P0355

Ignition Coil E Primary Control Circuit/Open

Ignition coil Generic OBD-II High

What it means

P0355 means the engine computer has detected an open or fault in the primary control circuit of ignition coil 'E' (the fifth coil). If that coil stops firing its cylinder, the engine misfires and loses power. It usually points to a wiring or connector problem at the coil, or a failed coil.

High

Can I keep driving? Usually drivable but the affected cylinder may not fire, causing a misfire — extended driving with a dead cylinder can damage the catalytic converter, so repair it promptly.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Failed ignition coil 'E'
  2. Open or shorted coil primary control (driver) circuit wiring
  3. Loose or corroded connector at the coil
  4. Faulty coil driver in the ECM/ignition module (rare)

How to diagnose & fix

Work through it in order

  1. Read freeze-frame data and inspect the coil 'E' connector and wiring for damage, corrosion, or a loose pin.
  2. Swap coil 'E' with a neighbouring coil; if the fault follows the coil, replace it.
  3. Check the primary control circuit for opens/shorts back to the ECM or ignition module.
  4. Confirm power and ground at the coil, then clear and re-test.

FAQ

Quick answers

Is it safe to drive with P0355?+
Only briefly. If the cylinder isn't firing the engine will misfire, and a sustained misfire can overheat and damage the catalytic converter.
Can I just clear P0355?+
You can, but it returns until the coil or its control circuit is repaired.
