The Cummins 6ISBe engine is a 4-stroke diesel engine with 6 cylinders in a row, which is a rather unusual design solution for engines of this class. It is considered the quietest engine in the series.
Thanks to the improved Common Rail fuel system, the fuel injection pressure is independent of the engine speed. This improves ride performance, reduces noise and improves cold start. Also, thanks to this system, Cummins 6ISBe consumes less diesel fuel compared to analogues. The presence of a turbocharger significantly improves engine performance, increases power with economical fuel consumption.
In a number of design and technological solutions, 6ISBe is similar to the previous generation Cummins B-series engines. The letter “e” in the designation indicates that it is designed for Europe.
The cylinder block is a single cast structure, there are no liners, this is what affects the durability and comfort during operation. To increase the performance parameters, a VGT turbocharger is installed, which, in addition to the main function, contributes to fuel economy when operating at full power.

Error codes Cummins 4ISBe
- 111 – Internal failure of the ECM. This DTC can only occur if there is a problem inside the ECM. The ECM cannot be repaired.
- 115 – Malfunction of the camshaft position sensor. The ECM detects that the signal inputs of the crankshaft position and camshaft position sensors are reversed.
- 122 – Malfunction of the turbine pressure sensor. The ECM determines that the intake manifold pressure sensor signal voltage has been greater than the calibrated value for more than 1 second.
- 123 – Intake manifold pressure sensor circuit – voltage below normal or short circuit. The ECM determines that the intake manifold pressure sensor signal voltage is less than the calibrated value for more than 1 second.
- 124 – High pressure in the intake manifold. This DTC becomes active when the intake manifold pressure exceeds the maximum allowable value for a given engine power rating.
- 131 – Malfunction of the gas pedal throttle. The ECM detects that the accelerator pedal position sensor signal voltage has been greater than the calibrated value for more than 1 second.
