Ignition Coil Inspection
- Perform the spark test and identify the malfunctioning cylinder. (See Engine Control System Operation Inspection .)
- Replace the ignition coil/ion sensor of the malfunctioning cylinder with that of a normal cylinder, and perform the spark test again. (See Engine Control System Operation Inspection
.)
- If the spark is not normal due to a malfunctioning ignition coil/ion sensor, replace that ignition coil/ion sensor.
- It is unlikely that all four ignition coil/ion sensors fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil/ion sensor, and replace it.
