WARNING: This page is about a different variant/trim than selected.
CAUTION:
The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.
- Disconnect and isolate the negative battery cable.
- Remove the upper intake manifold. Refer to MANIFOLD, INTAKE, REMOVAL .
- Cover the open intake ports (1) to prevent debris from entering the engine.
- Remove the insulator (2) from the LH cylinder head cover.

.
- Disengage one main wire harness retainer (3) from the left cylinder head cover.
- Disengage one main wire harness retainer (2) from the cylinder head cover and one main wire harness retainer (4) from the cylinder head cover mounting stud.NOTE:

- Remove the CMP sensor. Refer to SENSOR, CAMSHAFT POSITION, REMOVAL
.
- Disengage two injection/ignition harness retainers (1) from the left cylinder head cover.
- Remove the ignition coils. Refer to COIL, IGNITION, REMOVAL
