On-Vehicle Inspection [08/2014 - ]: Procedure

PERFORM SPARK TEST

Check for DTCs (Refer to DTC Check / Clear [08/2014 - ] ).
NOTE:
If any DTC is present, perform troubleshooting in accordance with the procedure for that DTC.
Remove the ignition coils and spark plugs (Refer to Removal [08/2014 - ] ).

Disconnect the 4 fuel injector connectors.

Ground the spark plug. (Step 5)
Check that spark occurs while the engine is being cranked. (Step 6)
NOTE:
- Be sure to ground the spark plugs when checking them.
- Do not crank the engine for more than 2 seconds.
  Cranking will stop if the power switch is pushed again for models with cranking holding function.
- If a spark plug has been struck or dropped, replace it.
- If an ignition coil has been struck or dropped, replace it.
HINT:
- If spark does not occur for any cylinder, perform the following Inspect Ignition Coil and Spark Test procedure.
- Repeat steps 3 to 6 for each spark plug and ignition coil.

Connect the 4 fuel injector connectors.

Install the ignition coils and spark plugs (Refer to Installation [08/2014 - ] ).
Clear the DTCs (Refer to DTC Check / Clear [08/2014 - ] ).

INSPECT IGNITION COIL AND SPARK TEST

Perform a spark test.

Replace the ignition coil with a known good one.
Set the vehicle to inspection mode (Refer to Inspection Mode Procedure [08/2014 - ] ).

Perform the spark test again.

Perform a spark test.

Replace the spark plug with a known good one.
Set the vehicle to inspection mode (Refer to Inspection Mode Procedure [08/2014 - ] ).

Perform the spark test again.

Result

Result	Action
NG	Inspect the ignition system (Refer to DTC P0351: Ignition Coil "A" Primary / Secondary Circuit; DTC P0352: Ignition Coil "B" Primary / Secondary Circuit; DTC P0353: Ignition Coil "C" Primary / Secondary Circuit; DTC P0354: Ignition Coil "D" Primary / Secondary Circuit [08/2014 - ] ).
OK	Replace the spark plug

CHECK SPARK PLUG

Check the electrode.

TEXT IN ILLUSTRATION

Ground

Using a megohmmeter, measure the resistance.
Standard Resistance

10 MΩ or more

If the result is 10 MΩ or less, clean the plug and measure the resistance again.

HINT:

If a megohmmeter is not available, perform the following simple inspection instead.

Alternative inspection method:

Quickly accelerate the engine to approximately 2500 rpm 5 times.
Remove each spark plug (Refer to Removal [08/2014 - ] ).
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.

Check the spark plug for any damage to its threads and insulator.

If there is any damage, replace the spark plug.

RECOMMENDED SPARK PLUG

Manufacturer	Spark Plug Type
DENSO	SC20HR11
DENSO	SC16HR11

Check the spark plug electrode gap.

TEXT IN ILLUSTRATION

*a	Spark Plug Electrode Gap

Maximum Electrode Gap for Used Spark Plug

Electrode Gap
1.3 mm (0.0512 in.)

If the gap is greater than the maximum, replace the spark plug.

Electrode Gap for New Spark Plug

Electrode Gap
1.0 to 1.1 mm (0.0394 to 0.0433 in.)

Clean the spark plugs.

If the electrode has traces of wet carbon, clean the electrode with a spark plug cleaner and then dry it.

Standard air pressure

588 kPa (6.0 kgf/cm² , 85 psi)

Standard duration

20 seconds or less.

HINT:

Only use the spark plug cleaner when the electrode is free of oil. If the electrode has traces of oil, use gasoline to clean off the oil before using the spark plug cleaner.

Install the spark plug (Refer to Installation [08/2014 - ] ).
