Inspection
INSPECTION1. 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 kg/sq.cm, 85 psi)
Duration: 20 seconds or less
b. Check the spark plug for thread damage and insulator damage.
HINT: If abnormal, replace the spark plug.
Recommended spark plug:
SK16R11 (DENSO made)
IFR5A11 (NGK made)
c. Check the spark plug electrode gap.
Electrode gap: 1.1 mm (0.043 in.)
2. CRANK POSITION SENSOR NO.1
Using an ohmmeter, measure the resistance between terminals.
RESISTANCE:
At cold 835 - 1,400 ohm
At hot 1,060 - 1,645 ohm
NOTE: "Cold" and "Hot" on the table express 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 crank position sensor No.1
3. CRANK POSITION SENSOR
Using an ohmmeter, measure the resistance between terminals.
RESISTANCE:
At cold 1,630 - 2,740 ohm
At hot 2,065 - 3,225 ohm
NOTE: "Cold" and "Hot" on the table express 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 crank position sensor.
4. IGNITION RELAY
Continuity inspection.
1. Using an ohmmeter, check that continuity exists between each terminal.
Specified condition:
Between terminal 1 and 2 Continuity
Between terminal 3 and 5 No continuity
2. Using an ohmmeter, check that continuity exists between terminals 3 and 5 when the battery voltage is applied across terminals 1 and 2.
