(a) Disconnect the oxygen sensor connector.

Bank 1 Sensor 1

Bank 1 Sensor 2

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

Resistance: At 20°C (68°F): 11 - 16 ohm 

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

Torque: 20 N.m (200 kgf.cm, 14 ft.lbf) 

(c) Reconnect the oxygen sensor connector.
