Detailed Product Overview

NTK 24698 is a downstream oxygen sensor for the Mazda MX-5 Miata that matches the original equipment style used on the vehicle’s exhaust monitoring system. The heated design helps the sensor reach operating temperature quickly, while the specific-fit configuration supports straightforward replacement in the correct downstream location. If you are searching for a downstream oxygen sensor for 2006-2015 Mazda MX-5 Miata, NTK 24698 is built for that application.

This part cross-references Bosch 15786 and DENSO Auto Parts 234-4340 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to downstream oxygen sensor performance
• Incorrect exhaust oxygen readings from a worn sensor
• Reduced emissions monitoring accuracy
• Slow sensor response after extended service life
• Fault codes tied to the downstream sensor circuit

Installation Notes and Tips

Install NTK 24698 in the downstream oxygen sensor location specified for the 2006-2015 Mazda MX-5 Miata. Verify the threaded mounting point, wire routing, and connector match the original sensor before installation. Because oxygen sensors are exposed to heat and corrosion, inspect the exhaust bung and surrounding wiring during replacement.

Quality Assurance

NTK manufactures oxygen sensors with controlled ceramic technology and tests them during production to help meet or exceed OE specifications. The brand is a major original equipment oxygen sensor supplier, and the Direct Fit Oxygen Sensor line is built to support OE application coverage and consistent replacement quality.
