2. Disconnect engine control sensor wiring connector from camshaft position sensor.
3. Remove camshaft position sensor retaining screws and camshaft position sensor from camshaft position sensor housing.
4. If removing camshaft position sensor housing from the cylinder block, proceed with Removal Step 5. If not removing camshaft position sensor housing, proceed to installation Step 6.
