The selected Pathfinder R51 MAF sensor is restricted to the listed 4.0L VQ40DE petrol, 4WD automatic application. Establish that scope before using the connector photograph as a selection shortcut.
A Pathfinder badge does not identify the fuel type, engine or gearbox. Nor does a five-contact description establish every sensor used across R51 variants.
Confirm the JLWR51 petrol record
The selected R51 VQ40DE five-pin sensor uses reference 22680-7S000. Its listed Australian JLWR51 ST, ST-L and Ti applications run 07/2005–05/2010.
Keep VIN, actual build month, engine and automatic-transmission details with the original reference. This offer does not establish a diesel application or another Pathfinder specification outside that record.
Compare the five-contact insert with the original
Match the five-contact connector, two mounting holes, flat sensing insert and fitted seal. Start with the full sensor so a plug close-up remains associated with the same unit.
Compare corresponding viewing directions. An obscured seal or connector detail should prompt a clearer photograph rather than an assumption based on a similar Nissan part. The contact count is an identity check, not a wiring diagram or test specification.
Recognise what sensor only excludes
The package contains one sensor. The air intake housing, wiring and fitting screws are excluded. If the repair also concerns the housing or loom, define that requirement separately with the installer.
This article does not diagnose an airflow reading, running complaint or warning light. Identify the fault before selecting a replacement, and follow the correct vehicle-specific workshop procedure.
Keep the application and photos together
Send the vehicle identifiers, original number and accessible labelled images of the full sensor, connector, flange and seal. Include the petrol engine and transmission in the enquiry and state any mismatch before ordering. Do not infer fitment from the shared model name alone.
