A fault is detected on the secondary (high-voltage) side of ignition coil E. The spark delivered to the plug is missing or too weak, causing a misfire on the cylinder served by coil E. Causes: a worn spark plug or wide gap, a cracked coil or boot, carbon tracking, or an open or leaking secondary winding.
Affected components
- Ignition coil e
- Spark plug cyl e
- Ignition secondary lead
Common causes
- High likelihood: Spark plug worn, fouled or with excessive electrode gap
- Medium likelihood: Secondary breakdown inside coil E
- Low likelihood: Spark lead or boot cracked
