Ignition Coil Inspection

  1. Perform the spark test and identify the malfunctioning cylinder. (See ENGINE CONTROL SYSTEM OPERATION INSPECTION (VIN Y) .)
  2. 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 (VIN Y) .)
    • 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.
