INSPECTION

PROCEDURE

1. INSPECT AIR FUEL RATIO SENSOR

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
D102-1(HA1A) - D102-2(+B)	20°C (68°F)	1.4 to 3.0 Ω
D102-1(HA1A) - D102-4(A1A-)	Always	1 MΩ or higher

If the result is not as specified, replace the air fuel ratio sensor.
