Ignition Coil Resistance

Disconnect negative battery cable. Remove oil filler cap. Remove timing belt cover and gasket, located above ignition coils on top of cylinder head.
Remove PCV hoses. Disconnect engine wiring clamps on ignition coils. Disconnect electrical connectors from ignition coils.
Using ohmmeter, check ignition coil primary resistance between positive (+) and negative (-) terminals of each ignition coil. These are the terminals that electrical connector was installed on.
Replace ignition coil if primary resistance is not within specification. See IGNITION COIL RESISTANCE table.
Ignition coil secondary resistance cannot be checked. Reinstall electrical connectors on ignition coils, timing belt cover, gasket and negative battery cable.
