Cataloged as a camshaft position sensor; many listings note cam/crank because this part number serves the same role in different model years/applications.
Does it include the O-ring?
Yes, listings commonly include the sealing O-ring for proper installation. Inspect packaging and replace the O-ring if damaged.
Do I need to reprogram the ECM after installation?
