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.

Fuel pressure sensor

Fault:

The voltage in the circuit exceeded the permissible level.

The reasons:

Possible reasons:

  • An open in the sensor circuit.
  • A fault can also be caused by a fault in other sensors with a common power supply circuit. If, at the same time, the memory code of the oil pressure sensor is recorded in the memory, a defect in the common internal power supply is possible.
  • Malfunction in the electrical circuit of the charge air pressure sensor, charge air temperature sensor, coolant temperature sensor or fan speed sensor.

Notes:

The coolant temperature sensor, the charge air pressure 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.

If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value.

With this fault, the engine torque is reduced by approximately 30% while the fault code is active.

Elimination:

Check the coolant temperature sensor, charge-air pressure sensor, charge-air temperature sensor, fuel line pressure sensor and fan speed sensor along with connectors and electrical wires of electrical circuits.

Pressure in the fuel supply system

Fault:

The pressure in the fuel line significantly exceeds the set value.

The reasons:

The probable cause of the malfunction is a defect in the bypass valve. It is also possible that the drain line is clogged.

Notes:

A fault code will be recorded only if the pressure in the fuel line exceeds the set value for 7 seconds or a longer time interval. This time period was set to avoid writing code due to short-term pressure fluctuations not caused by functional deviation.

If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value.

With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed). As a result of this malfunction, uneven engine operation and increased smoke can occur.

Elimination:

  1. Check the electrical components, electrical connectors and wiring.
  2. Check the bypass valve and fuel return line.

Blocks:

2110163, 2110160

Title:

Pressure in the fuel supply system

Fault:

The pressure in the fuel line is well below the set value.

The reasons:

Possible causes of failure:

  • One of the two relief valves opens at too low a pressure.
  • The fuel shut-off solenoid valve remains closed.
  • The fuel filter is clogged.
  • Air in the fuel or lack of fuel in the tank.
  • Malfunctioning booster pump.
  • Significant fuel leak from the system.

Notes:

A fault code will only be generated if the supply pressure is below the allowable pressure for at least 7 seconds. This time period was set to avoid writing code due to short-term pressure fluctuations not caused by functional deviation.

If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value.

With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed).

Elimination:

  1. Check for fuel in the tank and bleed the fuel system to remove air from it.
  2. Check the opening pressure of both relief valves.
  3. Check the position of the fuel shut-off solenoid valve.
  4. Check the condition of the fuel filter.
  5. Check the fuel priming pump.
  6. Check the tightness of the fuel system.
  7. If a malfunction has appeared while the car is coasting (when the car is going to descend with the accelerator pedal fully released), then you can use the “Stored operational data” engine parameters stored in the memory to analyze the fault. See “Feed Pressure” section. If the pressure deviation in the fuel line for a specified time interval is -1.0 bar or more, then the fuel filter may be clogged. If there is no significant pressure deviation in the fuel line, then this may be due to jamming of the bypass valve in the open position.

Title:

Pressure in the fuel supply system

Fault:

Feed pressure for a period exceeding the allowable value.

The reasons:

Possible reasons:

  • The pressure sensor in the fuel line shows incorrect values.
  • Bypass valve malfunction.

Notes:

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.

The oil pressure sensor, fuel temperature sensor and mass flow 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:

Fuel shut-off valve stuck open.

If a malfunction code of 55040 or 55041 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.

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.

The fault code is generated only in the case of three consecutive failed attempts to shut down.

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.

Please note that the oil pressure sensor, fuel temperature sensor and mass flow 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.

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:

A malfunction may be due to a failure of one of the fuel supply solenoid valves or an injection advance, which causes an incorrect engine torque for one row of cylinders. This may be due to the following reasons:

  • One of the front row solenoid valves of the cylinders supplying too much fuel (too high torque) to cylinders 1-3.
  • One of the solenoid valves in the rear row of cylinders that supplies too little fuel (too low torque) to cylinders 4-6.
  • If the engine produces a higher power than usual, immediately before the malfunction code is generated, one of the front row solenoid valves may be faulty.
  • If the engine produces a lower power than usual, immediately before the malfunction code is generated, one of the solenoid valves in the back row of cylinders may be faulty.
  • A fault code can also be generated even if there is no fault in any of the solenoid valves. In some cases, the DTC is caused by faulty pump injectors or fluctuations in the transmission caused by driving conditions.

Notes:

Engine may operate unevenly.

To protect the engine, the maximum engine torque is reduced by 30%.

To generate a DTC, the fault must be present for 6 seconds. If the fault disappears, after three seconds the engine will return to normal operation.

Elimination:

  1. To determine whether one of the solenoid valves causes a malfunction, proceed as follows : Switch the solenoid valves so that both the front row solenoid valves are responsible for the rear row and vice versa. Perform a road test car. Attach a load to the engine by performing a full load ride.
  2. If fault code 57090 has now been generated, one of the solenoid valves is a possible cause. Replace solenoid valves on the same row of cylinders. Clear the trouble code memory. Perform a road test car.Attach a load to the engine by performing a full load ride.
  3. If the fault persists, replace the solenoid valves on another row of 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 for controlling the injection timing of the rear cylinder group lets in insufficient amount of fuel. Fuel injection starts so late that the fuel can not be ignited.
  • 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:

Fuel supply to cylinders

Fault:

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

The reasons:

A malfunction may be due to a failure of one of the fuel supply solenoid valves or an injection advance, which causes an incorrect engine torque for one row of cylinders. This may be due to the following reasons:

  • One of the solenoid valves in the rear row of cylinders that supplies too much fuel (too high torque) to cylinders 4-6.
  • One of the front-row solenoid valves of the cylinders supplying too little fuel (too low torque) to cylinders 1-3.
  • If the engine produces a higher power than usual, immediately before the malfunction code is generated, one of the solenoid valves in the back row of cylinders may be faulty.
  • If the engine produces a lower power than usual, immediately before the malfunction code is generated, one of the front row solenoid valves may be faulty.
  • A fault code can also be generated even if there is no fault in any of the solenoid valves. In some cases, the DTC is caused by faulty pump injectors or fluctuations in the transmission caused by driving conditions.

Notes:

Engine may operate unevenly.

To protect the engine, the maximum engine torque is reduced by 30%.

To generate a DTC, the fault must be present for 6 seconds. If the fault disappears, after three seconds the engine will return to normal operation.

Elimination:

  1. To determine whether one of the solenoid valves causes a malfunction, proceed as follows : Switch the solenoid valves so that both the front row solenoid valves are responsible for the rear row and vice versa. Perform a road test car. Attach a load to the engine by performing a full load ride.
  2. If fault code 57088 has now been generated, one of the solenoid valves is a possible cause. Replace solenoid valves on the same row of cylinders. Clear the trouble code memory. Perform a road test car. Attach a load to the engine by performing a full load ride.
  3. If the fault persists, replace the solenoid valves on another row of cylinders.
  4. To see if there is something wrong with one of the pump injectors, look at the cylinder balance in the Scania Diagnos program .

Title:

Fuel supply to cylinders

Fault:

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

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 too little fuel flows into the front group cylinders or an excess amount of fuel flows into the rear group cylinders.
  • If the engine is gaining momentum, the rear cylinder fuel control solenoid valve is stuck in a position where there is too much fuel in the cylinders.
  • If the engine is slowing down, the front cylinder group 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 advance injection angle of the front group of cylinders lets in insufficient amount of fuel. Fuel injection starts so late that the fuel cannot ignite.

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 rear cylinder fuel control solenoid valve.
  2. If the engine slows down, then replace the front cylinder group 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 injection angle of the front cylinder group.

With an active fault code, the engine cannot be started. The starter is blocked and the fuel supply is turned off.

Elimination:

  1. Perform diagnostics using the coordinator. If there is no fault code in the memory of the coordinating unit, and the driver did not notice engine failures, then simply erase the fault code from the memory.
  2. Clear the DTC from the engine control unit. Ensure that this error code is no longer generated during operation.

Title:

Mutual verification between the engine control unit and the coordinator

Fault:

Mutual verification between the engine control unit and the coordinator failed.

The reasons:

The engine control unit is not associated with the coordinator.

Notes:

As long as the DTC is present, the engine cannot be started. The starter is blocked and the fuel supply is turned off.

Elimination:

  1. It is only necessary to delete the fault code if no fault codes were generated in the coordinator and the driver did not notice any faults. If any trouble codes are recorded in the coordinator’s memory, start troubleshooting.
  2. After completing the troubleshooting, erase the trouble code from the engine control unit. Ensure that this error code is no longer generated during operation.
