Heated Oxygen Sensor

INSPECTION

1. INSPECT HEATER RESISTANCE OF OXYGEN SENSOR




a. Disconnect the sensor connector.
b. Using an ohmmeter, measure the resistance between terminals +B and HT.

Resistance: 11 - 16 ohms @ 20 °C (68 °F)

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

Torque: 44 Nm (32 ft.lbf)

c. Reconnect the sensor connector.

2. INSPECT OPERATION OF HEATED OXYGEN SENSOR
