Product Description

3510202910

The 03510202910 mass air flow sensor (MAF) is a hot-wire high-precision intake air detection component developed for VW Group 1.9TDI PD diesel engines, installed between air filter housing and intake pipeline. It precisely measures intake air mass and converts airflow data into standard electrical signal to ECU. Based on real intake air data, ECU adjusts diesel injection quantity and injection timing, optimizes diesel combustion efficiency, cuts black smoke emission, reduces fuel consumption and stabilizes idle & acceleration performance, serving as direct OEM replacement part for HYUNDAI.

Key Features

Material:Constructed from a special material that delivers excellent wear resistance and anti-deformation performance. It regulates the air flow entering the engine, thus boosting efficiency and power output.
Function:Precise measurement of throttle valve position optimizes fuel efficiency and engine performance, making every drive more efficient and cost-effective.
Installation:This throttle position sensor requires no special complex tools or vehicle modifications and can be fully installed within minutes.
Customer Service:Please feel free to contact us if you have any questions about the product. Our customer service team is highly knowledgeable about product compatibility and installation, and will provide competent, professional answers to all your inquiries.
Compatibility:Kindly carefully review all product specifications before placing your order to confirm compatibility with your vehicle.

Performance Indicators

Airflow Detection Accuracy: Standard tolerance ≤±3% of OEM benchmark; contaminated or aged hot-wire core triggers measuring deviation, excessive diesel consumption and black exhaust smoke.
Linear Signal Output: Qualified part outputs linear voltage matching real intake airflow; defective sensor leads to signal jump/loss and fault codes P0101/P0102.
Ambient Temperature Adaptability: Normal working range: -40℃ ~ +125℃; inferior products have obvious data drift under extreme cold startup or high engine bay temperature.
Rated Service Mileage: Standard service lifespan:75,000~150,000 KM; overdue clogged air filter, crankcase oil backflow and long-term high-load driving shorten service life greatly.
Working Voltage: Rated 12V DC vehicle power supply; overvoltage will permanently burn internal hot-wire sensing chip and control circuit.
