Ignition Coil F Secondary Circuit

Check these first

• A failed ignition coil F secondary winding
• A worn spark plug or plug boot on coil F
• A cracked coil F tower arcing to ground
• Corrosion at the coil F connector

What to do next

1. Check for spark at the cylinder fed by coil F
2. Inspect the spark plug and boot for coil F
3. Check the coil F tower for carbon tracking
4. Measure ignition coil F secondary resistance
5. Replace ignition coil F if the secondary winding tests bad
6. Clear the code and retest
