A fuel rail pressure sensor measures the pressure of fuel in the fuel rail and sends this information to the engine control unit (ECU). The ECU uses this data to adjust fuel delivery for optimal engine performance, efficiency, and emissions.
Common symptoms include a check engine light with related diagnostic trouble codes (DTCs), rough idling, stalling, poor acceleration, or difficulty starting the engine.
This Bosch sensor (0 261 545 055) is compatible with vehicles that use specific OEM part numbers, including GMC12618108, OPEL0815155, 12618108, 12618608, SAAB12618108, and VAUXHALL12618108. Always verify your vehicle's original part number.
Installation involves working with the fuel system, which can be dangerous if not done correctly. It is highly recommended to have a qualified professional mechanic perform the installation.
Warranty information can vary. Please refer to the retailer or manufacturer's documentation for specific warranty details pertaining to this product.
Bosch is a leading automotive parts manufacturer known for quality and reliability. Using a Bosch sensor ensures it meets high standards for accuracy, durability, and performance, often matching or exceeding OEM specifications.
Verify the sensor is correctly installed and connected. Inspect wiring for damage. If the sensor is functioning correctly and wiring is intact, the sensor may need replacement.
Ensure the fuel pressure sensor is properly seated and the electrical connector is secure. Check for fuel leaks around the sensor. If no leaks are found, the sensor may be providing inaccurate readings and could require replacement.
Confirm the sensor is compatible with your vehicle and correctly installed. A faulty sensor can cause the ECU to miscalculate fuel delivery, impacting performance. Consult diagnostic codes for specific indications.
Check the electrical connection to the sensor. A disconnected or faulty sensor can prevent the ECU from enabling fuel injection. Verify fuel pump operation and other relevant fuel system components.
Compatibility:
This sensor is designed to be a direct replacement for specific OEM part numbers. Always verify that your vehicle's existing part number matches one of the compatible OEM references: GMC12618108, OPEL0815155, 12618108, 12618608, SAAB12618108, and VAUXHALL12618108. It is fitted in vehicles such as the OPEL ASTRA J Coupe 2.0 OPC Turbo, OPEL INSIGNIA A (G09) 2.0 E85 Turbo, and OPEL INSIGNIA A (G09) 2.0 Turbo.
Setup and Installation:
Installation of a fuel pressure sensor involves working with the vehicle's fuel system. It is strongly recommended that installation be performed by a qualified mechanic. The process typically involves:
Care:
Fuel pressure sensors are sealed electronic components and do not require routine user maintenance. Keep the sensor and its electrical connector clean and free from contaminants like dirt, oil, or excessive moisture. Avoid using harsh solvents on or near the sensor. Any signs of physical damage or corrosion on the connector should be addressed immediately during inspection.
