What to quote
State the oxygen sensor quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Nissan Sentra · Engine, Fuel, Cooling, Electrical & A/C
Specify Sentra oxygen sensor by engine and emission market. Retain bank and upstream or downstream position and sensor type, connector and lead so offers describe the same assembly.

| Record | Details to retain |
|---|---|
| Engine and emission market | Identify engine and emission market from the vehicle, installed assembly or readable label. |
| Bank and upstream or downstream position | Show bank and upstream or downstream position in photographs and retain measurements that distinguish the interfaces. |
| Sensor type, connector and lead | Specify sensor type, connector and lead together with every piece required in the quoted assembly. |
Upstream air-fuel ratio and downstream oxygen sensors have different functions and calibration.
For this oxygen sensor, keep chassis, production date, engine, transmission and sales market on the same record. The Sentra B13–B18 identification guide explains why a regional name alone is insufficient.
When this component is part of a mixed system order, use the fuel, cooling, electrical and a/c to separate neighboring assemblies.
| Reference | Application boundary |
|---|---|
| 22693-6LB0A | 2020–2025 Sentra upstream air-fuel ratio sensor example. Confirm the exact 2.0L application and upstream position. |
These numbers are identification examples, not universal Sentra applications. Confirm the installed reference and exact vehicle before approval.
Give every linked assembly its own specification; approving the oxygen sensor does not confirm the surrounding parts.
Sentra Catalytic Converter — Engine and emissions market define the catalyst; physical fit is not a regulatory compliance guarantee. Confirm engine, emission market and bank and manifold or underfloor position on its own order line.
Sentra Mass Air Flow Sensor — A matching connector does not prove the housing diameter or calibration family. Confirm engine and air-cleaner housing and sensor-only or housing assembly on its own order line.
Sentra Vapor Canister Purge Valve — A purge valve is not an EGR valve or canister-pressure sensor; hose routing and flow direction matter. Confirm engine and emission market and valve location and hose ports on its own order line.
State the oxygen sensor quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Protect the sensing tip and keep protective caps in place.
Before approving the oxygen sensor, agree sample and inspection requirements using the quality-control checklist. Return to the Sentra parts directory for other systems.
For oxygen sensor requirements on other vehicles, compare the vehicle sensor directory. Keep the Sentra specification and every other approved model on separate order lines.
