NTK Oxygen Sensor 22033 is a direct fit, heated oxygen sensor built for specific applications in select Ford and Mazda vehicles. It is engineered for accurate exhaust feedback, proper connector fit, and OE-style replacement performance on the listed upstream positions.

Key Features

• Direct fit oxygen sensor for specific applications
• Heated sensor design for faster operating response
• 3-wire configuration with a 13.7500 wiring harness length
• Threaded mounting with an 18.000 thread diameter
• OE-focused fit, form, and function from NTK
• Extensively tested during manufacturing for quality and reliability

Product Details

NTK part number 22033 is part of the Direct Fit Oxygen Sensor line, a product line focused on streamlined coverage and OE-style replacement fitment. NTK draws on its ceramics expertise and original equipment sensor manufacturing experience to produce sensors with controlled ceramic construction from raw material through finished product. This oxygen sensor is intended for upstream locations on 1996-1997 Ford Probe, 1996-1997 Mazda 626, and 1996-1997 Mazda MX-6 applications, including Bank 1 Sensor 1 and rear manifold configurations where listed. If you are replacing a worn sensor on a Ford Probe or Mazda 626, NTK 22033 provides a direct replacement path without universal-fit guesswork.

This part cross-references Bosch 13284 and DENSO Auto Parts 234-3010 for the same application.

Common Issues This Part May Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a failing upstream sensor
• Rough idle or hesitation caused by inaccurate exhaust readings
• Emissions test failure tied to sensor response issues
• Connector or fitment problems from a non-specific replacement sensor

Installation Notes and Tips

Confirm the vehicle year, make, model, and sensor position before ordering. This NTK oxygen sensor uses a threaded mounting style and a 3-wire heated design, so match the connector routing and harness length to the original part. For best results, inspect the exhaust threads and wiring path before installation, and verify the upstream location specified for your Ford Probe, Mazda 626, or Mazda MX-6 application.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer and tests these sensors during production to help ensure reliability and OE-spec performance. The Direct Fit Oxygen Sensor line is built to support accurate replacement fitment for import and domestic applications.
