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 plug.
Air pressure: Below 588 kPa (6.0 kg/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:
SK16R11 (DENSO made)
IFR5A11 (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 the terminals.
RESISTANCE:
835 to 1400 Ohms at cold
1060 to 1645 Ohms 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 2740 Ohms at cold
2065 to 3225 Ohms 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 crankshaft position sensor.
4. INSPECT IGNITION RELAY NO.1
a. Check the resistance.
1. Using an ohmmeter, measure the resistance between the terminals.
