Oxygen Sensor: Testing and Inspection

INSPECTION
1. INSPECT AIR FUEL RATIO SENSOR







a. Using an ohmmeter, measure the resistance between the terminals.

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

2. INSPECT OXYGEN SENSOR (for Bank 1 Sensor 2)







a. Using an ohmmeter, measure the resistance between the terminals.

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

3. INSPECT OXYGEN SENSOR (for Bank 2 Sensor 2)







a. Using an ohmmeter, measure the resistance between the terminals.

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