routing to the original sensor on the vehicle. For best results, inspect the exhaust bung and wiring path before installation, and verify the application against the vehicle’s emissions configuration.
