Description
Engineered specifically for Nissan’s gasoline and diesel engine platforms, this BOSCH Mass Air Flow (MAF) Sensor utilizes advanced hot-film anemometer technology to measure the precise mass of air entering the engine. Built to match exact Original Equipment (OE) specifications, it delivers rapid response times and high signal accuracy directly to the Engine Control Unit (ECU), ensuring an optimal air-fuel ratio. Designed with superior resistance to intake contamination and temperature fluctuations, this sensor eliminates engine hesitation, rough idling, excessive fuel consumption, and black exhaust emissions. It is an essential, high-demand replacement part for auto parts importers, wholesale distributors, and Nissan service specialists worldwide.
Technical Parameters
| Category | Specifications & Technical Details |
| Measuring Mass Flow Range (Qm) | Specification: 10 kg/h to 800 kg/h (depending on engine displacement and naturally aspirated / turbocharged configuration) Technical Analysis: Precisely covers engine intake air measurement requirements from low idle to wide open throttle (WOT), with a wide dynamic response range. |
| Signal Output & Measuring Accuracy | Specification: 1.0V – 4.8V DC analog voltage output (or 0–5kHz digital frequency pulse), total measurement error ≤ ±2.0% Technical Analysis: Ultra-low signal drift delivers highly linear air mass data to the ECU in real time across the full flow range, ensuring precise air-fuel ratio control at the optimal stoichiometric value. |
| Response Time (τ0.9) | Specification: Dynamic response time ≤ 15 ms Technical Analysis: Based on a MEMS hot-film micro-sensing chip, delivering millisecond-level response to intake air changes when the driver presses the accelerator (sudden throttle change), completely eliminating acceleration lag and misfire during hard acceleration. |
| Intake Temperature & Pressure Compensation | Specification: Operating ambient temperature -40°C to +125°C, with built-in intake air temperature (IAT) sensor (NTC thermistor 2.2kΩ @ 25°C) Technical Analysis: Automatically corrects physical changes in air density under high-altitude low-pressure or extreme cold / heat environments, ensuring the ECU receives true “air mass” data rather than simple “volume” data. |
| Operating Voltage & EMC/ESD Protection | Specification: Rated supply voltage 12V DC (operating voltage range 9V – 16V DC), quiescent current < 80 mA; compliant with ISO 7637 automotive electromagnetic compatibility and electrostatic discharge (ESD) protection standards. Technical Analysis: Withstands vehicle electrical voltage fluctuations and high-voltage surges, preventing high-frequency electromagnetic interference from ignition coils and alternators in the engine bay from causing signal distortion. |
Applicable Car Brands & Models
Common warning indicators include engine hesitation during acceleration, rough or surging idling, unexpected engine stalling, poor fuel economy, hard starting, and an illuminated Check Engine Light (CEL) with fault codes such as P0101, P0102, or P0171 (System Too Lean).
Yes, Bosch is a leading Original Equipment Manufacturer (OEM). Bosch MAF sensors for Nissan are engineered to exact factory dimensions, flow-rate curves, and signal output parameters, enabling 100% direct plug-and-play replacement without ECU recalibration.
While light dust can sometimes be cleared using a specialized MAF sensor cleaner, internal electronic degradation, thermal element breakdown, or heavy oil contamination from aftermarket air filters requires a complete replacement with a new OE-quality unit to restore proper air-fuel metering.
Minimum Order Quantity (MOQ) depends on specific part numbers (SKUs). For fast-moving stocked SKUs, the MOQ starts as low as 10–20 units. Lead times typically range from 3–5 business days for in-stock items to 15–30 days for factory bulk orders.
