NTK 24047 Oxygen Sensor - Downstream or Upstream

NTK Direct Fit Oxygen Sensor 24047

NTK 24047 is a direct fit heated oxygen sensor built for specific applications in the Toyota Camry, Toyota Solara, and Scion tC. It uses a 4-wire, threaded design with a 15-inch wiring harness and 18 mm thread diameter for OE-style replacement on the listed positions.

Direct Fit Sensor Line

NTK Direct Fit Oxygen Sensors are part of NTK’s OE-focused sensor line, developed with ceramic manufacturing expertise and application coverage for import and domestic vehicles. This product line emphasizes correct fit, form, and function for replacement work where the original sensor location and connector style matter.

Key Features

• Heated oxygen sensor for faster operating temperature
• Specific fit design for the listed vehicle applications
• 4-wire configuration
• Threaded mounting type with 18 mm thread diameter
• 15-inch wiring harness length
• OE-style replacement for emissions system service

Vehicle Fitment

• Fits 2011-2013 Scion tC, downstream. B1S2 oxygen sensor meets OEM standards; direct fit oxygen sensor.
• Fits 2004-2006 Toyota Camry, upstream. Located before underfloor rear catalyst, B1S2 oxygen sensor for federal emissions; OE manufacturer: NTK.
• Fits 2004-2006 Toyota Solara, downstream. B1S2 oxygen sensor meets OEM standards; direct fit oxygen sensor.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn sensor
• Slow sensor response during closed-loop operation
• Emissions test failures tied to sensor output
• Replacement of a damaged or aging upstream/downstream sensor

Installation Notes

Verify the sensor position before ordering, since this part is listed for upstream and downstream locations depending on application. Confirm the 4-wire connector style, threaded mounting, and harness length against the original sensor on the vehicle. For 2004-2006 Toyota Camry applications, the fitment notes specify the sensor location before the underfloor rear catalyst.

Quality Assurance

NTK states that its oxygen sensors are manufactured and tested to meet or exceed OE specifications. As part of the NGK family of products, NTK focuses on OE application coverage and sensor technology for import and domestic vehicles. This part cross-references Bosch 13355 for the same application.
