7650Oxygen Sensor Tester and Simulator


This device is designed to test and to simulate 1V Zirconia and 1V/5V Titania type oxygen sensors. The simulation can help user to exam the function of the ECU. Moreover, it can analyze the type of connection wire.


  • Testing 1 ~ 4 wires (with/without heater) oxygen sensor (1V Zirconia, 1V/5V Titania).
  • Connection wires analysis (ground, open, heater, ECU power).
  • Check the ECU response to the sensor by simulating rich/lean signals.
  • LED indication of oxygen sensor signal switching and low power indication.
  • With wire piercing clip (easy for connection), 5 minutes auto power off, proper sealed control panel, high strength housing.
