Ignition Coil Check

  1. Remove ignition coil cover. Disconnect 6 ignition coil 3-pin connectors. Turn ignition on. Measure voltage between ground and each ignition coil connector terminal No. 3 (Black/Yellow wire). If battery voltage is present, go to next step. If battery voltage is not present, repair open circuit in Black/Yellow wire between ignition coil and 15-amp fuse No. 11 located in underdash fuse/relay box.
  2. Turn ignition off. Measure continuity between ignition coil 3-pin connector terminal No. 2 (Black wire) and ground. If continuity is present, go to next step. If continuity is present, repair open circuit in Black wire between ignition coil and ground.
  3. Disconnect PCM 31-pin connector. Measure continuity between PCM 31-pin connector terminals and ground. See PCM 31-PIN CONNECTOR TERMINAL IDENTIFICATION . If continuity is present between designated PCM connector terminal and ground, repair short circuit in appropriate wire between ignition coil and PCM. If continuity is not present, go to next step.
