Ignition System (1NZ-FXE): Inspection

INSPECT SPARK PLUG

NOTE:

Do not clean the spark plug with a wire brush.
Do not adjust the gap of the used spark plug.

Clean the spark plug.

Using a spark plug cleaner, clean the spark plug.

HINT:

If the electrode is wet, dry it first, then clean it with a spark plug cleaner.
If the spark plug is wet with oil, remove the oil with gasoline before using a spark plug cleaner.

Check the appearance.

Check that the threads or insulator of the spark plug are not damaged.

Inspect the gap.
1. Using a spark plug gap gauge, measure the gap of the spark plug.
  Standard: 1.0 to 1.1 mm (0.039 to 0.043 in.)
  
  Maximum: 1.2 mm (0.047 in.)
  
  If the gap is greater than maximum, replace the spark plug.

INSPECT CAMSHAFT POSITION SENSOR

Inspect the resistance.

Using an ohmmeter, measure the resistance between the terminals.

Standard:

RESISTANCE CHECK SPECIFIED CONDITION

Tester Connection	Specified Condition
1 (G+) - 2 (G-)	1,630 to 2,740 Ω (Hot)
1 (G+) - 2 (G-)	2,065 to 3,225 Ω (Cold)

Fig 4: Inspecting Camshaft Position Sensor

NOTE: "Cold" and "Hot" mean the temperature of the parts themselves. "Cold" is from -10 to 50°C (from 14 to 122°F) and "Hot" is from 50 to 100°C (from 122 to 212°F).

If the resistance is not as specified, replace the camshaft position sensor.
