Signs of a Bad Crankshaft Position Sensor

A weak crankshaft position sensor can make your engine act haunted for a second, then leave you stuck with a no start or a rough run. You might notice slow cranking, a brief start that dies, or a shaky idle that feels worse once the engine warms up. Sometimes the clues show up while you drive, with drops in RPM, poor throttle response, or sudden stumbles. The tricky part is that these signs can overlap, so the real cause may not be what you expect.
