To remove the crankshaft position sensor, you will need a wrench or socket. First, disconnect the electrical connector from the sensor. Then, remove the two bolts that hold the sensor in place. Once the bolts are removed, you can pull the sensor straight out of the engine block.
When reinstalling the crankshaft position sensor, be sure to tighten the bolts securely. If the bolts are not tight, the sensor will not be able to function properly and your vehicle will not start.
