Ignition Coil Test
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1998 Acura Integra, 1998 Acura 3.5RL, 1998 Acura 3.2TL, 1998 Acura 3.0CL, and 1998 Acura 2.5TL. However, it is still accessible from the selected car via links, so may be relevant.
- 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.
- 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).
- 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.
