Description

Fuel Pressure Sensor 202V27421-0263

Functions:

1.Real-Time Pressure Monitoring

Measures fuel pressure in the rail (typical range 180–320kPa), converting physical pressure to electrical signals (0-5V or 4-20mA) transmitted to the ECU.

2.Closed-Loop Pressure Control

Cooperates with the ECU to dynamically adjust fuel pump operation, while diverting excess fuel to the tank via an overflow valve, maintaining consistent injection pressure (±2% tolerance).

3.Failure Protection

Triggers ECU alerts or limp-mode if pressure anomalies occur (e.g., blockages/leaks), preventing engine misfire or combustion inefficiency.

Applications

1.Diesel Fuel System Management

Integrated with high-pressure common rail engines (e.g. MAN D26, Mercedes OM47X), monitoring rail pressure (200-2500bar) to ensure precise combustion.

2.Emission Compliance

Critical for China VI/Euro VI standards:Optimizes injection timing via ECU to reduce PM/NOx.Enables accurate fuel dosing during DPF regeneration.

3.Failure Prevention

Detects fuel circuit faults (e.g., clogged filters/leaks), triggering DTCs (e.g., P0193) to prevent:Sudden power loss (Limp Mode).High-pressure pump damage.
