EG–322 ENGINE – SFI SYSTEM (2JZ–GTE) OXYGEN SENSOR INSPECTION 1. INSPECT OPERATION OF SUB HEATED OXYGEN SENSOR (See circuit inspection in Engine Troubleshooting) 2. INSPECT HEATER RESISTANCE OF SUB HEATED OXYGEN SENSOR (a) Remove the driver's seat. (b) Take out the console box side of the floor carpet. (c) Disconnect the oxygen sensor connector. (d) Using an ohmmeter, measure the resistance between the terminals +B and HT. Resistance: At 20°C (68°F) 11–16 Ω If the resistance is not as specified, replace the sensor. Torque: 20 N·m (200 kgf·cm, 14 ft·lbf) (e) Reconnect the oxygen sensor connector. (f) Reinstall the floor carpet. (g) Reinstall the driver's seat. Ohmmeter +B HT P1483
