Ignition System: Diagnosis Mazda CX-5 I

Ignition Coil Inspection

  1. Perform the spark test and identify the malfunctioning cylinder. (See «ENGINE CONTROL SYSTEM OPERATION INSPECTION [SKYACTIV-G 2.0]»(ref-615397-S33190429702014051000000) ).
  2. Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and perform the spark test again. (See «ENGINE CONTROL SYSTEM OPERATION INSPECTION [SKYACTIV-G 2.0]»(ref-615397-S33190429702014051000000) ). 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.

Plug Gap Inspection

CAUTIONTo avoid possible damage to the tip, do not adjust the plug gap. To prevent damaging the tip, use a wire type plug gap gauge when inspecting the plug gap.
  1. Measure the spark plug gap using a wire type plug gap gauge. If not within the standard specification, replace the spark plug. Spark plug gap Standard: 0.75-1.10 mm {0.030-0.043 in} New spark plug (reference): 0.75-0.85 mm {0.030-0.033 in}
