Malfunction Criteria And Threshold Value(S)

Number of teeth differs by more than 2.

Crankshaft tooth count incorrect at reference gap is detected.

Signal Implausible/Signal Missing:

Engine stop request = true

Engine running after engine stop request = true => Detection of symptom SIGNAL MISSING

Flag for crankshaft acquisition synchronized = OFF

Continuous camshaft signal edge counter > 3

First tooth detected after engine stop = true

=> Detection of symptom SIGNAL IMPLAUSIBLE

First tooth detected after engine stop = false

=> Detection of symptom SIGNAL MISSING

Loss of Synchronization:

Crankshaft synchronization lost

=>Detection of symptom SYNC_LOSS

Crankshaft missing teeth counter = 2

Implausible Tooth Period:

Before crankshaft synchronization:

Invalid crankshaft tooth period = true

=> Detection of symptom TOOTH_PERIOD

After crankshaft synchronization:

Invalid crankshaft tooth period = true

=> Detection of symptom TOOTH_PERIOD
