Intake Pressure Sensor VG1099090112 Sinotruk Sitrak

Product Introduction

This Intake Pressure Sensor VG1099090112 is an OEM engine management component for heavy-duty diesel engines (e.g., Sinotruk Howo, Weichai WP series). It features a compact black plastic housing with a precision pressure-sensing element, a green sealing O-ring for leak-proof installation, and a waterproof electrical connector. Engineered to accurately measure the absolute pressure of the intake manifold, it provides critical data to the engine control unit (ECU) for optimal fuel injection and combustion control. Manufactured to strict OEM specifications, it ensures reliable performance in high-vibration, dusty, and high-temperature engine environments.

Core Function

1. Precision Pressure Measurement: Accurately detects intake manifold absolute pressure (MAP) and transmits real-time data to the ECU, enabling precise calculation of air mass flow for optimal fuel injection.

2. Engine Performance Optimization: Provides critical input for the ECU to adjust fuel delivery, ignition timing, and turbocharger boost pressure, improving engine efficiency, power output, and emissions control.

3. Durable Construction: The sealed housing and corrosion-resistant internal components resist dust, moisture, and temperature extremes, ensuring consistent performance in harsh operating conditions.

4. Leak-Proof Installation: The integrated green O-ring ensures a tight, reliable seal at the intake manifold, preventing air leaks that could compromise sensor accuracy.

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