Ignition Coil Resistance
WARNING: This page is about a different car, the 1997 Lexus SC 300. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect electrical connector and distributor wire from ignition coil. To measure primary resistance, measure resistance between terminals of ignition coil.
- To measure secondary resistance, measure resistance between positive wire terminal at ignition coil and coil secondary tower. See IGNITION COIL POSITIVE TERMINAL IDENTIFICATION table. If resistance is not as specified, replace ignition coil. See IGNITION COIL RESISTANCE table.
