This is a New Old Stock (NOS) Mass Air Flow (MAF) sensor designed specifically for the Nissan Patrol GU Y61 fitted with the TB45 petrol engine. Located in the air intake system against the air filter housing, the MAF sensor is a critical component that measures the volume and density of air entering your engine. This data is essential for the ECU to accurately manage the fuel injection and ignition timing for optimal performance and efficiency.

A failing MAF sensor can cause a range of engine problems, from a rough idle and poor fuel economy to hesitation and stalling. This NOS part provides the precise, factory-level calibration your engine's computer requires. Unlike cheaper aftermarket alternatives that can send incorrect data, this genuine-spec sensor ensures your Patrol runs exactly as it should, preventing poor performance and potential damage to other engine components.

Important Notes:

It is highly recommended to inspect or replace the engine air filter when installing a new MAF sensor. A contaminated filter is a common cause of MAF sensor failure. You should also check the intake hoses for any cracks or leaks, as these can allow unmetered air to enter the system and cause running issues.
