Intake Air Pressure 612630120004 SHACMAN

Product Introduction

This Intake Air Pressure Sensor 612630120004 is an OEM engine management component for heavy-duty diesel engines (e.g., Weichai WP series). It features a compact black PBT-GF30 plastic housing with a precision pressure-sensing element, a green O-ring seal, and a 3-pin electrical connector. The sensor is engineered to accurately measure intake manifold pressure and temperature, providing critical data to the engine control unit (ECU) for optimal fuel injection and combustion efficiency. Manufactured to strict OEM specifications, it ensures reliable performance in high-vibration, high-temperature, and corrosive engine environments.

Core Function

1. Precision Measurement: Accurately detects intake manifold absolute pressure (MAP) and temperature, transmitting real-time data to the ECU for precise control of fuel injection quantity and ignition timing.

2. Engine Performance Optimization: Enables the ECU to adjust air-fuel ratio dynamically, improving combustion efficiency, reducing emissions, and enhancing overall engine performance and fuel economy.

3. Durable Construction: The PBT-GF30 housing and high-grade O-ring seal resist oil, coolant, and temperature extremes, while the shock-resistant sensing element ensures stable operation under heavy vibration.

4. Easy Installation: Features factory-matched mounting points and electrical connectors for a seamless, plug-and-play installation, minimizing vehicle downtime during service.

5. Perfect Compatibility: Strictly adheres to OEM design standards, ensuring it matches the original sensor’s dimensions, output signal, and communication protocol for full system compatibility with the engine management system.
