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.
- Disconnect ignition coil 2-pin harness connector. Using DVOM, measure primary resistance between ignition coil terminals "A" and "B". See Fig 1. Resistance reading should be as specified in table. See IGNITION COIL RESISTANCE SPECIFICATIONS table. If resistance reading is as specified, go to next step. If resistance reading is not as specified, replace ignition coil.
- Using a DVOM, measure secondary resistance between ignition coil terminal "A" and coil tower boot socket. See IGNITION COIL RESISTANCE SPECIFICATIONS table. If resistance reading is not as specified, replace ignition coil.
