The NTK 24456 is a 3-wire heated switching oxygen sensor built as a universal-fit replacement for Toyota applications. NTK (NGK's sensor division) supplies oxygen sensors to automakers, and this sensor carries OE-style water-resistant connectors, a contaminant-resistant overcoat on the element, and vibration and thermal shock testing. It suits owners of older Toyotas chasing a check-engine code for a lazy or dead upstream sensor. Against cheaper no-name universals, the draw is OE-grade ceramic and connectors; the trade-off is that universal sensors need the old connector spliced or matched, so fit depends on the harness, not just the threads.

Buyers on Advance Auto Parts report it as an exact OEM replacement on older Toyotas, with the engine code clearing right away. The common note is that the sensor itself is easy; removing the old, seized sensor is the hard part.
This is a heated, 3-wire switching oxygen sensor with a universal fit. Oxygen sensors are part of the vehicle's on-board diagnostic system. They send constant closed-loop feedback to the ECU, which helps control the air-fuel ratio. They can also alert OBDII systems to possible problems with fuel delivery or catalytic converter efficiency.
The sensor is built on original-equipment designs and engineered for the aftermarket to match OE fit, form and function. Its ceramic element has a 3-stage contaminant-resistant plasma jet and deposit trap overcoat that protects against element poisoning. A dual-coated platinum interface and a thinner ceramic element give fast light-off and response times.
Development includes vibration and thermal shock testing, and units are tested during manufacturing. It comes with OE-specified water-resistant connectors and harness accessory hardware for installation.
