Failure Strategy Of Crankshaft Position Sensor Of Cummins Generator Set

The engine of the 290kW Cummins generator set adopts the Cummins patented PT fuel system, which enables the set to have higher reliability, durability, power and fuel economy while meeting environmental emissions. So do you know what its crankshaft position sensor failure strategy is?

(1) The concept of failure strategy. The so-called failure strategy is the operation mode of the electronically controlled diesel engine under the fault state. When the diesel engine is in the following conditions, the control strategy will enter the Limphome state.

1. The crankshaft position sensor is damaged or the signal circuit is open or short circuited.

2. The camshaft phase sensor is damaged or the signal circuit is open or short circuited.

3. The oil pressure sensor of the common rail is damaged or the circuit is open or short circuited.

4. The oil metering valve of the high-pressure oil pump is damaged or the drive circuit is open or short-circuited.

5. The electronic throttle sensor is damaged or the signal circuit is open or short-circuited.

(2) Crankshaft position sensor failure strategy. When the ECU judges that the crankshaft position sensor or the camshaft position sensor signal is faulty, the sensor is damaged or the signal circuit is damaged (open circuit or short circuit), the ECU takes the following measures:

1. Turn on the fault light.

2. Generate fault codes: P0008, P0340, P0341, P0335, P0336.

3. The diesel engine continues to work by relying on a single sensor.

4. There is no obvious influence on the power performance of diesel engine.

5. The starting time may be slightly longer than normal.

6. The throttle feels normal.

7. There is no obvious impact on operation, but fuel consumption and emissions may become worse.
