Import 89465-28290 Air Fuel Ratio Oxygen Sensor — Buy in wholesale FOB from Supplier in China

The 89465-28290 is a planar zirconia air fuel ratio oxygen sensor designed for gasoline engine applications, outputting a continuous voltage signal that enables the engine control unit to maintain stoichiometric combustion. Honchang Sensor supplies this unit with a two-year warranty and CE marking. The sensor operates on the principle of oxygen ion conduction through a ceramic element, comparing exhaust gas oxygen content against ambient air reference to generate a precise lambda signal.

The sensing element typically employs a thimble-shaped or planar zirconia ceramic doped with yttria stabiliser, with platinum electrodes applied to both the exhaust and reference sides. A built-in heater element reaches operating temperature rapidly to ensure closed-loop fuel control during cold starts. Standard industry practice for this Toyota-compatible part number specifies a hex size of 22 millimetres, thread specification of M18 by 1.5, and cable lengths that vary by application variant. The SORGHUM branded units from this supplier are intended for aftermarket replacement rather than original equipment fitment.

Buyers include independent auto parts distributors, repair workshop chains, and e-commerce retailers serving the Asia-Pacific and Middle Eastern markets. The 89465-28290 cross-reference suits multiple Toyota and Lexus models with 1.8 to 3.5 litre engines from the early 2000s. Importers should verify exact vehicle application compatibility, as connector types and cable routing differ across production regions. Payment instruments accepted include letter of credit, telegraphic transfer, Western Union, PayPal, and credit card, though minimum order quantities and unit pricing require direct confirmation with Honchang Sensor sales.

Honchang Sensor operates from Building B3, Wanda Plaza in Nansha District, Guangzhou, Guangdong Province, postal code 511400, China. The supplier lists itself as specialising in automotive sensors and electrical auto parts, with the SORGHUM brand applied to its oxygen sensor line.

The trust tier assigned is harbour, with a response rate of 0.00 percent and zero average response hours recorded. These figures suggest either a newly registered listing or limited platform engagement rather than active trading history verification. No factory audit certifications, ISO 9001 documentation, or production capacity figures are provided in the source data. Buyers should conduct independent due diligence on manufacturing capability, quality management system scope, and whether CE marking and ISO 9001 certification apply to the specific sensor models being quoted.
