Ignition Coil Resistance
- Using an ohmmeter, measure primary coil resistance for cylinders No. 1 and 4 between coil connector terminals No. 1 and 3. Measure resistance for cylinders No. 2 and 3 between connector terminals No. 2 and 3. See Fig 1 . See DIS IGNITION COIL RESISTANCE table.
- To measure secondary coil resistance, disconnect ignition coil connector. Measure resistance between coil towers No. 1 and 4 and between coil towers No. 2 and 3. See DIS IGNITION COIL RESISTANCE table. Replace coil if readings are not within specification.
