• Fast response time for fuel system control feedback
• Wide measurement range for diesel engine applications
• Direct replacement for select 2004-2006 diesel trucks and SUV applications
• Cross-reference: 93185626 for the same application

Detailed Description

This Bosch diesel pressure sensor is engineered for vehicles that depend on accurate fuel rail pressure data to manage injection timing and engine operation. It is a direct-fit replacement for 2004-2005 Chevrolet Silverado 2500 HD, 2004-2005 Chevrolet Silverado 3500, 2004-2005 GMC Sierra 2500 HD, 2004-2005 GMC Sierra 3500, and 2005-2006 Jeep Liberty diesel applications, with 2004 coverage beginning from 06/2004 on the listed GM trucks. The Bosch 0281002937 supports consistent sensor output for diesel fuel delivery systems where rail pressure accuracy matters.

What It Helps Address

• Incorrect fuel rail pressure readings
• Diesel engine performance issues related to rail pressure signal loss
• Hard starting caused by inaccurate pressure feedback
• Fuel system fault codes tied to rail pressure sensor operation
• Unstable injection control from a worn or failing sensor

Installation Notes and Tips

Verify the part number and vehicle application before installation. Confirm the connector style, mounting location, and model-year coverage against the existing sensor on your Chevrolet Silverado 2500 HD, Silverado 3500, GMC Sierra 2500 HD, Sierra 3500, or Jeep Liberty diesel application. After installation, clear any stored diagnostic trouble codes and recheck fuel rail pressure data with a scan tool.
