NTK 24534 Oxygen Sensor - Upstream

Direct-Fit Oxygen Sensor

NTK Oxygen Sensor 24534 is a specific-fit, heated oxygen sensor built for direct replacement applications. It is engineered for threaded mounting and uses a 4-wire design with an 8.75-inch harness for a clean, application-specific installation.

Compatible with 1990-1994 Hyundai Sonata upstream Bank 1 Sensor 1 oxygen sensor applications, this part number 24534 supports accurate exhaust feedback for the engine management system. NTK 24534 is part of the Direct Fit Oxygen Sensor line, which focuses on OE-style fit and coverage for import and domestic vehicles.

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct replacement use
• Threaded mounting with 18 mm thread diameter
• 4-wire configuration for the listed application
• 8.75-inch harness length for routing to the connector

Detailed Application Coverage

Fits 1990-1994 Hyundai Sonata, upstream. This oxygen sensor is intended for Bank 1 Sensor 1 placement on the listed Hyundai Sonata application and is identified by part number 24534. NTK’s Direct Fit Oxygen Sensor line is built around OE-style fit, form, and function, with manufacturing controls that support consistent sensor performance.

What It Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel feedback from a worn upstream sensor
• Slow sensor response during closed-loop operation
• Fitment issues from using a universal sensor instead of a specific-fit part

Installation Notes and Quality

Install as a threaded oxygen sensor in the specified upstream location for the listed application. Verify connector routing, harness length, and thread size before installation. Part number 24534 is manufactured by NTK, a major original equipment oxygen sensor supplier, and is extensively tested during production to meet or exceed OE specifications.
