Nissan Paladin Air Flow Meter AFH45M46 Intake Sensor Original Quality Replacement

This AFH45M46 air flow meter uses the same platinum wire hot-film sensing element as OEM; housing made of high-temperature engineering plastic; measured signal response with OEM difference within ±2%; long-term stability verified by 300 hours continuous operation; a high-quality aftermarket part that can be directly replaced. OEM numbers correspond to AFH45M46, AFH45469520, AFH55M10, AFH55M11; fits Nissan Pathfinder 2.4L and some VG30E-equipped models. Function: detects intake mass and sends voltage signal to ECU to influence injection pulse width and ignition timing; if idle is rough or acceleration is choppy, replacement restores air-fuel ratio control accuracy. Installation requires disconnecting battery negative, loosening intake hose clamp with Phillips screwdriver, unplugging old sensor, plug in, and avoid touching sensing membrane; entire process about 15 minutes; average repair shop skill level.
