The ANSED Diagnostic Solutions HU31035 Automotive Sensor Simulator is designed to simulate and actuate the output signal from automotive sensors such as frequency, voltage, and test sequences. It's especially useful for wiring tests. It can simulate the signal and compare it to the scan tool reading. The Sensor Simulator allows users to eliminate the need to replace sensors that work. Users can simulate most sensors, injectors or actuators, including ABS, lambda, EGR, CKP, knock, and MAP sensors. Simulator functions include simulated resistance, voltage, sine wave, square wave, and simulated temperature coefficient sensors, throttle and pedal sensor sequences, as well as testing mode and simulated mode of oxygen sensors.
