5. Remove these wire harness connectors and their clamps from the intake manifold:
^ Intake air temperature (IAT) sensor connector
^ Throttle actuator connector
^ Manifold absolute pressure (MAP) sensor connector
^ Evaporative emission (EVAP) canister purge valve connector
^ Intake manifold tuning (IMT) actuator connector

6. Remove the upper cover mounting bolts and nuts sequentially in two or three steps, then remove the upper cover.





7. Remove the intake manifold mounting bolts and nuts sequentially in two or three steps, then remove the intake manifold.
