Cylinder #7 Ignition Coil Short Circuit
Code P1267 indicates a short circuit between the high and low sides of the ignition coil for cylinder #7. This typically means the coil's primary or secondary windings have failed, causing a direct electrical short. The engine control module (ECM) detects abnormal current flow and sets this code. This can lead to misfires, reduced power, and potential damage to the ECM or other components if not addressed.
01. Most Common Causes
- Faulty ignition coil on cylinder #7
- Short circuit in wiring or connector to coil #7
- Damaged ECM (rare)
02. Symptoms You Will Notice
- Check Engine Light on
- Engine misfire on cylinder #7
- Rough idle, hesitation, or loss of power
- Possible fuel smell from unburned fuel
03. Step-by-Step Diagnosis
Step 1: Scan for codes and confirm P1267 is present.
Step 2: Visually inspect ignition coil #7 and its wiring for damage or corrosion.
Step 3: Swap coil #7 with another cylinder and see if the code moves.
Step 4: If code moves, replace the faulty coil. If not, test wiring continuity and ECM output.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a shorted coil can cause misfires, reduce fuel economy, and potentially damage the catalytic converter or ECM.
How much does it cost to fix?▼
Typically $50-$150 for a new ignition coil and labor if you DIY; shop labor may add $50-$100.
