A crankshaft sensor is used on internal combustion engines to control the timing of the ignition system and other important engine functions. A broken crankshaft sensor can cause problems with engine starting and operation. It may also cause higher fuel consumption and decreased engine performance. If you notice those problems with your vehicle, check for a crankshaft sensor problem.
Step 1
Disconnect the ground cable from the battery. With a floor jack, lift the front of the vehicle so you can crawl under the engine. Support the car with jack stands for safety.
Step 2
Disconnect the wires connecting the battery to the starter. Label the wires to prevent confusion when you need to put them back.
Step 3
Remove the nuts or bolts that hold the starter motor using an appropriate socket.
Step 4
Remove the starter so you can access the crankshaft sensor. Once this is removed, you should be able to see the crank shaft sensor on the engine block.
Step 5
Remove the connection on the center of the crank shaft sensor using a screwdriver. Press and slide the connector from the sensor. The sensor is held on by one bolt.; remove this by using the appropriate socket.
Step 6
Place a door-panel remover on the side of the crankshaft sensor. Pry the sensor loose from the engine block and wiggle it around until it can be removed.
Check for possible problems. If the crankshaft sensor is corroded, you will have to replace it with a new one.
