NTK 24505 Oxygen Sensor - Downstream or Upstream

Direct Fit Oxygen Sensor for Toyota and Geo

NTK 24505 is a direct fit oxygen sensor built for specific applications on select Toyota and Geo models. It uses a threaded mounting design, a 2-wire non-heated configuration, and a 19-inch wiring harness length for OE-style replacement on the listed upstream and downstream positions.

Key Features

• Direct fit oxygen sensor for specific vehicle applications
• Non-heated sensor type with 2-wire design
• 19.0000 wiring harness length
• 18.000 thread diameter with threaded mounting type
• OE-style fit, form, and function for emission control service
• NTK part number 24505

Product Details

NTK 24505 is part of the Direct Fit Oxygen Sensor line, a product line focused on application-specific replacement sensors for import and domestic vehicles. NTK develops oxygen sensors with ceramic control from raw material through finished product, then tests them during manufacturing to help ensure consistent performance and OE-level dimensional accuracy. This sensor is listed for 1992-1997 Toyota and Geo applications, including Fits 1995-1997 Toyota Corolla, upstream, Fits 1995-1997 Geo Prizm, upstream, Fits 1993-1995 Toyota MR2, downstream, Fits 1992-1993 Toyota Celica, downstream, and Fits 1992 Toyota MR2, downstream. The NTK 24505 is a practical choice when replacing an aging sensor on Toyota Corolla, Toyota MR2, Toyota Celica, or Geo Prizm emission systems.

This part cross-references Bosch (e.g., 12108) for the same application.

Common Issues This Sensor Can Address

• Faulty oxygen sensor readings that affect fuel control
• Check engine light concerns related to sensor performance
• Rough idle or drivability issues tied to air-fuel feedback
• Emissions test failures caused by a worn sensor
• Replacement needs for upstream or downstream sensor service

Installation Notes and Tips

• Verify the vehicle position before ordering: upstream or downstream applications are listed separately.
• Confirm the threaded mounting style and 18.000 thread diameter match the original sensor.
• Check harness routing and connector reach against the 19-inch wiring harness length.
• Use the vehicle’s exact year, make, model, and emissions configuration to confirm the correct application.
• For Toyota Corolla, Toyota MR2, Toyota Celica, and Geo Prizm service, match the listed position and notes before installation.

Quality Assurance

NTK manufactures oxygen sensors to meet or exceed OE specifications and tests them during production for quality and reliability. As part of the NGK family of products, NTK supports import and domestic emission control applications with OE application coverage and sensor technology.
