Vemo V10-72-1105 Sensor, fuel pressure

Vemo V10-72-1105 Fuel Pressure Sensor

The Vemo V10-72-1105 is a high‑performance fuel pressure sensor designed for modern gasoline and diesel engines across the Volkswagen Group, including Audi, VW, SEAT, Škoda, and Porsche platforms. It delivers precise, real‑time monitoring of fuel system pressure, enabling optimal engine performance, emissions control, and fuel efficiency.

Key Functionalities

• Accurate Pressure Measurement: Measures fuel pressure from the high‑pressure pump to the injectors with a tolerance of ±1 % over the full operating range.
• Wide Operating Range: Supports pressures up to 200 bar, suitable for both gasoline direct injection and diesel common rail systems.
• Fast Response Time: Less than 10 ms response ensures immediate feedback to the engine control unit (ECU) during rapid throttle changes.
• Robust Construction: Sealed housing protects against fuel, oil, and high temperatures up to 200 °C.
• Integrated Signal Conditioning: Built‑in amplifier and filtering reduce noise and improve signal integrity for the ECU.

The V10-72-1105 is engineered to fit a wide array of models. Below is an overview of supported vehicles, grouped by manufacturer:

The V10-72-1105 is a plug‑and‑play component that replaces the OEM sensor without requiring modifications to the fuel rail or ECU. Key installation steps include:

1. Disconnect battery and relieve fuel system pressure.
2. Remove the existing fuel pressure sensor from the fuel rail.
3. Insert the V10-72-1105, ensuring proper alignment of the sealing gasket.
4. Tighten to manufacturer torque specifications (typically 4.0 Nm).
5. Reconnect battery and perform a fuel system pressure test to confirm correct operation.

The sensor uses a standard 5‑wire configuration:

• Signal Wire (Red): Provides the analog voltage proportional to fuel pressure.
• Ground Wire (Black): Common ground reference.
• Power Supply (Yellow): 12 V DC from the vehicle’s electrical system.
• Signal Return (White): Completes the signal circuit.
• Optional Diagnostic Wire (Blue): Used in some models for advanced diagnostics.

• Enhanced Engine Calibration: Accurate pressure data allows the ECU to fine‑tune fuel injection timing and quantity, improving combustion efficiency.
• Reduced Emissions: Precise control of fuel delivery minimizes unburned hydrocarbons and NOx emissions.
• Improved Fuel Economy: Optimized injection reduces fuel consumption by up to 2 % in real‑world driving conditions.
• Reliability Under Stress: The sensor’s robust housing withstands high temperatures, vibration, and corrosive fuels, ensuring long service life.

The V10-72-1105 supports standard OBD‑II diagnostics. When connected to a compatible scan tool, the ECU can read real‑time pressure values, detect sensor faults (e.g., open circuit, short to ground), and log error codes such as P0130–P0140 for fuel pressure issues.

Manufactured in accordance with VAG Group quality standards, the V10-72-1105 undergoes rigorous testing:

• Pressure Calibration: Each unit is calibrated against a reference gauge to ensure ±1 % accuracy.
• Temperature Cycling: Tested from –40 °C to +120 °C to simulate extreme operating conditions.
• Vibration and Shock Testing: Meets automotive industry vibration standards (ISO 16750‑2).
• Fuel Compatibility: Certified for use with gasoline, diesel, ethanol blends, and biodiesel.

While the V10-72-1105 is designed for long life, regular maintenance of the fuel system can extend its service interval:

• Inspect fuel lines and filters annually to prevent contamination.
• Check for leaks around the sensor mounting area during routine inspections.
• Use high‑quality fuel additives that do not degrade sensor materials.

The Vemo V10-72-1105 Fuel Pressure Sensor delivers reliable, precise pressure monitoring essential for modern engine management systems. Its broad compatibility across the Volkswagen Group’s extensive lineup, combined with robust construction and advanced signal conditioning, makes it a superior choice for both OEM replacements and high‑performance aftermarket applications.
