Designed to test 1 to 4-wire oxygen sensors, this diagnostic tool evaluates Zirconium and Titanium (1V and 5V) components to provide a pass or fail result in 5 seconds. It includes a rich/lean simulation mode for Zirconium sensors that forces voltage to monitor the response of the engine control module. Additionally, an LED bar graph provides visual signal output while a 2-digit display indicates the sensor's cross count per second.
