Title:

SCR – Nitrogen oxides (NOx) after catalytic converter

Fault:

The measured amount of nitrogen oxides is different from what should be.

The reasons:

  • The control unit detects that the SCR system incorrectly reduces the amount of nitrogen oxides.
  • This may be due to a malfunctioning catalytic converter, a malfunctioning NOx sensor, or a malfunctioning reagent dosing system.
  • The calculated NOx is different from the measured NOx. The reason for this may be an excessively high or variable amount of NOx from the engine or an incorrect value from the NOx sensor.

Notes:

The fault affects the emission of nitrogen oxides (NOx) by the car, and a warning lamp lights up in the instrument cluster, warning of a high level of pollutants.

Elimination:

  1. Check for any other trouble codes related to exhaust emissions.
  2. Make sure that the reagent tank contains an AdBlue reagent.
  3. Ensure that the reagent lines and injection device are not plugged. The crystals can be washed off with water.
  4. Make sure the reagent dispenser is not blocked. The crystals can be washed off with water.
  5. Check the NOx sensor.
  6. Check that the catalytic converter is intact.
  7.

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:

  1. The pressure in the fuel system reaches a very high value, up to 3000 bar.
  2. 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.
  3. Wear protective gloves and goggles.
  4. Additional information about the rules of safe handling of the fuel system is given in the service instructions, section “Fuel System XPI”.
  5. If there is any trouble code related to the fuel metering inlet valve, first replace it.
  6. 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.
  7. 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:

  1. 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.
  2. 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.
  3. Check whether the charge air pressure sensor is covered with soot. If so, clean it.
  4. 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).

Fault:

The lowest value has been reached to which the control unit can adjust the amount of fuel for the cylinder

The reasons:

  • The power generated by the cylinder, more than in other cylinders.
  • 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.

  • The power generated by the cylinder, more than in other cylinders.
  • 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.

Elimination:

  1. Remove air from the fuel system.
  2. Verify that there are no leaks in the supply line.
  3. If malfunctions occur again:
  4. Check the pump injectors.
  5. HPI: Check the fuel solenoid and injection advance solenoid valves.
  6. PDE: Check the solenoid valve on the injector pump problem.
  7. To check if the malfunction has been fixed and if the malfunction code does not occur again, you can click on the malfunction code monitoring function and view the malfunction code. This DTC is not generated immediately. In order for the control unit to generate an active fault code, the control unit must complete the test within 4×15 minutes with negative results. This means that the engine must be started and must idle for 15 minutes four times in a row. To see if the DTC is in the process of reviewing, that is, if a DTC is generated before it becomes active, you can use the DTC monitoring feature.

Title:

Pump nozzle cylinder 1

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 4627 was generated at the same time, it is possible that this is a consequence of a short circuit in the solenoid valve or the 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:

  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.

Title:

Failed mass flow sensor adaptation

Fault:

The engine control unit calculates that more air enters the engine than is measured by the T126 mass flow sensor.

During the adaptation of the mass flow sensor, the highest possible permissible value is obtained, which can be adapted at one operating point.

The reasons:

Possible causes of a malfunction can be the following:

  • leaks in the EGR system or in the charge air system
  • mass flow sensor T126 gives incorrect readings
  • wrong values ​​from the back pressure sensor in the exhaust system T125, charge air pressure sensor T122 or charge air temperature sensor T121

Notes:

The engine control unit uses information from the mass flow sensor to regulate the EGR content and to calculate the ratio of air and fuel. The calculation is also performed taking into account the engine speed, the amount of fuel injected and the signals from the backpressure sensor in the exhaust system, the charge air pressure sensor and the charge air temperature sensor. The calculated amount of air is compared with the signal from the mass flow sensor at certain predetermined engine speeds (operating points). The adaptation of the mass flow sensor is performed in such a way that the calculated value coincides with the measured value at these engine speeds. Adaptation occurs continuously throughout the work. During adaptation, the EGR valve closes temporarily. Adaptation occurs every hour.

If there is a leak in the EGR system or the charge-air system, or in the event of a failure of any of the sensors, the adaptation of the mass flow sensor may fail. If the difference between the calculated and measured mass flow rate is more than 30%, the adaptation will reach its minimum or maximum allowable value and a fault code will be generated.

The engine control unit turns off the EGR system and the engine power decreases.

The fault code cannot be cleared while the fault is present.

Elimination:

  1. Check for leaks in the EGR system or in the charge-air system. Perform an “EGR check for leaks” in SDP3, if available.
  2. Check the mass flow sensor T126, the back pressure sensor in the exhaust system T125, the charge pressure sensor T122 or the charge temperature sensor T121.
  3. Check the connectors and electrical wiring.
  4. After diagnostics and repair, always perform the “EGR check for invalidation of malfunction codes” if this malfunction code has been generated. This check can be performed using SDP3.
  5. If the DTC persists after checking, it is likely that the repair was performed incorrectly or the software in the engine control unit is out of date. With SDP3 / VERA, make sure the car engine software is updated to the latest version. If the software is old, program the EMS as a spare part.
  6. 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.
