Hi, My daughter has just purchased a Fiat Punto 1.2 16v. We have had intermittent problems with the car, she will be driving along at any speed and the revs will drop and the engine will cut out. We took the car to a diagnostic centre, where they think it may be the Crankshaft Sensor, as this is the crankshaft position detector, which detects when the engine needs a spark and fuel!!
Thanks

A bad crankshaft sensor on a 2.3 Ford may cause the car to not start. A bad crankshaft sensor can crank, just not start.
A bad crankshaft position sensor will cause your Kia Sorrento to run rough. The bad crankshaft position sensor can also cause your Kia to not start.
When a crankshaft sensor is bad the engine will not run. The sensor is not usually intermittent, it is either good or bad.
A crankshaft sensor can go bad if due to an oil leak. If oil breaches the sensor itself it will burn out.
No.
No, a bad crankshaft sensor would cause the car not to start and run.

no
A bad crankshaft sensor can have several symptoms. The engine could stall, backfire, be sluggish or not run at all.
It could be a bad crankshaft sensor or a bad camshaft sensor.
Check to see if the wiring is damaged.
An intermittent crankshaft sensor will not let the engine fire the correct times. This can definitely cause a misfire for the engine.
