Weichai Common Rail Fuel Pressure Sensor 612600081585

The 612600081585 Common Rail Fuel Pressure Sensor serves as a vital feedback element in electronically controlled diesel fuel systems. By measuring fuel rail pressure across varying load demands, this Weichai fuel sensor enables the ECU to maintain optimal pressure regulation via the fuel metering valve and high-pressure pump, ensuring clean fuel combustion and engine efficiency.

Manufactured in ISO9001-certified facilities using piezoresistive sensing elements housed in a stainless steel body, the 612600081585 sensor withstands extreme fuel pressure spikes up to 2,000+ bar and harsh engine bay temperatures. Replacing a failing, shorted, or drifting sensor with a factory-tested 612600081585 unit restores engine power output, eliminates rough idling, and prevents unexpected engine derating or fault codes.

Technical Specifications

Key Features and Benefits

• High-Accuracy Piezoresistive Element: Delivers rapid, highly accurate pressure signal responses to the ECU for fine-tuned injection metering.
