Sheffield Oxygen Sensor Tester and Simulator

Part Number: SHE-ST05
The Sheffield ST05 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.

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.
