INSPECTION

1. INSPECT HEATER RESISTANCE OF A/F SENSOR
(a) Disconnect the A/F sensor connector.





(b) Using an ohmmeter, measure the resistance between terminals +B and HT

Resistance: 0.8 - 1.4 Ohms at 20 °C (68 °F)

If the resistan6e is not as specified, replace the sensor.

Torque: 44 N.m (450 kgf.cm, 32 ft.lbf)

(c) Reconnect the A/F sensor connector.
2. INSPECT OPERATION OF A/F SENSOR
