URO 03C906051A Fuel Injection Pressure Sensor

Fuel Pressure Sensor Overview

This URO fuel injection pressure sensor, part number 03C906051A, is built for direct-fit applications in Volkswagen and Audi fuel systems. It uses a 3-pin, female oval connector and an M6-1.0 thread for a secure sensor connection.

Fits confirmed applications including Volkswagen Passat, Touareg, and CC, plus Audi A8 Quattro and Q7 listings. The 03C906051A reference is also useful when matching replacement sensors by OE number.

Key Features

• Fuel injection pressure sensor for air and fuel delivery systems
• Maximum pressure reading of 625 for pressure monitoring applications
• 3-terminal pin design with female oval connector
• M6-1.0 thread diameter for specified mounting points
• Mounting hardware not included

Detailed Fitment and Function

Part number 03C906051A is used to monitor fuel pressure in applications that require accurate pressure feedback from the supply line or high-pressure fuel pump area. It fits 2006-2008 Volkswagen Passat, at high pressure fuel pump; 2007-2010 Audi Q7, on supply line; 2007-2017 Volkswagen Touareg, on supply line; 2009-2016 Volkswagen CC, on supply line; 2012-2013 Audi A8 Quattro, on supply line; 2012-2014 Volkswagen Passat, on supply line; and 2016-2018 Volkswagen Passat, N/A. This sensor is a practical replacement when the original unit is no longer reading pressure correctly or the connector and thread specification must match the factory setup. The 03C906051A part number should be verified against the existing sensor before installation.

Common Issues It May Address

• Fuel pressure signal errors
• Hard starting related to incorrect pressure readings
• Driveability problems from unstable fuel delivery data
• Check engine light conditions tied to pressure sensor faults
• Replacement needs for damaged connector or threaded sensor body

Installation Notes and Quality

Confirm connector shape, terminal count, and thread size before installation. This sensor uses a female oval connector with three male terminals and does not include mounting hardware. Verify the application against the vehicle’s original part number and fuel system layout to ensure proper fitment.
