NTK 22534 Oxygen Sensor - Upstream

Direct-Fit Oxygen Sensor

NTK 22534 is a direct-fit oxygen sensor built for specific upstream applications. It uses a threaded mounting design and a non-heated, single-wire configuration with a 15.75-inch harness length for targeted replacement work.

• Specific-fit oxygen sensor for direct replacement applications
• Non-heated design with one wire and threaded mounting
• 15.75-inch harness length for application-specific routing
• NTK 22534 is engineered for OE-style fit, form, and function

Application Details

This oxygen sensor is used in upstream air/fuel ratio monitoring on a wide range of classic import and domestic vehicles. Compatible applications include Ford Bronco, Ford F-150, Jeep Cherokee, and Merkur XR4Ti, with fitment listed for 1981-1989 model years depending on the vehicle. The NTK 22534 part number appears across multiple OE-equivalent applications, including Ford and Jeep platforms, and this part cross-references Delphi ES10132 and Spectra Premium OS5143 for the same application.

What It Helps Address

• Faulty upstream oxygen sensor readings
• Incorrect air/fuel ratio feedback to the engine control system
• Check engine light concerns related to sensor performance
• Connector or harness mismatch on specific-fit replacements
• Wear-related sensor degradation in older emissions systems

Installation Notes and Tips

Verify the vehicle’s upstream sensor location, connector style, and thread size before installation. This NTK 22534 sensor is a specific-fit replacement, so matching the original harness length and mounting style is important for proper routing and installation. Confirm the application details for your Ford, Jeep, or Merkur model before ordering.
