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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 (HA1A) - 2 (+B)
    		20°C (68°F)
    		1.8 to 3.4 Ω
    1 (HA1A) - 4 (A1A-)
    		-
    		10 kΩ or higher
    If the resistance is not as specified, replace the air fuel ratio sensor.
