This professional grade oxygen sensor tester uses advanced electronic technology to allow technicians to run response time tests on oxygen sensors.

• Sensor can be tested on or off the vehicle
• Shows a pass or fail result in a matter of seconds
• Equipped with LED bar graph to assist interpret tests
• The cross count result is displayed in real time during tests
• The rich/lean mode simulates lean or rich fuel conditions to monitor the response of the engine control module (ECM)
• Advanced connection detection: automatically detects common wire misconnections like ground, heater wires, disconnected test leads, reversed polarity and more, and displays these on the alphanumeric display
• Provides instant readings and testing capabilities of the output of the sensor
• Test sensor response time. 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
• Rugged electronics make it almost impossible to damage the instrument, even if wrongly connected
• No software to upgrade
• Does not require special setups or in depth knowledge to use

Suitable for:

• 1 to 4 wire oxygen sensors (Heated or unheated)
• Zirconium and Titanium (1 Volt and 5 Volt systems)
• 42 V Ready: can also be used in new generation vehicles with mixed or single 42 Volt systems.

Kit includes:

• EQP-101 Oxygen Sensor Tester
• Two piercing clips with 6 ft. cables
• Protective rubber holster
• Polypropylene carrying case
