EMS 4608

Blocks:

2098557, 2098556, 2110163, 2110160

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 4608 was registered and fault code 4352 was 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 4608 and DTC 4352 were registered, this may be due to the fact that the engine took a few turns in the opposite direction, for example, if the engine stalled while moving uphill.
If, when you try to start the engine, fault codes 4608 and 4352 are generated, this may be due to the fact that the crankshaft speed sensors of the engine were interchanged.

Notes:

If DTC 4608 was registered and DTC 4352 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.

EMS 4609

Blocks:

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:

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 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, protection against engine revs

Fault:

The crankshaft speed was above 2750 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:

As long as the DTC is present, the engine power is reduced.

Elimination:

Turn off and turn on the ignition with the ignition key to restart the engine control unit. If the elements have not been damaged when the allowed speed is exceeded, the engine will work normally again. Notify the driver about the possibility of engine damage when the engine is running at high speeds.

Fault:

Too fast increase of current in the coil of the solenoid valve pump-nozzle.

The reasons:

The fault may be due to a too low resistance of the solenoid valve.
If fault code 4643 was generated at the same time, it is possible that this is a consequence of a short circuit in the solenoid valve or electrical wiring. In addition, it is possible that a short circuit has occurred between the valve cover and one of the terminals on the solenoid valve.

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%.

Elimination:

Check the electrical components, electrical connectors and wiring.
Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.
Clear the trouble code memory.
If there is a malfunction, replace the injector pump first and then the control unit.

Title:

Fuel shutoff valve

Fault:

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:

Fuel shut-off valve stuck open.
If a malfunction code 4752 or 4753 was also generated, there may be a short circuit in the electrical circuit. Otherwise, either the fuel shut-off valve or the fuel supply pressure sensor is faulty.
Malfunction in the electrical circuit of the charge air pressure sensor, charge air temperature sensor, coolant temperature sensor or fan speed sensor.
Since the DTC is generated when the engine is turned off, it can only be deleted after the engine has been successfully turned off.

Notes:

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.

Elimination:

Check whether DTC 4752 or 4753 was generated. If so, check the fuel shut-off valve and the wiring.
If DTC 4752 or 4753 was not generated, first replace the fuel shut-off valve and then, if necessary, the pressure sensor in the fuel line.
Check the fuel line pressure sensor, coolant temperature sensor, charge air pressure sensor, charge air temperature sensor and fan speed sensor along with connectors and electrical wires of electrical circuits.

Title:

Fuel supply to cylinders

Fault:

The torque developed by the front group of cylinders (cylinders 1-3) significantly exceeds the torque developed by the rear group of cylinders (cylinders 4-6).

The reasons:

One of the fuel control or solenoid injection timing solenoid valves does not work correctly. In this case, the torque developed by one of the two groups of cylinders does not correspond to the specified value. This may be due to the fact that an excess amount of fuel enters the front group cylinders or too little fuel enters the rear group cylinders.
If the engine is gaining momentum, the front-group cylinder fuel control solenoid valve is stuck in a position where too much fuel flows into the cylinders.
If the engine is slowing down, the rear cylinder fuel control solenoid valve is stuck in a position where there is too little fuel in the cylinders.
If the engine drops speed and white smoke appears with the exhaust gases, then the solenoid valve controlling the injection timing of the rear group of cylinders lets in insufficient amount of fuel. Fuel injection starts so late that the fuel cannot ignite.
A malfunction may also be caused by leakage of the sealing rings on the pump nozzles.

Notes:

Uneven engine performance due to engine speed limiting at 500 … 550 rpm. The fuel shut-off solenoid valve is faulty.

Elimination:

If the engine starts to gain momentum, then replace the front cylinder group fuel control solenoid valve.
If the engine slows down, replace the rear cylinder fuel control solenoid valve.
If the engine has lost momentum and white smoke has appeared with the exhaust gases, then replace the solenoid valve controlling the advance angle of injection of the rear group of cylinders.
If you suspect a leak in the pump nozzles, replace all o-rings.

Title:

Control unit parameter

Fault:

In the engine control unit there is a parameter that indicates whether there is a clutch on the car.

The engine control unit also receives information about the status of the clutch from the coordinator on the CAN bus.

This DTC is generated if the setting in the engine control unit does not fully match the information that is received via the CAN bus.

The reasons:

A car can be converted without properly adapting the engine control unit, coordinator and SOPS file.
The engine control unit or coordinator could be replaced without proper programming of spare parts.

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 4881 was registered and fault code 4865 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 fault code 4881 and fault code 4865 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 4881 and 4865 are generated, this may be due to the fact that the engine speed sensors were interchanged.

Notes:

Title:

Crankshaft speed signals

Fault:

The signal level from the crankshaft speed sensor 2 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.
