Air/Fuel Ratio Sensor
AIR-FUEL RATIO (A/F) SENSORINSPECTION
1. INSPECT HEATER RESISTANCE OF A/F SENSOR (Bank 1 Sensor 1)
a. Disconnect the A/F sensor connector.
Resistance:
b. Using an ohmmeter, measure the resistance between terminals +B and HT.
If the resistance is not as specified, replace the sensor.
Torque: 20 N.m (200 kgf.cm, 14 ft.lbf)
c. Reconnect the A/F sensor connector.
2. INSPECT OPERATION OF A/F SENSOR
