ST05 Oxygen Sensor Tester Simulator

  • Availability: In Stock

ST05 Features

  • The sensor signal output is shown in real time on the bar graph, while a 2 digit alphanumeric display shows the sensor output cross count per second.

  • By pressing the ‘Test’ button and performing a snap throttle acceleration of the engine, it tests the response time of the sensor and shows a pass or fail result within seconds.

  • Two buttons allows for simulation of rich or lean conditions to monitor response of the engine control module.

  • Advanced connection detection: The ST05 automatically detects common wire misconnections like ground, heater wires, disconnected test leads, reversed polarity etc. and displays these on the alphanumeric display.

  • It only requires the connection of two probe clips to the oxygen sensor wires, and the selection of the oxygen sensor type.

Simple and flexible to use

  • Sensor can be tested on or off the vehicle

  • Does not require special setups or in depth knowledge to use

  • Provides instant readings and testing capabilities of the output of the sensor

  • Diagnoses “lazy” (slow response) sensors, which may not set DTCs, but cause drivability problems

  • Excellent preventive maintenance tool, to diagnose sensors that need to be replaced before they set DTCs or completely fail

  • Ruggerized electronics make it almost impossible to damage the instrument, even if wrongly connected

  • No software to upgrade.
