Removal Procedure
Notice: Numbers in text in parenthesis correspond to numbered components in image.
1. Disconnect the wiring harness (1) from the Crankshaft Position (CKP) sensor pigtail.
2. Securely attach a scrap piece of wire about 36 inches long to the CKP sensor pigtail. Later, this piece will be used as a pull wire to guide the new
sensor pigtail back through the same routing.
3. Raise and support the vehicle. Refer to Vehicle Lifting and Jacking.
4. Remove the oil filter and capture any lost engine oil in a container.
5. Loosen the oil cooler lines at the engine block. Back out the fittings far enough in order to gain sufficient clearance for the sensor pigtail connector
to pass between the oil cooler lines and the side of the engine block.
6. Remove the fastening bolt for the CKP sensor (1).
7. Remove the CKP sensor and the O-ring seal from the engine block.
8. Remove the CKP sensor pigtail. Observe the routing of the pigtail. Gently pull the CKP sensor pigtail down through the routing path and out.
Guide the pigtail connector along the top of the oil cooler lines around to the side of the engine block. Pass the connector between the lines and the
block at the point of the widest gap. Stop when the pull wire is exposed at both ends of the routing path.
9. Disconnect the sensor from the pull wire.
