Ignition Coil Inspection

1.  Perform the spark test and identify the malfunctioning cylinder.

2.  Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and reperform the spark test.

•  If the spark is not normal due to a malfunctioning ignition coil, replace that ignition coil.

•  It is unlikely that all four ignition coils fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil, and replace it.

1.  Remove the fresh-air duct and air cleaner as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

U.K. specs.

1.  Set the air cleaner cover out of the way. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

2.  Remove the fresh-air duct and air cleaner case as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

3.  Disconnect the ignition coil connector.

4.  Measure the resistance between each terminal on the ignition coil connector using an analog circuit tester.
