GTC ST05 Oxygen Sensor Tester and Simulator
GTC oxygen sensor tester and simulator provides a simple interface for test and diagnostic on any Oxygen Sensor, to quickly determine whether the sensor is defective and needs replacement. It is designed as both a stand-alone tool or as a complement to any scanner during the diagnostic process, and is compatible with all types of Oxygen sensors: Zirconium; Titanium 1 volt; Titanium 5 volt; Wide Band "dual-Cell"; and heated or unheated (1, 2, 3, 4 or 5 wires). This displays the sensor's output signal in real time in a bar graph, allowing to diagnose "Lazy" sensors which may not trigger DTC's but cause drivability problems. It also displays cross counts, can simulate rich and lean conditions, and has a test mode to test the sensor's response time giving a Pass or Fail indication on a large display. Sensors can be tested ON or OFF vehicle. Easy to set-up and use.
