NTK 24690 Oxygen Sensor - Upstream

Direct Fit Oxygen Sensor Overview

NTK 24690 is a direct fit heated oxygen sensor built for specific applications with threaded mounting and a 4-wire design. It is engineered for accurate exhaust feedback and OE-style fitment on select Mitsubishi models.

Fits 2006-2012 Mitsubishi Eclipse, upstream. Fits 2004-2012 Mitsubishi Galant, upstream. This NTK oxygen sensor 24690 is a specific-fit replacement for applications that require an 18 mm thread diameter and an 18-inch wiring harness length.

Key Features

• Heated oxygen sensor for faster operating response.
• Specific-fit design for direct replacement applications.
• Threaded mounting with 18 mm thread diameter.
• 4-wire configuration for controlled signal output.
• 18-inch wiring harness length for application-specific routing.

Detailed Description

NTK 24690 belongs to the Direct Fit Oxygen Sensor line, which focuses on application-specific replacement parts with OE-style form and function. NTK uses ceramic-based sensor technology and manufacturing controls from raw material through finished product, and each sensor is tested during production to meet or exceed OE specifications. For Mitsubishi Eclipse and Mitsubishi Galant applications, this part supports upstream exhaust monitoring where precise air-fuel feedback is required. The NTK 24690 is also referenced by cross numbers such as Bosch 15582 and DENSO Auto Parts 234-4316 for the same application.

What It Is Used For

• Replacing a failed upstream oxygen sensor.
• Restoring accurate exhaust gas feedback to the engine control system.
• Addressing check engine light conditions related to sensor performance.
• Correcting drivability issues tied to improper air-fuel mixture control.
• Replacing a sensor with worn wiring, heater, or signal response.

Installation Notes and Tips

Verify the upstream location, thread diameter, and harness length before installation. Confirm the connector style and wire count match the original sensor on the vehicle. Use the fitment notes for cylinder-bank application details on Mitsubishi Eclipse and Mitsubishi Galant models.

Quality Assurance

NTK states that these oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications. The Direct Fit Oxygen Sensor line is backed by NTK’s OE-focused manufacturing approach and application coverage.
