Inspection
INSPECTION1. INSPECT SPARK PLUG
NOTE:
- Never use a wire brush for cleaning.
- Never attempt to adjust the electrode gap on used spark plug.
- Spark plug should be replaced every 192,000 km (120,000 miles).
a. Clean the spark plugs.
Air pressure: Below 588 kPa (6.0 kgf/cm2, 85 psi)
Duration: 20 seconds or less
b. Check the spark plug for any damage on its thread and insulator.
HINT: If damaged, replace the spark plug.
Recommended spark plug:
SK20R11 (DENSO made)
IFR6A11 (NGK made)
c. Check the spark plug electrode gap.
Electrode gap: 1.0 to 1.3 mm (0.039 to 0.051 in.)
2. INSPECT CAMSHAFT POSITION SENSOR
a. Using an ohmmeter, measure the resistance between terminals.
RESISTANCE:
835 to 1400Ohms at cold
1060 to 1645Ohms 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).
HINT: If the resistance is not as specified, replace the camshaft position sensor.
3. INSPECT CRANKSHAFT POSITION SENSOR
a. Using an ohmmeter, measure the resistance between the terminals.
RESISTANCE:
1630 to 2740Ohms at cold
2065 to 3225Ohms at hot
HINT: If the resistance is not as specified, replace the crankshaft position sensor.
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).
4. INSPECT IGNITION RELAY NO.1
a. Check the resistance.
1. Using an ohmmeter, measure the resistance between the terminals.
Standard:
If the result is not as specified, replace the ignition relay.
