Air-Fuel Ratio (A/F) Sensor
AIR-FUEL RATIO (A/F) SENSORINSPECTION
INSPECT HEATER RESISTANCE OF A/F SENSORS
(Bank 1 sensor 1, Bank 2 Sensor 1)
a. Disconnect the A/F sensor connector.
b. Using an ohmmeter measure the resistance between terminals +B and HT. If the resistance is not as specified, replace the sensor.
Torque: 44 N.m (440 kgf.cm, 31 ft.lbf)
c. Reconnect the A/F sensor connector.
