Engine hesitates –
Momentary lack of
response as accelerator
is depressed. Can occur
at all vehicle speeds.
Usually most severe when
first trying to make
vehicle move, as from a
stop sign.Spark plug faulty or plug gap out of
adjustment“Spark Plug Inspection in Section 1H”
Leaky high-tension cord“High-Tension Cord Inspection in Section 1H”
Fuel pressure out of specification“Fuel Pressure Check”

variation under steady
throttle or cruise. Feels
like vehicle speeds up
and down with no change

3Contact coil circuit (horn and audio control switch
circuit) check (non cruise control model)
1) Check for continuity between each terminal of horn
switch terminals [A] and audio control switch terminals
[B] (if equipped) as shown in figure.
Is each measured resistance 3
Ω or less?Go to Step 5. Replace contact coil. Step Action Yes No

Inspection of Intermittent and Poor
Connections
S6RW0D8204047
Most intermittents are caused by faulty electrical
connections or wiring. When a check for proper
connection is requested in a diagnostic flow, perform
careful check of suspect circuits.
If any abnormality is found, repair or replace as a wire
harness assembly.
• Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).• Dirt or corrosion on the terminals. The terminals must
be clean and free of any foreign material which could
impede proper terminal contact.
However, cleaning the terminal with a sand paper or
the like is prohibited.
• Damaged connector body, exposing the terminals to
moisture and dirt, as well as not maintaining proper
terminal orientation with the component or mating
connector. 4Contact coil circuit (horn, audio control and cruise
control switch circuit) check (cruise control model)
1) Check for continuity between each terminal of horn
switch terminals, audio control switch terminals and
cruise control switch terminals as shown in figure.
Is each measured resistance 3
Ω or less?Go to Step 5. Replace contact coil.
5Contact coil circuit check
1) Measure resistance between each terminal and other
terminal.
Is each measured resistance infinity?Contact coil and its
circuit are good
condition.Replace contact coil. Step Action Yes No
