Scion 90919-02256 Ignition Coil Assembly

To disconnect the cable from the negative battery terminal, start by removing the engine cover on 2009 and earlier models by taking off the mounting fasteners and lifting it off. On 2010 and later models, lift the engine cover up from the rear and then the front, removing it from the mounting pins. For V6 engines, pry the engine cover up from the rear and remove it from the mounting pins. To access the rear ignition coils, remove the upper intake manifold. Each ignition coil/igniter assembly is secured by one bolt, so unscrew the bolt, disconnect the electrical connector, and pull the coil/igniter assembly straight up using a twisting motion. The individual ignition coil boot directly mounts over each spark plug. Installation is the reverse of removal.
