Rail Pressure Sensor Tester - RA-1101

RA-1101 Rail Pressure Tester is designed to test Bosch rail pressure sensor for common rail diesel engines. RA-1101 can be used to monitor engine rail pressure and diagnose common rail diesel engine faults with no interference to engine ECU during engine running by the site of a fault vehicle. RA-1101 can test also rail pressure for a common rail fuel system on a fuel pump test bench independently. RA-1101 is able to detect the DC +5V power supply for the sensor and switch automatically the power supply source, for which the default is an external ECU +5V power supply and the alternative is the internal +5V power supply of the tester.

This tester is a powerful indispensable tool for repair technicians to diagnose common rail engine ECU, fuel system and rail sensor.

Design Features

Compact and easy to use

Able to test Bosch rail pressure sensors in 3 scales, 0-1500bar, 0-1800bar, and 0-2000bar

Able to measure fuel rail pressure in real-time and diagnose common rail diesel engine faults on site of faulty vehicles

Able to monitor rail pressure sensor without affecting diesel engine ECU rail pressure signal

Able to detect the source of +5V power supply for the rail pressure sensor, switch automatically to the power supply available and display the power supply source on its screen

Over-pressure warning

Battery low indication

A full set of accessories, harness, battery

The following common rail engine faults can be determined based on the test results by the RA-1101 Rail Pressure Tester

Whether the ECU +5V power supply is normal or not

Whether ECU rail pressure signal circuit is normal or not

Whether 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, low pressure circuit or high pressure pump
