Upstream air-fuel sensor
For the upstream air-fuel sensor line, document position: Upstream or downstream, bank and physical location on the exhaust. Add required quantity, included hardware, packing and destination.

Fuel, Intake and Emission · decision page
The words oxygen sensor and air-fuel sensor do not establish position. Record bank, upstream or downstream location, connector and build information.
Decision matrix
Every field should describe the specific requested item, not merely the vehicle family.
Searchable reference evidence
These documented numbers are identification starting points, not universal fitment or a stock claim. Confirm VIN/model code, production date, market, powertrain, side and original-part evidence before quotation.
Installing a sensor with a matching thread but the wrong calibration or position can create diagnostic faults.
Request scope
Similar buyer terminology can describe a different kit, side, finish or packing scope.
For the upstream air-fuel sensor line, document position: Upstream or downstream, bank and physical location on the exhaust. Add required quantity, included hardware, packing and destination.
For the downstream oxygen sensor line, document build: Japan or North America build where shown by the vehicle record. Add required quantity, included hardware, packing and destination.
For the left or right bank where applicable line, document powertrain: Gasoline or hybrid and FWD or AWD where relevant. Add required quantity, included hardware, packing and destination.

Buyer questions
Use these answers to prepare a clearer first request.
No. Send the production period, market, powertrain or drivetrain evidence and the part-specific checks listed on this page.
Record position, build, powertrain, connector together with quantity, packing, destination port and the preferred Incoterm.
Use them as search and identification references within the stated catalog scope. They do not confirm universal fitment, current stock, price or supersession without a reviewed vehicle and part record.
Build a traceable request
Include vehicle generation or production period, market, engine or hybrid designation, drivetrain, part reference or photos, position, quantity, packing and destination. A listing is not automatic fitment or availability confirmation.
