Heated Oxygen Sensor:

COMPONENTS




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.
