To disconnect the CKP sensor, begin by unplugging the cable from the negative battery terminal. The sensor is located on the timing chain cover next to the crankshaft pulley. Then, unplug the electrical connector, and pull out the sensor and harness. Lastly, remove the crankshaft position sensor retaining bolt and sensor. Installation is the reverse of removal, ensuring that the CKP sensor retaining bolt is tightened securely.
