NTK 24042 Oxygen Sensor - Upstream

Direct Fit Oxygen Sensor for Honda Applications

The NTK 24042 direct fit oxygen sensor is a heated, threaded replacement built for specific-fit Honda applications. It is engineered for upstream use on select Honda Accord and Prelude models, with OE-equivalent design details that support accurate exhaust feedback and proper engine management.

As part of the NTK Direct Fit Oxygen Sensor line, this sensor reflects NTK’s focus on application coverage, ceramic manufacturing control, and OE-style fit, form, and function. The result is a replacement oxygen sensor for Honda Accord and Honda Prelude service work where exact connector and thread specifications matter.

Key Features

• Direct fit oxygen sensor for specific Honda applications
• Heated sensor design for faster operating response
• 4-wire configuration
• 18 mm thread diameter with threaded mounting
• 16.25 in. wiring harness length
• Upstream placement for Bank 1 Sensor 1 applications
• OE-equivalent design for select Honda Accord and Prelude models

Detailed Description

NTK part number 24042 is a direct fit oxygen sensor for 1990-1997 Honda Accord and 1992-1995 Honda Prelude upstream positions. It is specified for B1S1 service on Accord and Prelude applications, including female connector and OE design references noted in the fitment data. If you are replacing an upstream oxygen sensor on a Honda Accord or Honda Prelude, this NTK 24042 sensor is built to match the original application requirements.

NTK is known for oxygen sensor manufacturing across import and domestic coverage, and this Direct Fit Oxygen Sensor line is built to streamline replacement selection while maintaining OE-style application accuracy. This part cross-references Bosch 13322 and DENSO Auto Parts 234-4094 for the same application.

Vehicle Fitment

• Fits 1994-1997 Honda Accord, upstream; B1S1; Female Connector; OE Equivalent Design; Direct Fit Oxygen Sensor
• Fits 1994-1995 Honda Prelude, upstream; OE design oxygen sensor fits Bank 1 Sensor 1 for air/fuel ratio.; Direct Fit Oxygen Sensor
• Fits 1990-1993 Honda Accord, upstream; B1S1; Female Connector; OE MFR: NTK; Direct Fit Oxygen Sensor
• Fits 1992-1993 Honda Prelude, upstream; Bank 1 Sensor 1 Oxygen Sensor; Direct Fit Oxygen Sensor

Common Replacement Concerns

• Check engine light related to upstream oxygen sensor performance
• Incorrect air/fuel ratio readings on Honda Accord or Honda Prelude
• Slow sensor response from a heated oxygen sensor circuit
• Connector or thread mismatch during oxygen sensor replacement
• Emissions-related drivability issues tied to Bank 1 Sensor 1

Installation Notes and Tips

Confirm the upstream location, connector style, and 18 mm threaded mounting before installation. Verify the vehicle year and engine application against the listed Honda Accord and Honda Prelude fitments, and compare the original harness routing to the 16.25 in. lead length for proper installation clearance.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. The brand also emphasizes OE application coverage and ceramic manufacturing control from raw material through finished product.
