What this code generally means, its most common causes, and how serious it is.
The crankshaft position sensor (CKP) tells the control module where the engine is in its cycle and how fast it's turning — essential information for timing ignition and fuel injection. This code signals a problem in that circuit.
Unlike many other sensors, this one matters enough that the engine can stall or refuse to restart if the signal is lost, sometimes without warning. This is one of the more serious codes on this list — avoid extended driving and get it checked promptly.

Yes, that's a classic symptom of a full failure of this sensor: the engine cranks but won't start, for lack of timing synchronization.
If the light is flashing or the car has already stalled unexpectedly, it's safer to have it checked or towed rather than risk a breakdown in traffic.
