NTK 24033 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Direct Fit Oxygen Sensor for OE Applications

NTK Direct Fit Oxygen Sensor 24033 is a specific-fit, threaded oxygen sensor built for upstream air/fuel ratio monitoring on a range of import and domestic vehicles. With an 18 mm thread diameter, 18.5 in. wiring harness length, and a non-heated, 1-wire design, it supports OE-style replacement where the original sensor configuration matches.

Key Features

• Specific-fit oxygen sensor for direct replacement applications
• Non-heated, 1-wire design
• 18 mm threaded mounting type
• 18.5 in. wiring harness length
• OE-style fit, form, and function for selected upstream locations
• NTK part number 24033

Product Line Details

NTK Direct Fit Oxygen Sensors are part of NTK’s OE-focused sensor line. NTK applies ceramic manufacturing expertise and production controls from raw material through finished sensor, with extensive testing during manufacturing to support consistent performance and OE-level specifications.

Detailed Description

This NTK oxygen sensor is engineered for vehicles that use an upstream, non-heated sensor with a threaded mount and single-wire configuration. It is listed for applications such as 1988-1991 Honda Civic, upstream; 1986-1995 Suzuki Samurai, upstream; and 1986-1989 Honda Accord, upstream right or upstream left. It also covers additional applications including Acura Integra, Honda Prelude, and Suzuki Sidekick, making NTK 24033 a practical OE replacement choice for older Honda, Acura, Suzuki, and related platforms.

This part cross-references Bosch 12050 for the same application.

Common Issues This Sensor Addresses

• Faulty upstream oxygen sensor readings
• Check engine light related to air/fuel ratio monitoring
• Rough idle caused by inaccurate exhaust feedback
• Reduced fuel control from a worn sensor element
• Failed emissions inspection tied to sensor performance

Installation Notes and Tips

Verify the vehicle’s original sensor style before ordering, including upstream position, 1-wire configuration, and 18 mm thread size. This sensor is listed for specific-fit applications only, so match the year, make, model, and position exactly. On split-manifold applications such as certain Honda Accord and Prelude listings, confirm whether the vehicle uses upstream left or upstream right placement.

Quality Assurance

NTK manufactures oxygen sensors with OE application coverage and tests them during production to help meet or exceed original equipment specifications. The brand’s OE supplier background and ceramic sensor expertise support consistent fit and reliable operation in listed applications.
