Mazda 3 Service Manual / Electrical / Ignition / Spark Plug Inspection [Skyactiv G 2.0]

Specification

Plug Gap Inspection

CAUTION:

  1. To avoid possible damage to the tip, do not adjust the plug gap.

  2. 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.

  1. If not within the standard specification, replace the spark plug.

Cleaning

CAUTION:

  1. Carbon may adhere to the tip of the spark plug during vehicle delivery or repeated short distance driving during the winter time. If there is any malfunction such as rough idling or start difficulty due to carbon adhesion causing plug fouling, burn off the carbon by performing no-load racing of the engine.

  2. When performing the no-load racing, apply the side brake and foot brake, move the shift lever to neutral (MTX), or the selector lever to P position (ATX) to prevent an accident and serious injury.

  3. To avoid possible damage to the spark plug tip, do not use a wire brush for cleaning.

NOTE:

  1. To avoid possible damage to the tip, use gasoline to clean the spark plugs after removing dirt.

  2. If the accelerator pedal is depressed continuously for a specified time, the engine speed may decrease to the idle speed. This is due to the PCM control operation, which prevents overheating, and it does not indicate a malfunction.

  3. Do not perform no-load racing at high engine speed continuously for 10 s or more

    .

1. If there is carbon adhering to the spark plug, perform no-load racing at 4,000 rpm

for 2 min

, 2 times

.

Visual Inspection

1. Inspect the following items:


Resistance Inspection

1. Measure the resistance of the spark plug using a tester as shown in the figure.
