The Prologics Sensor Simulator is designed to simulate and actuate an output signal from automotive sensors incorporating frequency, voltage, and test sequences. The Sensor Simulator lets the technician know if the faulty operation is a defective sensor, an issue with the ECM / ECU, or a defect in the wiring. It can simulate ABS sensors, lambda sensors, EGR, CKP, MAP, knock sensors, and more. The tool saves technicians time by eliminating the problem quickly.
