Camshaft Sensor Timing
- Remove No. 1 spark plug. Bring No. 1 cylinder to TDC on compression stroke. Mark harmonic balancer and rotate engine to 25° ATDC. Remove plug wires from coil assembly.
- Using removal tool (J-28742-A) or equivalent, remove terminal "B" of sensor 3-way connector on module side. Install jumper wire into terminal "B". Connect wire that was removed to jumper wire. See Fig 1.
- Connect voltmeter between jumper wire and ground. Turn ignition to "ON". Rotate camshaft sensor counterclockwise until sensor switch just closes. This indicated by the voltage reading going from 5-12 volts to 0-2 volts.
- Low voltage indicates switch is closed. Tighten retaining bolt. Install spark plug and wires. Remove jumper wire and install wire in terminal "B".
