Oxygen Sensor: Testing and Inspection
INSPECT HEATED OXYGEN SENSORa. 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 heated oxygen sensor.
b. 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.
