Direct Fit Oxygen Sensor for Volvo
NTK Direct Fit Oxygen Sensor 25585 is a specific-fit heated oxygen sensor built for downstream applications. It uses a threaded mounting design and a 4-wire configuration to match the original equipment style used on select Volvo models.
Key Features
- Heated oxygen sensor for faster operating response.
- Specific-fit design for direct replacement use.
- Threaded mounting with 18 mm thread diameter.
- 84.75-inch wiring harness length for application-specific routing.
- 4-wire sensor construction for signal and heater circuit operation.
Detailed Description
NTK 25585 is part of the Direct Fit Oxygen Sensor line, which focuses on application-specific replacement sensors rather than universal parts. This oxygen sensor is engineered for downstream placement on 1996-1998 Volvo 960, 1997-1998 Volvo S90, and 1997-1998 Volvo V90 applications. The design supports OE-style fit, form, and function for vehicles that require a threaded, heated sensor with the correct harness length and connector layout.
NTK is known for oxygen sensor manufacturing within the NGK family of products, and its OE-focused production approach is reflected in this part. This part cross-references Bosch 15099 and DENSO Auto Parts 234-4689 for the same application.
What It Is Used For
- Replacing a worn or slow-responding downstream oxygen sensor.
- Addressing oxygen sensor fault codes related to heater or signal performance.
- Restoring proper exhaust feedback for engine management.
- Correcting drivability issues tied to inaccurate air-fuel monitoring.
Installation Notes and Tips
Verify the downstream location, thread size, wire count, and harness length before installation. Use the vehicle’s original routing path to keep the harness away from heat and moving components. Confirm connector style and sensor placement against the existing unit before final installation on Volvo 960, S90, or V90 applications.
Quality Assurance
NTK tests oxygen sensors during manufacturing to help ensure quality and reliability that meet or exceed OE specifications.
