Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ignition Coil Resistance
Using a DVOM, measure primary coil resistance between specified coil terminals. See Fig 1-Fig 4 . On Galant, measure between terminals No. 11 and 12. On Mirage measure between terminals No. 1 and 2. On all other vehicles, measure between positive and negative terminals. Measure secondary coil resistance between coil positive terminal and ignition coil tower. Primary and secondary coil resistance should be within specification. See IGNITION COIL RESISTANCE table.
| Application | Primary | Secondary | |
|---|---|---|---|
| 1.5L (VIN A) | .50-.70 | 15,000-22,000 | |
| 2.4L (VIN G) | |||
| Galant | .90-1.20 | 20,000-29,000 | |
| Montero Sport | .67-.81 | 11,300-15,300 | |
| 3.0L (VIN H) | .72-.88 | 12,290-13,920 | |
| 3.5L (VIN P) | .50-.70 | 9000-13,000 | |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
