NTK 24601 Oxygen Sensor - Upstream

Direct Fit Oxygen Sensor Overview

The NTK 24601 is a direct fit heated oxygen sensor built for specific import applications that require threaded installation and OE-style signal control. It is engineered for accurate air/fuel ratio feedback and consistent performance in emission control systems.

Compatible With Honda Passport, Isuzu Rodeo, Isuzu Trooper, Asuna Sunfire, Geo Storm, Isuzu Impulse, and Isuzu Stylus in upstream applications. The NTK 24601 is a specific-fit oxygen sensor with a 4-wire design and 18 mm thread diameter for applications that match the original sensor configuration.

Key Features

• Heated oxygen sensor design for faster operating response.
• Specific-fit construction for direct replacement applications.
• Threaded mounting type with 18 mm thread diameter.
• 12.2500 wiring harness length for matched routing.
• 4-wire configuration for OE-style sensor communication.

Detailed Application Notes

NTK 24601 is part of NTK’s Direct Fit Oxygen Sensor line, which focuses on application-specific coverage and OE-style fit, form, and function. NTK is part of the NGK family of products and is known for oxygen sensor manufacturing with ceramic-based technology and extensive production testing. This part cross-references Bosch 13030 and DENSO Auto Parts 234-4006 for the same application.

Fits 1994-1995 Honda Passport, upstream. Fits 1993-1995 Isuzu Rodeo, upstream. Fits 1992-1995 Isuzu Trooper, upstream. Fits 1993 Asuna Sunfire, upstream. Fits 1992-1993 Geo Storm, upstream. Fits 1992 Isuzu Impulse, upstream. Fits 1992 Isuzu Stylus, upstream.

Common Issues This Part May Address

• Faulty oxygen sensor readings that affect fuel mixture control.
• Delayed sensor response during closed-loop operation.
• Emission system fault codes related to upstream sensor performance.
• Rough idle or drivability issues caused by inaccurate air/fuel feedback.

Installation Notes and Quality Assurance

Verify the vehicle’s original sensor connector, thread size, wire count, and upstream location before installation. Confirm the application matches the original fitment and sensor configuration for Honda Passport, Isuzu Rodeo, or Isuzu Trooper models.

NTK tests oxygen sensors extensively during manufacturing to help ensure quality and reliability that meet or exceed OE specifications.
