Rail Pressure Tester

The most comprehensive and efficient rail pressure portable testing instruments !

RA-2000 Rail Pressure Diagnoser is the updated design to test rail pressure sensors by Bosch, Denso and Delphi for common rail diesel engines. RA-2000 can be used to diagnose common rail diesel engine faults with no interference to engine ECU during engine running on the site of a fault vehicle.There will be no longer any need to use a troublesome mechanical gauge to monitor rail pressure.

This instrument is a powerful indispensable tool for technicians to diagnose ECU, fuel system and rail pressure sensor for a common rail engine with problems, such as difficult to start engine or lack of power.

Design Features:

•  Compact and easy to use
• Test common rail pressure sensors made by
  • Bosch, in 4 scales, 0-1500bar, 0-1800bar, 0-2000bar and 0-2800bar
  • Denso, 0-2000bar
  • Delphi, 0-2000bar

• Rail pressure sensor signal feeds to both RA-2000 and engine ECU. 
  • Real time pressure measurement
  • No affecting engine ECU operation.  
• Monitor engine ECU +5V power supply for pressure sensor
• Over-pressure warning
• Powered by 9VDC battery
• Battery low indication
• A full set of accessories, including harnesses for Bosch, Denso, Delphi sensors, and battery

The following common rail engine faults can be determined based on the test results by the RA-2000 Rail Pressure Diagnoser

• Whether the ECU +5V power supply is normal or not
• Whether the rail pressure signal circuit in ECU is normal or not
• Whether the rail pressure sensor has fault or not
• No sufficient rail pressure during the engine starts is an indication of faults on the engine fuel system, especially low pressure circuit or high pressure pump
