You need to remove the air cleaner resonator and outlet duct, disconnect the engine wiring harness electrical connector from the oil pressure sensor, disconnect the engine wiring harness retainer from the oil filter adapter, disconnect the engine wiring harness retainers from the power steering pump, disconnect the engine wiring harness electrical connectors from the camshaft position (CMP) sensor, and the CMP actuator solenoid valve, then disconnect the engine wiring harness retainer from the camshaft cover, disconnect the engine wiring harness electrical connectors from the fuel injector harness, the heated oxygen sensor (HO2S), and from the engine coolant temperature (ECT) sensor, then disconnect the engine wiring harness electrical connectors from the Ignition Coils, disengage the engine wiring harness conduit from the camshaft cover, and position aside, then remove the ignition coil bolts and the ignition coils from the camshaft cover.

First, you should turn the Ignition Lock Cylinder to the accessory (ACC) position, then push the lock cylinder in until the pin locks in the lock module, next install the steering column trim covers.

You need to raise and support the vehicle only high enough to access the Knock Sensor (KS) through the wheelhouse, then remove the left wheelhouse liner, disconnect the engine wiring harness electrical connector from the KS, remove the KS retaining bolt, and the KS from the engine block.
