Ignition Coil Resistance

1996 Toyota T100 SR5, 4WD, StandardSECTION Ignition Coil Resistance
  1. Remove necessary components and disconnect electrical connector from ignition coil. Disconnect spark plug wire from ignition coil.
  2. Using ohmmeter, check ignition coil primary resistance between ignition coil positive (+) and negative (-) terminals. These are the terminals that electrical connector was installed on. See Fig 1 and Fig 2. Replace ignition coil if primary resistance is not within specification. See IGNITION COIL RESISTANCE  table.
  3. Using ohmmeter, check ignition coil secondary resistance. See Fig 1 and Fig 2. Replace ignition coil if secondary resistance is not within specification. See IGNITION COIL RESISTANCE  table. Reinstall connector on ignition coil.

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.
