Ignition System (2TR-FE): Inspection

  1. INSPECT SPARK PLUG 
    1. Clean the spark plugs.

      Air pressure: Below 588 kPa (6.0 kgf/cm 2  , 85 psi) 

      Duration: 20 seconds or less

    2. Check the spark plug for any damage on its thread and insulator.

      If damaged, replace the spark plug.

      Recommended spark plug: 

      SK20HR11 (DENSO made) 

      ILFR6C11 (NGK made)

    3. Check the spark plug electrode gap.
      1. Using a spark plug gap gauge, measure the electrode gap.

      Electrode gap: 1.0 to 1.1 mm (0.039 to 0.043 in.) 

      Maximum electrode gap: 1.3 mm (0.051 in.) 

      If the result is greater than the maximum, replace the spark plug.

  2. INSPECT CAMSHAFT POSITION SENSOR 
    1. Check the resistance.
      1. Using an ohmmeter, measure the resistance between the terminals.
      CAMSHAFT POSITION SENSOR SPECIFIED CONDITION

      Tester Connection Specified Condition
      1 (G+) - 2 (G-) 835 to 1,400 Ω at COLD
      1 (G+) - 2 (G-) 1,060 to 1,645 Ω at HOT

      HINT:

      Cold and Hot mean the temperature of the coils themselves.

      Cold is from -10 to 50°C (14 to 122°F) and Hot is from 50°C 100 °C (122 to 212°F).

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

  3. INSPECT CRANKSHAFT POSITION SENSOR 
    1. Check the resistance.
      1. Using an ohmmeter, measure the resistance between the terminals.

      CRANKSHAFT POSITION SENSOR SPECIFIED CONDITION

      Tester Connection Specified Condition
      1 (NE+) - 2 (NE-) 1,630 to 2,740 Ω at COLD
      1 (NE+) - 2 (NE-) 2,065 to 3,225 Ω at HOT

      HINT:

      Cold and Hot mean the temperature of the coils themselves.

      Cold is from -10 to 50°C (14 to 122°F) and Hot is from 50 to 100°C (122 to 212°F).

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