• Monitors fuel rail pressure for engine management accuracy
• Direct-fit replacement for fuel injection fuel rail applications
• Fits multiple Buick, Cadillac, Chevrolet, and GMC models
• Part number 883-001 for easy identification

Detailed Description

GBR 883-001 is a fuel pressure sensor used on the fuel injection fuel rail to report pressure data to the engine control system. Accurate pressure feedback is important for stable idle quality, consistent starting, throttle response, and fuel economy. This part cross-references GM OE numbers 12633417 and 12635273 for the same application. Compatible vehicle coverage includes Buick Regal, Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Chevrolet Equinox, Chevrolet Impala, GMC Terrain, and related models listed in the fitment data. If you are replacing a failing sensor on a Buick Regal or Chevrolet Impala, part number 883-001 provides the correct application match for the listed vehicles.

Common Issues This Part May Address

• Rough or unstable idle
• Hard starting or extended crank time
• Hesitation during acceleration
• Reduced engine power response
• Lower fuel economy from inaccurate pressure readings

Installation Notes and Tips

Install this sensor at the fuel injection fuel rail location specified in the fitment notes. Verify the vehicle year, make, and model against the fitment table before ordering, since coverage varies by application. Confirm connector condition and inspect the fuel rail area for contamination or damage before installation.

Quality Assurance

GBR part number 883-001 is built as a replacement fuel pressure sensor for the listed GM applications. Use the fitment data to confirm the correct Buick, Cadillac, Chevrolet, or GMC application before installation.
