crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.
The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. It is also commonly the primary source for the measurement of engine speed in revolutions per minute.
Crank sensors in engines are usually comprised of magnets and an inductive coil. They are principally based on the Hall effect. Common mounting locations include the main crank pulley, the flywheel, or occasionally on the crankshaft itself.
Some engines, such as GM's Premium V family utilise crank position sensors which read a reluctor ring integral to the Harmonic Balancer. This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the crankshaft (and thereby all connected components) at any given time.

After replacing the camshaft position sensor, still the same error code is coming.-------- Then in that case, disconnect the negative terminal of battery for 15 minutes, then reconnect and check.In some cases, this resets the PCM.( pcm means power control module). Its also known as cars computer.------
But if that is not helping, then problem relates to PCM.The pcm is either faulty, or its connection from, camshaft position sensor is loose.
There are three terminals to camshaft position sensor.
1 = ground.
2 = signal to PCM.
3 = +12V (or maybe +5V). ----------- One wire is only white, other is black/white stripe and third one is only black wire. The white on top, black with white stripe in the middle and black on the bottom.white is +12 (or whatever's coming off the alternator/battery). Black is ground and should show no resistance if you test it against the engine block, frame, or negative battery post. Black with white stripe is the signal wire.-------- So you have to check the PCM to camshaft position sensor wire, that is black/white stripe.Either this wire is not got connected or the PCM is faulty.So its not detecting the camshaft sensor, and its showing this error code, even though, you have replaced, the camshaft sensor. -------------- Get the PCM checked at professional auto repair store, or at autozone service center , if its faulty, then it has to be replaced.--------- This should help.Thanks.Helpmech.
