INSPECTION







INSPECT HEATER RESISTANCE OF A/F SENSORS
(Bank 1 sensor 1, Bank 2 Sensor 1)
a. Disconnect the A/F sensor connector.
b. Using an ohmmeter measure the resistance between terminals +B and HT.
If the resistance is not as specified, replace the sensor.

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

c. Reconnect the A/F sensor connector.
