Ignition Coil Resistance - Miata, Protege & Protege5

WARNING: This page is about a different car, the 2003 Mazda Protege5, 2003 Mazda Protege, 2003 Mazda MX-5 Miata, 2003 Mazda MPV, and 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Using an ohmmeter, measure secondary resistance between coil towers No. 1 and 4 and between coil towers No. 2 and 3. See Fig 1. Resistance should be as specified in table. See IGNITION COIL RESISTANCE SPECIFICATIONS table. If resistance is not as specified, replace appropriate ignition coil.
