P0355 Ignition Coil "E" Primary/Secondary Circuit
An electrical fault is detected in both the primary and the secondary circuit of ignition coil E. The ECU cannot drive the coil correctly, so the cylinder served by coil E misfires or does not fire at all. Causes: an open or shorted primary control wire, an internal coil winding fault, a failed igniter/driver, or wiring or connector damage at the coil.
