YIQIXIN MN300 Auto Sensor Simulator for Car Oxygen, Oil Pressure, Flow Sensor

Meet the YIQIXIN MN300 Auto Sensor Signal Simulator — the upgraded MN300 in the MNB family, designed to emulate key automotive sensors with precision. This versatile automotive tester lets you simulate signals for oxygen sensors, oil pressure sensors, and flow sensors, enabling thorough ECU testing, sensor calibration, and fault diagnosis in a controlled bench setup. Built for professionals and advanced hobbyists, the MN300 helps you verify wiring integrity, observe ECU responses, and reproduce real-world sensor conditions without needing a live engine.

As the original MN300 Auto Vehicle Sensor Signal Simulator, this model advances the reliability and performance of earlier MNB-3 and MNB-2 units, delivering dependable signal generation for three critical automotive inputs. With included testing clips and connectors, setup is straightforward: connect the clips to the respective sensor circuits and begin simulating a range of operating conditions in minutes. This tool is compact, portable, and purpose-built for precise signal replication in diagnostics and training scenarios.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
