Air-Fuel Ratio (A/F) Sensor

INSPECTION

1. INSPECT HEATER RESISTANCE OF A/F SENSOR




a. Disconnect the sensor connector.
b. Using an ohmmeter, measure the resistance between terminals +B and HT.

Resistance: 1.8 - 3.4 ohms @ 20 °C (68 °F)

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

Torque: 44 Nm (32 ft.lbf)

c. Reconnect the sensor connector.

2. INSPECT OPERATION OF A/F SENSOR
