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.

Follow the manual and do it every 60K miles. Even after that the new one is made of the same reinforced plastic so it has to be changed at 120K miles. At those same intervals Hyundai calls for a heavy check which adds another $250-300 to the tab. I got the belt changed for about $550. Almost every other interval check can be accomplished by a reputable mechanic or shop. The heavy checks and belt replacement should be done by Hyundai or your warranty may not be honored.

The above statement is GREAT!!! The wheel-well piece folds down across the area you need to be in. There are 2 screws to undo this part. Push it back and there is a cap that unscrews which holds the wires and socket he is talking about. Unscrew the cap, unscrew the wire and housing. The bulb comes out. You pull the wire harness off and install the new bulb. It has a triangular push-in and it has to go just right so take note of how it comes out. Also, being a halogen light bulb, do not touch the bulb with your hands - the oils will make it explode.

Remove the plastic cover that goes over the engine (the one with the Hyundai logo).
At this point, you will see the cables that goe to each fo the spark plugs.
Noting their position, remove them.
The spark plugs are ready to be removed, turn counterclockwise and replace with manufacturer recomended ones.
