Bank 1 Sensor 1

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR
a. Disconnect the oxygen sensor connector.
b. Using an ohmmeter, measure the resistance between terminals +B and HT

Resistance: 11 - 16 Ohms at 20° C (68° F)

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

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

c. Reconnect the oxygen sensor connector.

2. INSPECT OPERATION OF HEATED OXYGEN SENSOR: See "Related Diagnostic Charts" in this section
