Ignition Coil Resistance

WARNING: This page is about a different car, the 1993 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect wiring from ignition coil so ignition coil is isolated from system. Using ohmmeter, measure primary resistance between ignition coil positive (+) and negative (-) terminals. See Fig 1 or Fig 2.

Check secondary resistance between ignition coil positive (+) terminal and high tension wire terminal (coil wire tower). See Fig 3 or Fig 4. Replace ignition coil if resistance is not within specification. See appropriate IGNITION COIL RESISTANCE table.
