Oxygen Sensor: Testing and Inspection
INSPECT AIR FUEL RATIO SENSOR
a. Check the resistance. (Bank 1 Sensor 1)
1. Using an ohmmeter, measure the resistance between the terminals.
If the result is not as specified, replace the air fuel ratio sensor.
INSPECT HEATED OXYGEN SENSOR
a. Check the resistance. (Bank 1 Sensor 2)
1. Using an ohmmeter, measure the resistance between the terminals.
If the result is not as specified, replace the heated oxygen sensor.
