Ignition Coil Test

1998 Acura Integra GS, 4D Sedan, AutomaticSECTION Ignition Coil Test
  1. Turn ignition off. Disconnect ignition coil 4-pin connector. Measure primary winding resistance between ignition coil connector terminals No. 2 (Black/Yellow wire) and No. 3 (Green wire). Resistance should be .36-.44 ohm at 68°F (20°C). See Fig 1.
  2. Measure secondary winding resistance between ignition coil connector middle terminal No. 2 (Black/Yellow wire) and secondary terminal (coil tower). Resistance should be 10,800-16,200 ohms at 68°F (20°C).
  3. Measure resistance between ignition coil connector terminals No. 3 (Green wire) and No. 4 (Blue wire). Replace coil if resistance is not within specification. If resistance is as specified, check for continuity between ignition coil terminals No. 1 (Black/Yellow wire) and No. 2 (Black/Yellow wire). If continuity does not exist, replace ignition coil.

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.
