  1. Disconnect the sensor connector.

  1. Measure the resistance of the sensor.

    Bank 1 standard resistance:
    Bank 1
    Tester Connection
    		Specified Condition
    1 (HT1B) - 2 (+B)
    		11 to 16 Ω at 20°C (68°F)
    1 (HT1B) - 4 (E2)
    		10 kΩ or higher
    Bank 2 standard resistance:
    Tester Connection
    		Specified Condition
    1 (HT2B) - 2 (+B)
    		11 to 16 Ω at 20°C (68°F)
    1 (HT2B) - 4 (E2)
    		10 kΩ or higher
    If the result is not as specified, replace the sensor.

  1. Connect the sensor connector.
