Fault Code Register of Volvo TAD SeriesEngine

Fault Code Register of Volvo TAD SeriesEngine

To keep engine run well, it is not enough to know about the fault code, but also need to know the possible reasons and reaction, which can quickly solve the problems. In this part, we mainly talk about Volvo TAD Series generator engine fault code register.

Fault Code Register of Volvo TAD SeriesEngine

Fault Code Register

No faults (code 2.0.0)

Engine speed sensor, camshaft (code 2.1.1, PID190)

Possible reason:

• Faulty sensor, connector or cable.

• Incorrect distance to cam wheel.

• High frequency interference.

Reaction: Engine is shut off.

Action:

• Check that the engine speed sensor is installed with the correct distance to the camshaft.

• Check the cables for the engine speed sensor for breaks and short circuits.

• Check the connector for poor contact.

• Check sensor function. Change the sensor as necessary.

Overspeed (Code 2.1.4, PID190)

Possible reason: The engine speed is or has been higher than the permissible.

Reaction: Fuel injection ceases and the fault code lamp lights up until the engine speed falls below the permissible limit again.

Action:

• Check the control rod for the injection pumps.

• Check the actuator, replace it if necessary.

• Check the cables for the actuator for breaks and short circuits.

• Check the number of teeth on the camshaft wheel.

• For VE engines, it may be necessary to check the function of the “limp home” mode.

Accelerator pedal sensor (Code 2.2.1, PID 91)

Possible reason: Faulty sensor, connector or cable.

Reaction: Engine goes to limp home speed.

Action:

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

Charge pressure sensor (Code 2.2.2, PID 102)

Possible reason: Faulty sensor, connector or cable.

Reaction: A fault code is generated.

Action:

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

Oil pressure sensor (Code 2.2.4, PID 100)

Possible reason: Faulty sensor, connector or cable.

Reaction: A fault code is generated.

Action:

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

Coolant temperature sensor (Code 2.2.5, PID 110)

Possible reason: Faulty sensor, connector or cable.

Reaction: A fault code is generated.

Action:

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

Fuel temperature sensor (Code 2.2.7, PID 174)

Possible reason: Faulty sensor, connector or cable.

Reaction: A fault code is generated.

Action:

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

Emergency stop, oil pressure (Code 2.3.1, PID 100)

Possible reason: Engine oil pressure low. (The engine oil pressure is depended by the engine revolution.)

Reaction: Engine is emergency stopped.

Action:

• Check the oil level and oil pump.

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

• Check the limit value for engine shut-off due to oil pressure.

Emergency stop, oil pressure (Code 2.3.1, PID 100)

Possible reason: Oil pressure is too low. (The engine oil pressure is depended by the engine revolution.)

Reaction: A fault code is generated. The fault code disappears when the oil pressure exceeds the recuperation value.

Action:

• Check the oil level and oil pump.

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

• Check the limit value for oil pressure warning.

Warning, coolant temperature (Code 2.3.2, PID 110)

Possible reason: Coolant temperature too high.

Reaction: A fault code is generated. The fault code disappears when the coolant temperature falls below the limit value.

Action:

• Check the coolant level.

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

Warning, coolant level (Code 2.3.5, PID 111)

Possible reason: Coolant level is too low.

Reaction: A fault code is generated.

Action:

• Check the coolant level.

• Check the sensor cable for breaks and short circuits.

• Check sensor function. Change the sensor as necessary.

NOTICE! The engine is delivered without coolant level sensor.
