Oxygen Sensor Inspection


Output Voltage (with Plugs, Rich) Standard: DC 0.8 V or more

Oxygen Sensor Inspection


WARNING

The engine gets extremely hot during normal operation and can cause serious burns. Never touch a hot engine.

Oxygen Sensor Inspection


If the reading is out of the standard (with plugs: 0.8 V or more, without plugs: 0.24 V or less), remove the ECU and check the wiring for continuity between harness connectors.

Special Tool - Hand Tester: 57001-1394

 Oxygen Sensor Inspection


Disconnect the ECU and sensor connectors.

Wiring Continuity Inspection ECU Connector [A] ←→ Oxygen Sensor Connector [B] W/BL lead (ECU terminal 35) [C] BR/BK lead (ECU terminal 13) [D]

If the wiring is good, replace the sensor.

If the reading is within the standard (with plugs: 0.8 V or more, without plugs: 0.24 V or less), check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
