GBR 881-001 Fuel Pressure Sensor

Fuel Pressure Sensor Overview

The GBR Fuel Pressure Sensor, part number 881-001, is a direct replacement sensor for vehicles that rely on accurate fuel rail pressure readings. When the sensor signal becomes inaccurate, drivability issues can follow, including rough idle, hard starting, hesitation, and reduced fuel economy.

Key Features

• Fuel pressure sensor for air and fuel delivery systems
• Direct replacement application for select Jeep, Dodge, and Alfa Romeo models
• Supports accurate fuel pressure monitoring for consistent engine operation
• Part number 881-001 for easy identification
• This part cross-references 68445162AA and 68445162AB for the same application.

Detailed Description

GBR 881-001 is a fuel pressure sensor used to monitor fuel rail pressure and send the signal needed for proper engine management. It is listed for the 2025 Alfa Romeo Tonale, 2023-2025 Dodge Hornet, 2023-2025 Jeep Compass, 2022-2025 Jeep Grand Cherokee, and 2022-2025 Jeep Wrangler. On the Jeep Grand Cherokee application, the sensor is located on the fuel rail. If the original sensor is failing, this replacement can restore more stable fuel system readings and help address symptoms tied to incorrect pressure data. The part number 881-001 is also referenced by 68445162AA and 68445162AB.

What It Is Used For

• Rough idle caused by incorrect fuel pressure readings
• Hard starting related to fuel system signal errors
• Hesitation during acceleration from unstable pressure data
• Reduced engine power linked to inaccurate sensor output
• Poor fuel economy associated with faulty fuel pressure monitoring

Installation Notes and Tips

Verify the vehicle application by year, make, and model before ordering. Confirm the sensor location on the fuel rail where applicable, and compare the connector and mounting style to the original part. Use the part number 881-001 and the listed interchange numbers to confirm the correct replacement.

Quality Assurance

GBR identifies this as a fuel pressure sensor replacement for select late-model applications. Confirm fitment against the vehicle listing and original part number before installation.
