2. CHECK SPARK PLUG
(a) Check the electrode.
(1) Using a megohmmeter, measure the insulation
resistance.
Standard insulation resistance:
10 M
or more
HINT:
• If a megohmmeter is not available, perform
the following simple inspection instead.
• If the result is 10 M
or less, clean the plug
and measure the resistance again.
(b) Alternative inspection method:
(1) Quickly accelerate the engine to 4,000 rpm 5
times.
(2) Remove the spark plug.
(3) Visually check the spark plug.
If the electrode is dry, the spark plug is
functioning properly. If the electrode is damp,
proceed to the next step.
(c) Check the spark plug for any damage on its threads
and insulator.
If there is damage, replace the spark plug.
Recommended spark plug
(d) Check the spark plug electrode gap.
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than the maximum, replace the
spark plug.

PROBLEM SYMPTOMS TABLE
HINT:
• Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms
are listed in order of probability in the "Suspected area"
column of the table. Check each symptom by checking the
suspected areas in the order they are listed. Replace parts
as necessary.
• The Matrix Chart is divided into 2 chapters. When
troubleshooting, check Chapter 1 first. If instructions are
given in Chapter 1 to proceed to 2, proceed as instructed.
• If the instruction "Proceed to next circuit inspection shown
in problem symptoms table" is given in the flowchart for
each circuit, proceed to the next suspected area in the
table.
• If the problem still occurs even though there are no
malfunctions in any of the circuits, check the ECM and
replace it if necessary.
