NTK 24788 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor Overview

The NTK 24788 is a direct fit heated oxygen sensor built for specific downstream applications. It is engineered for precise fit, stable signal performance, and OE-style replacement on import vehicles including Toyota Yaris and Mazda CX-3 applications.

Key Features

• Direct fit design for specific applications
• Heated oxygen sensor construction for faster operating response
• 4-wire configuration with threaded mounting
• 16.25-inch wiring harness length
• 18 mm thread diameter

Detailed Description

NTK 24788 is part of the Direct Fit Oxygen Sensor line, a product line focused on application-specific replacement rather than universal adaptation. The sensor uses a threaded mounting style and a heated design to match the requirements of listed downstream applications. As an OE-focused oxygen sensor from NTK, it is built to deliver the fit, form, and function expected for emissions system service on vehicles such as Toyota Yaris, Mazda CX-3, and Mazda MX-5 Miata.

NTK is known for oxygen sensor manufacturing across import and domestic coverage, and this part number reflects that OE application focus. This part cross-references Honda/Acura OE numbers (e.g., 89465WB001, P51C18861) for the same application.

What It Helps Address

• Faulty downstream oxygen sensor readings
• Check engine light concerns related to sensor performance
• Emissions monitoring issues caused by sensor degradation
• Slow sensor response in heated oxygen sensor circuits
• Replacement needs for a specific threaded oxygen sensor application

Installation Notes and Tips

Verify the connector style, thread diameter, harness length, and downstream location before installation. This NTK 24788 oxygen sensor is a specific-fit part, so matching the vehicle application and sensor position is essential for proper installation. Use the listed fitment data to confirm compatibility with the exact model and year.

Quality Assurance

NTK tests oxygen sensors during manufacturing to support quality and reliability that meet or exceed OE specifications. The brand’s OE-supplier background and ceramics expertise support consistent performance across listed applications.
