Main Oxygen Sensor Inspection
INSPECT HEATER RESISTANCE OF MAIN HEATED OXYGEN SENSORMain Heated Oxygen Sensor Location:
- Disconnect the oxygen sensor connector.
- Using an ohmmeter, measure the resistance between the terminals +B and HT.
Resistance: At 20°C (68°F): 11 - 16 Ohms
- If the resistance is not as specified, replace the sensor.
Torque: 44 Nm (32 ft.lb)
- Reconnect the oxygen sensor connector.
