Fitment

Please Note: NGK Direct Fit 4-Wire A/F Sensor, part 24850 (stored MPN ngk24850). Legacy title 'NGK Toyota Sienna 2013-2011 Direct Fit 4-Wire A/F Sensor' had reversed years - normalized and bracketed to [11-13 Toyota Sienna] (legacy application scope kept verbatim). TITLE/FITMENT CONFLICT FLAGGED FOR LEO: the stored fitment list (57 entries) is dominated by Subaru Legacy/Outback 2015-2024 applications with Toyota Sienna entries also present, and no second source found in this run cleanly confirms either scope for part 24850 - neither scope was written into the title beyond the legacy wording, per the Correction Standard. Stored attributes: CARB acknowledgement required, Prop 65 Y. Notes-only: no fitment bucket written.

Description

This NGK Direct Fit 4-Wire A/F Sensor, part 24850, is an NTK direct-fit air-fuel ratio sensor for the 2011-2013 Toyota Sienna application named in the title. Per the stored NTK copy, wideband oxygen (air-fuel ratio) sensors produce a linear output signal that allows the ECU to determine exactly how rich or lean the engine is running and make continuous, precise adjustments of the air-fuel mixture to stay closest to stoichiometric.

Features:

  • NTK is the world's largest supplier and manufacturer of original equipment oxygen sensors, per the stored NTK copy
  • Extensively tested during manufacturing to guarantee quality and reliability that meets or exceeds OE specifications, per the stored copy
  • NTK uses state-of-the-art technology enabling control of the ceramic used in the sensor from raw material to finished product, per the stored copy

Fitment:

  • 57 entries in the stored fitment list: a broad shared list dominated by Subaru Legacy and Outback 2015-2024 applications, with Toyota Sienna entries also present - this conflicts with the legacy Sienna title scope and was kept verbatim pending Leo's decision (see Fitment Notes)
  • Confirm by part number 24850 before ordering

Q&A:

  • Q: Does this fit my 2011-2013 Toyota Sienna? A: This sensor, part 24850, is listed for the 2011-2013 Toyota Sienna application in the title; confirm part number 24850 before ordering.
  • Q: What is in the box? A: One NGK / NTK direct-fit 4-wire air-fuel ratio sensor, part 24850 (1 unit per SKU where the stored listing states it).
  • Q: What does an air-fuel ratio sensor do? A: Per the stored NTK copy, it produces a linear output signal so the ECU can determine how rich or lean the engine is running and adjust the air-fuel mixture to stay closest to stoichiometric.
