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.

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).

  • The engine speed sensor produces an incorrect signal.
  • This DTC may occur when the engine is started at a very low temperature or when the battery is low.

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:

  1. Check sensors, connectors and wiring.
  2. Check battery voltage

Title:

Pump nozzle cylinder 5

Fault:

Too slow increase of current in the winding of the solenoid valve. The rise time of the current is determined by the control unit, depending on the voltage of the battery and the temperature of the coolant.

The reasons:

  • The fault may be due to too high resistance, the reason for which may be:
  • Open circuit between control unit and solenoid valve.
  • Damaged wiring.
  • Open circuit inside the control unit.

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. If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%.

Elimination:

  1. Check the electrical components, electrical connectors and wiring.
  2. 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.
  3. Clear the trouble code memory.
  4. If there is a malfunction, replace the injector pump first and then the control unit.

  • Malfunction in the electrical circuit of the charge air pressure sensor, charge air temperature sensor, coolant temperature sensor or fan speed sensor.

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.

During the entire time when the pressure in the fuel line exceeds the set value, the fuel shut-off solenoid valve is closed. If the fuel pressure sensor is faulty, then the fuel shut-off solenoid valve when the engine is running is constantly open.

Elimination:

  1. 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.
  2. Make sure the bypass valve opens.

Title:

Fuel shutoff valve

Fault:

High voltage is constantly applied to the outputs of the fuel shut-off solenoid valve.

The reasons:

Breakage of the fuel shut-off solenoid valve wiring or breakage of the valve winding. The cause of the fault may also be a short circuit to the wire connected to the positive terminal of the battery.

Notes:

If an open circuit occurs, the fuel cut-off solenoid valve closes and the engine stops.

In the event of a short circuit, the fuel shut-off solenoid valve will be constantly open.

Elimination:

Check the wiring and fuel shut-off solenoid valve.

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:

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.

Elimination:

  1. Check whether DTC 4752 or 4753 was generated. If so, check the fuel shut-off valve and the wiring.
  2. 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.
  3. 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:

  1. If the engine starts to gain momentum, then replace the front cylinder group fuel control solenoid valve.
  2. If the engine slows down, replace the rear cylinder fuel control solenoid valve.
  3. 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.
  4. If you suspect a leak in the pump nozzles, replace all o-rings.

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.

Fault:

When the engine is running, the signals from the two speed sensors do not match.

The reasons:

  • If fault code 4865 was registered, and fault code 4881 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 fault code 4865 and fault code 4881 were registered, this may be due to the fact that the engine took a few turns in the opposite direction. The fault code becomes inactive when the engine stops rotating in the opposite direction.
  • If when you try to start the engine, fault codes 4865 and 4881 are generated, this may be due to the fact that the crankshaft speed sensors of the engine were interchanged.
