INSPECTION

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSORS

(a) Disconnect the oxygen sensor connector.

(a) Disconnect the oxygen sensor connector.

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

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

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

Torque: 44 N·m (450 kgf·cm, 32 ft·lbf) for sensor 1 20 N·m (200 kgf·cm, 14 ft·lbf) for sensor 2

(c) Reconnect the oxygen sensor connector.
