2098557, 2098556, 2110163, 2110160
Title:
Crankshaft speed signals
Fault:
The speed signal from the engine crankshaft speed sensor is lower than it should be for the current crankshaft speed.
The reasons:
Notes:
The control unit increases the sensitivity of the sensor so that a fault code is not generated. Therefore, a fault code will not be generated again even if the fault still persists. This increase in sensor sensitivity may lead to the generation of other trouble codes. These DTCs can be ignored. The automatic adjustment performed by the control unit does not in any way affect the operation of the control unit.
The fault does not affect the operation of the engine, i.e. There is no power limit.
Elimination:
If the DTC was generated in more than two cases, check the distance between the sensor and the flywheel (a maximum of 1.5 mm is allowed).

Title:
Engine speed, protection against engine revs
Fault:
The crankshaft speed was above 2900 rpm.
The reasons:
Operator error, for example, improper downshifting
A malfunction can also be caused by oil leaking from the turbocharger into the air intake system or fuel leaking from one of the injectors into the cylinders.
Notes:
The engine brake is activated and brakes the engine with maximum efficiency. The fault remains active until the engine speed drops below 2500 rpm.
Elimination:
If there are no faulty elements after the engine speed is reduced, the engine is working normally. Notify the driver about the possibility of engine damage when the engine is running at high speeds.

Title:
Engine speed sensor 2
Fault:
The engine speed determined by the signal from the speed sensor is below the set minimum value.
The reasons:
Open circuit engine speed sensor. This DTC may occur when the engine is started at a very low temperature or when the battery is low.
Notes:
If a malfunction code of 4615 was simultaneously generated, it is possible that the signal was absent for several engine revolutions, otherwise the malfunction is due to temporary noise.
If only one of the crankshaft speed sensors is faulty, as long as the fault is present, the maximum engine torque is reduced by 30%. Increased engine speed at idle will also be lower than usual.

Too fast increase of current in the coil of the solenoid valve pump-nozzle.
The reasons:
Notes:
The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.
If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%.

When the engine is stopped by turning off the fuel shut off valve, the fuel pressure in the low pressure line drops very slowly.
The reasons:
Possible reasons:
Notes:
The pressure sensor in the fuel line, the coolant temperature sensor, the charge air pressure sensor, the charge air temperature sensor and the fan speed sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors.
When the engine is turned off with the ignition key, the solenoid valves will continue to try to keep the engine running, while the fuel shut-off solenoid valve sends a signal to turn off the engine. If this fails, i.e. the pressure in the fuel line will not decrease, a malfunction code is generated, after which the engine is turned off by the electromagnetic valves.
A fault code is generated only in the case of three consecutive failed attempts to turn off the engine.
While the fault is active, the maximum engine torque is reduced by 30%.
Since the DTC is generated when the engine is turned off, it can only be deleted after the engine has been successfully turned off.
