SKU CH-5B4B-FVC1J

Tests and simulates oxygen sensors for accurate automotive diagnostics and efficient troubleshooting

  • Tests oxygen sensor function to verify emissions performance
  • Simulates sensor signals for diagnostic troubleshooting without engine running
  • Professional automotive hand tool for oxygen sensor analysis
  • New condition ensures reliable operation from first use
  • Listed by manufacturer on 16 October 2018

Diagnostic Tool for Oxygen Sensors

This hand tool tests and simulates oxygen sensor signals to help diagnose fuel-management faults. It connects directly to the sensor wiring so technicians can verify heater circuits and signal output without running the engine. The unit is designed for professional workshop use and was first listed by the manufacturer in 2018.

Suited for Technicians Checking Sensor Health

Mechanics who need to confirm whether an oxygen sensor or its harness is faulty before replacing parts will find this simulator useful. It is not intended for hobbyists who only read generic trouble codes, nor for shops that require live data streaming or graphing capabilities beyond simple signal simulation.

Stand-Alone Tester With No Bundled Software

The product ships as a single handheld unit without cables, adapters or diagnostic software. Users must supply their own back-probe pins or breakout leads to access the sensor connector. Because no firmware updates or PC applications are included, the tool remains limited to the simulation functions built into the hardware.

Questions about this item

Does the Oxygen Sensor Tester Simulator need an external power source or does it draw power from the vehicle's electrical system?

The tool connects to the vehicle's oxygen sensor circuit and uses the vehicle's own electrical system for power during testing.

Can this simulator be used on vehicles manufactured before 2018 without compatibility issues?

The simulator works with standard oxygen sensor signals found on most petrol and diesel engines regardless of the vehicle's model year.

How can I confirm the tester is accurately simulating sensor signals after I connect it?

Observe the voltage output on a multimeter; it should cycle between rich and lean thresholds as the simulator switches modes.
