April 5, 2026: LEMON Manuals is launched! Read the announcement.

Ignition System: Inspection

INSPECT SPARK PLUG

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

Air pressure: Below 588 kPa (6kg/cm ² , 85 psi)

Duration: 20 seconds or less

INSPECT CAMSHAFT POSITION SENSOR
1. Using an ohmmeter, measure the resistance between the terminals.
  RESISTANCE:
  
  1630 to 2740 Ω cold
  
  2065 to 3225 Ω at hot
  
  NOTE: "Cold" and "Hot" mean the temperature of the coils themselves. "Cold" is from -10°C (14°F) to 50°C (122 °F) and "Hot" is from 50 °C (122 °F) to 100 °C (212 °F).
INSPECT CRANKSHAFT POSITION SENSOR
1. Using an ohmmeter, measure the resistance between the terminals.
  RESISTANCE:
  
  985 to 1600 Ω at cold
  
  1265 to 1890 Ω hot
  
  NOTE: "Cold" and "Hot" mean the temperature of the coils themselves. "Cold" is from - 10°C (14°F) to 50 °C (122 °F) and "Hot" is from 50 °C (122 °F) to 100 °C (212 °F).
