      *a

      Component without harness connected

      (Oxygen Sensor)

      w/o Dual VVT-i:

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance (w/ Secondary Air Injection System)
      Tester Connection Condition Specified Condition
      1 (HT1B) - 2 (+B) 20°C (68°F) 11 to 16 Ω
      1 (HT1B) - 4 (E2) Always 10 kΩ or higher
      Standard Resistance (w/o Secondary Air Injection System)
      Tester Connection Condition Specified Condition
      1 (HT1A) - 2 (+B) 20°C (68°F) 11 to 16 Ω
      1 (HT1A) - 4 (E2) Always 10 kΩ or higher

      If the result is not as specified, replace the oxygen sensor.
