Title:
Crankshaft speed signals
Fault:
No signals from both crankshaft speed sensors.
The reasons:

A fault code can be set if the speed sensors are not connected at all, or both speed sensors are faulty.
The DTC can be set at start-up with a discharged battery.
Also, this fault may occur if the starter is not connected to the control unit, or if the output signal of the control unit for the starter is incorrect.

Notes:
Shutting off the fuel in the absence of a signal from one of the engine speed sensors.
Elimination:

If the engine crankshaft rotates when the starter is activated, check the speed sensors, connectors and wiring.

Title:
Crankshaft speed signals
Fault:
When the engine is running, the signals from the two speed sensors do not match.
The reasons:

If fault code 4352 was registered and fault code 4608 is not, this may be due to the fact that the electrical wiring going to one of the engine crankshaft speed sensors is confused. The control unit cannot determine which.
If, however, both DTC 4352 and DTC 4608 were registered, this may be due to the fact that the engine took a few turns in the opposite direction.
If, when you try to start the engine, fault codes 4352 and 4608 are generated, this may be due to the fact that the engine speed sensors were interchanged.

Notes:
If DTC 4352 was registered and DTC 4608 is not, as long as a fault is present, the maximum engine torque is reduced by 30%. Increased engine speed at idle will also be lower than usual.
If both crankshaft speed sensors are faulty, the engine will shut down.
Elimination:
Check sensors, connectors and wiring.

Title:
Fuel pressure in the accumulator
Fault:
The fuel pressure in the pressure accumulator exceeded the maximum permissible value.
The reasons:

Possible reasons:
Feed pressure too high.
Fuel metering inlet valve sticking or leaking.
Faulty diffuser in high pressure pump.

Notes:
At low loads, abnormally high noise generated during combustion may be present.
As long as this DTC is active, the engine power is limited and the EGR system is deactivated.
The fault code cannot be cleared while the fault is present.
Elimination:

The pressure in the fuel system reaches a very high value, up to 3000 bar.
Before starting any work, release pressure in the fuel system. When handling the system, it should be assumed that it is under pressure, even if the engine is off.
Wear protective gloves and goggles.
Additional information about the rules of safe handling of the fuel system is given in the service instructions, section “Fuel System XPI”.
If there is any trouble code related to the fuel metering inlet valve, first replace it.
Then check the supply pressure as described in L6 of document 03: 14-01, edition 2. Continue with the Lc “troubleshooting tree” if the pressure is too high. Otherwise, replace the fuel metering inlet valve.
If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65.

Title:
Charge air pressure sensor
Fault:
The charge air pressure and atmospheric pressure differ when the engine is idling.
The reasons:

Possible reasons:
Malfunction of the charge air pressure sensor or atmospheric pressure sensor.
Malfunction of coolant temperature sensor, charge air temperature sensor, fuel line pressure sensor or fan speed sensor.
The fault may also be in the connectors or electrical wiring circuits.

Notes:
The charge air pressure sensor, the coolant temperature sensor, the charge air temperature sensor, the fuel line pressure 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.
Elimination:

Make sure that the charge air pressure and the atmospheric pressure are about the same value, approximately 1 bar of absolute pressure, with the engine off or when the engine is idling.
Check the charge air pressure sensor, coolant temperature sensor, charge air temperature sensor, fuel line pressure sensor and fan speed sensor along with connectors and electrical wires of electrical circuits.
Check whether the charge air pressure sensor is covered with soot. If so, clean it.
If a fault in the charge air pressure sensor is not detected, troubleshoot the atmospheric pressure sensor using a coordinator.

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:

A malfunction may be due to an excessively large distance between the engine speed sensor and the flywheel.
In addition, it may be due to a problem in the wiring or connectors.

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 greater than in the two cases, check the distance between the sensor and the flywheel (which is allowed a maximum of 1.5 mm).

The reasons may be as follows:
The presence of air in the fuel injection system, which may be caused by a low level of fuel in the tank or air leakage before the boost pump. If the reason lies in this, then a similar fault code can be written for several cylinders.
External leak nozzles or internal “overflows”.
HPI: A malfunction in the injector supply line or a malfunction of the injection timing control solenoid valve.
PDE: Faulty solenoid pump injector valve.
On HPI engines, this DTC can be generated if not all the fuel intended for it is injected into the cylinder. Then the next cylinder in this ignition sequence in the same row of cylinders will receive too much fuel, which the control unit is trying to reduce.

Notes:
As a result, the engine runs unevenly. If the cylinder receives too much fuel, it can lead to black smoke.
