NTK 22093 Oxygen Sensor - Downstream Right

Direct-Fit Oxygen Sensor

NTK Oxygen Sensor 22093 is a specific-fit, heated replacement sensor built for emission control applications. It uses a threaded mounting design and a 4-wire configuration with a 31.5-inch harness for a direct-fit installation.

Key Features

• Heated oxygen sensor design for faster operating response.
• Specific-fit construction for a direct replacement application.
• 4-wire configuration with a 31.5-inch wiring harness.
• Threaded mounting type with an 18 mm thread diameter.
• NTK 22093 is part of the Direct Fit Oxygen Sensor line.

Detailed Description

NTK 22093 is an OE-style oxygen sensor engineered for emission control performance and accurate exhaust feedback. As part of NTK's Direct Fit Oxygen Sensor line, it is built to match the original sensor's fit, form, and function while simplifying replacement on supported applications. This part cross-references Bosch 13581 and Delphi ES20065 for the same application. Fits 1995-2002 Mazda Millenia, downstream right. Fits 1995-2002 Mazda Millenia, downstream right.

Common Issues It May Solve

• Faulty oxygen sensor readings that can trigger emissions-related warning lights.
• Slow sensor response caused by a worn heated sensor element.
• Connector or harness mismatch on a specific-fit replacement job.
• Exhaust feedback problems affecting fuel control and emissions monitoring.

Installation Notes and Tips

Verify the downstream right application and confirm the 4-wire, threaded sensor configuration before installation. Match the harness length and thread diameter to the original unit to ensure proper fitment on the Mazda Millenia application. Use the vehicle's service information for removal and installation procedures.
