Ignition Coil Resistance Test (Accent, Elantra & Tiburon 2.0L)

2003 Hyundai Sonata GLS, AutomaticSECTION Ignition Coil Resistance Test (Accent, Elantra & Tiburon 2.0L)
NOTE: Ignition coil-1 is for cylinders No. 1 and 4, and ignition coil-2 is for cylinders No. 2 and 3.
  1. Turn ignition off. Disconnect both 2-pin ignition coils harness connectors. Measure primary coil resistance between terminals No. 1 and 2 of each ignition coil connector (component side). See Fig 1. See DIS IGNITION COIL RESISTANCE  table. If resistance is as specified, go to next step. If resistance is not as specified, replace ignition coil.
  2. Leave ignition coils harness connectors disconnected, and disconnect all spark plug wires (ignition coil side). Measure secondary coil resistance between high-voltage coil towers No. 1 and 4, and between coil towers No. 2 and 3. See Fig 1. See DIS IGNITION COIL RESISTANCE  table. If resistance is not as specified, replace 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.
