Ignition Coil

The replacement process starts with removing the air cleaner resonator and outlet duct. Start by removing the ignition coil bolts then disconnecting the engine wiring harness electrical connectors from the ignition coils before extracting the ignition coils from the camshaft cover. Install the ignition coils exclusively after you verify that the camshaft cover ignition coil seals fit correctly before inserting the coils into position. Screw in the ignition coil mounting bolts until the torque reaches 10 Nm (89 lb in). Follow the process by reconnecting engine wiring harness electrical connectors to ignition coils and afterward reinstall the air cleaner resonator along with the outlet duct.

First, remove the air cleaner resonator and outlet duct to change the ignition coil. Refrain from the engine wiring harness electrical connectors to the ignition coils; remove the bolts of the ignition coils and pull the ignition coils from the camshaft cover. When replacing the ignition coils, see that ignition coil seals are in place to the camshaft cover, then proceed to insert ignition coils to the camshaft cover. Mount the ignition coil bolts, then finish tightening them to 10 N.m (89 lb in). Reconnect the engine wiring harness electrical connectors to the ignition coils and lastly, reinstall the air cleaner resonator and outlet duct.

First remove the air cleaner resonantor and outlet duct then replace the ignition coil. Disconnect the engine wiring harness electrical connectors from the ignition coils, remove the ignition coil bolts and remove the ignition coils from the camshaft cover. When replacing the new ignition coils make sure the ignition coil seals are seated properly to the camshaft cover prior to installation of the ignition coils into the camshaft cover. Fit the ignition coil bolts and tighten to 10 Nm (89 lb in). Reconnect the engine wiring harness electrical connectors to the ignition coils and then reinstall the air cleaner resonator and outlet duct.

Begin ignition coil replacement by removing the air cleaner outlet resonator. Begin by disconnecting ignition coil connectors from both ignition coils while removing their retaining bolts. The next step involves eliminating the ignition coils from their installation inside the engine compartment. Before installing the ignition coil make sure ignition coil seals fit properly into the valve cover. Insert the ignition coil retaining bolts then secure them with a torque of 10 Nm (89 lb in). Reconnect the ignition coil connectors and then reinstall the air cleaner outlet resonator.

The initial step for ignition coil replacement involves removing the air cleaner outlet resonator. Disconnect the ignition coil connectors from ignition coils before removing the ignition coils retaining bolts. Begin by removing the ignition coils from inside the engine compartment. When installing the ignition coil first establish proper seal placement between the valve cover and the ignition coil seals. Install the ignition coil retaining bolts in succession before tightening them to 10 N.m (89 lb in) while adhering to the Fastener Notice in Service Precautions. The installation process includes replacing ignition coil connectors before reinstalling the air cleaner outlet resonator.

To replace the Ignition Coil, remove the air cleaner resonator and outlet duct at first. Remove the oil pressure sensor on the engine wiring harness electric connector . Remove the engine wiring harness retainer from oil filter adapter, and engine wiring harness retainers from the Power Steering Pump . Then, pull off the engine wiring harness electrical connectors (1, 4) from the camshaft position (CMP) sensor and the cmp actuator solenoid valve and depress the engine wiring harness retainer (4) from the camshaft cover . Then follow by detaching electrical connectors of the fuel injector harness , heated Oxygen Sensor (HO2S) and engine coolant temperature (ECT) sensor , also from the ignition coils. Disconnect the engine wiring harness conduit delicately from the camshaft cover and move it out of the way. Pull off the Ignition Coil, using Ignition Coil bolts and removing the ignition coils by turning the Ignition Coil bolts on the camshaft cover. For installation, ensure the Ignition Coil seals are seated to the camshaft cover, then install ignition coils and bolt in and tighten them to 10 n.m (89 lb in). Connect the electric connectors onto the ignition coils, fuel injector harness, ho2s, and ect sensors and then reattach the engine wiring harness conduit to the camshaft cover. Connect the electrical connectors (1, 4) to the cmp sensor and cmp actuator solenoid valve and the engine wiring harness retainer to the camshaft cover and retainers to the Power Steering Pump. Finally, join up the electrical connector to the oil pressure sensor , the retainer to the oil filter adapter , and replace the resonator and outlet duct shield of the air cleaner .

Take out the ignition coils from the engine.
