Title:

EGR valve with a pneumatic cylinder control

Fault:

When an EGR valve receives a request to go to the open position, the EGR valve position sensor T124 indicates a position close to closed.

The reasons:

Possible reasons:

The EGR valve is locked in the closed position or jammed due to mechanical failure or corrosion.

Fault in the cylinder control valve EGR.

The EGR valve cannot open due to a leak in the compressed air pipeline leading to the EGR valve control cylinder.

Malfunction in the air supply to the valve block or malfunction in the valve block, V107.

The EGR Position Sensor T124 is faulty or disconnected from the circuit.

Notes:

After starting the engine, the engine control unit performs an active check on the EGR valve if the following conditions are met:

The engine runs at idle.

Engine temperature above 60 ° C.

There is no request to turn on the EGR system (0%).

Motor brake is not included.

EGR has been adapted.

The air pressure in the parking brake circuit is at a normal level (above 7.5 bar).

In the event of a fault, the engine control unit shuts off the EGR system and the engine power decreases.

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

Elimination:

Check:

EGR valve control cylinder by activating the EGR valve using SDP3.

EGR valve for movement without sticking.

The EGR valve control cylinder, connectors and wiring to the T124 position sensor circuit.

The air supply to the control cylinder and valve block V107.

If the EGR valve position sensor T124 is faulty or disconnected from the circuit.

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.

Be sure to perform basic adjustment and adaptation of the EGR system using SDP3 after corrective actions in the EGR system.

Malfunction adversely affects engine emissions of nitric oxide.

On vehicles with NOx, the warning lamp comes on and the maximum torque is limited to 40%. The fault code cannot be cleared while the fault is present. To become inactive, it requires confirmation from the system.

Elimination:

Check the exhaust gas temperature sensor and its connectors and wiring.

The temperature sensor in front of the catalytic converter SCR is faulty.

Notes:

A malfunction leads to a lack of reagent supply or the addition of a very small amount of reagent.

An active DTC limits the maximum engine torque to approximately 40%.

An active DTC cannot be deleted from the control unit. When the malfunction is resolved so that the malfunction code becomes inactive, the control unit must ensure that the malfunction has been eliminated.

Elimination:

Check exhaust gas temperature sensor and wiring.

Use the following options to ensure that the problem is resolved:

To verify that the malfunction has been rectified, perform the “Recognizing DTCs for NOx Control Invalidations” check, which is located on the “Checks” tab in SDP3. This test should be performed outdoors, because the exhaust gas temperature becomes very high and there is a risk that the exhaust hose will melt. Performing this check may take from 5 to 30 minutes, depending on which DTCs are active.

Otherwise, follow these steps to make the control unit invalidate the fault.

Start the engine and verify that the engine speed is above 1000 rpm and that the SCR system starts. Repeat this four times in a row. If the temperature is below -8 ° C or the reagent is frozen, the SCR system will not start.

If the fault is resolved, the fault code becomes inactive. Clear the fault code.

You can go to the fault code monitoring function and view the fault code. There you can see if the conditions under which the control unit confirms that the fault has been eliminated have been satisfied. When conditions are satisfied and a check is performed, the status of the DTC is displayed during the check process. If the DTC is under review, the control unit has detected a fault. If the fault is resolved, the fault code becomes inactive and can be erased.

Using the ignition key, turn off and turn on the power three times in a row at intervals of 10 seconds to deactivate the test lamp.

Title:

Starter.

Fault:

The starter is not activated during the start attempt.

The reasons:

Open in the magnetic coil of the starter.

Notes:

The starter is not activated during the start attempt.

Elimination:

Check the electromagnetic coil, as well as the elements of the electrical circuit, electrical connectors and electrical wiring.

Title:

Oil pressure sensor

Fault:

One or more faults in the oil pressure sensor.

The reasons:

The malfunction is caused by the fact that several different malfunctions occur simultaneously in the element.

Notes:

Possibly incorrect value from the oil pressure sensor.

Elimination:

Perform a general troubleshooting procedure for this item. Check the electrical components, electrical connectors and wiring. If other trouble codes are generated, first troubleshoot them.

Title:

Oil pressure sensor

Fault:

The voltage in the electrical circuit was below normal.

The reasons:

A short to ground or open circuit in the output signal or battery voltage.

Notes:

The instrument panel shows no oil pressure, regardless of whether there is sufficient oil pressure.

Low oil pressure warning light is off.

Elimination:

Check the oil pressure sensor, electrical connectors and wiring.

Blocks:

2110164, 2110165, 2110166, 2110162, 2110116

Title:

Oil pressure sensor

Fault:

The voltage in the circuit has fallen below acceptable levels.

The reasons:

Possible reasons:

Short circuit in the oil pressure sensor circuit.

Malfunction of the electrical circuit of the fuel temperature sensor or electrical circuit of the mass flow sensor.

Notes:

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.

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

The oil pressure gauge on the instrument panel shows 0 bar regardless of engine speed. The warning lamp for emergency oil pressure does not turn on.

Elimination:

Check the oil pressure sensor, fuel temperature sensor and mass flow sensor with connectors and electrical wiring.

Title:

Oil pressure sensor

Fault:

The voltage in the electrical circuit was above normal.

The reasons:

Short to battery or lost ground.

Notes:

The instrument panel shows no oil pressure, regardless of whether there is sufficient oil pressure.

Low oil pressure warning light is off.

Elimination:

Check the oil pressure sensor, electrical connectors and wiring.
