Notice:
in this section, the terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately -10 to 50°c (14 to 122°f). "Hot" means approximately 50 to 100°c (122 to 212°f).
Notice:
If a dtc is present, perform troubleshooting in accordance with the procedure for that dtc.
Notice:
If sparks do not occur, perform the spark test.
Torque: 25 n*m (254 kgf*cm, 18 ft.*Lbf)
Torque: 9.0 N*m (92 kgf*cm, 80 in.*Lbf)
Result
1. Replace the ignition coil with a normal one.
2. Perform the spark test again.
Result
1. Disconnect the ignition coil connector.
2. Turn the ignition switch on.
3. Measure the voltage of the wire harness side connector.

Result
Standard insulation resistance:
10 m or more
Hint:
If the electrode is dry, the spark plug is functioning properly. If the electrode is damp, proceed to the next step.
If there is damage, replace the spark plug.
Recommended spark plug
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.
Electrode gap for new spark plug: 1.0 To 1.1 Mm (0.039 To 0.043 In.)
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 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.
