NTK 24060 Oxygen Sensor - Downstream

Direct-fit oxygen sensor

NTK 24060 is a direct-fit heated oxygen sensor built for specific applications and threaded mounting. It is engineered for reliable exhaust monitoring and OE-style fit, form, and function. Compatible with Toyota Highlander downstream applications, this sensor supports accurate air-fuel feedback in the exhaust stream.

• Heated oxygen sensor for faster operating response.
• Specific-fit design for straightforward replacement.
• Threaded mounting with an 18.000 mm thread diameter.
• 4-wire configuration with a 27.5 in. harness length.
• Built to meet or exceed OE specifications during manufacturing.

Fitment details

Fits 2014-2019 Toyota Highlander, downstream. This application is listed as B1S2 and direct fit. The NTK 24060 is a strong match for Toyota Highlander owners replacing a downstream oxygen sensor with an OE-style part number reference.

What it helps address

• Check engine lights related to downstream oxygen sensor performance.
• Incorrect exhaust oxygen readings affecting fuel control.
• Slow sensor response from a worn heated oxygen sensor.
• Fitment issues from using a universal sensor instead of a specific-fit part.

Installation notes and quality

Use the threaded mounting style and harness length to confirm application details before installation. Verify connector routing and exhaust location against the vehicle’s original sensor layout. NTK 24060 is manufactured and tested to meet or exceed OE specifications, and NTK is recognized as a major original equipment oxygen sensor supplier. This part cross-references DENSO Auto Parts (e.g., 234-4948) for the same application.
