Heated Oxygen Sensor (Sensor-1 and Sensor-2) Inspection
- Disconnect sensor connector (1).
- Using ohmmeter, measure resistance between terminals "VB" and "GND" of sensor connector.
If found faulty, replace oxygen sensor.
Resistance of oxygen sensor heater
Sensor-1: 2 - 6 ohm at 20 °C, 68 °F
Sensor-2: 4 - 10 ohm at 20 °C, 68 °F
- Connect sensor connector securely.
