Heated Oxygen Sensor

Heated Oxygen Sensor:

COMPONENTS





INSPECTION
1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR

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

Resistance:
at 20 °C (68 °F) 11 - 16 ohms
at 800 °C (1,472 °F) 23 - 32 ohms
If the resistance is not as specified, replace the sensor.
Torque: 20 Nm (200 kg.cm, 14 ft.lb)

c. Reconnect the oxygen sensor connector.
