Tianqifu Universal Auto Circuit Tester Sensor Signal Resistance Simulator: Analog adjustable resistor
This universal auto circuit tester is for the DIY mechanic or automotive student who needs to diagnose sensor issues without swapping parts. While most diagnostic tools focus on reading codes, this simulator creates them, letting you test your vehicle's response to simulated sensor signals.
You can simulate a failing fuel temperature sensor by adjusting the analog resistor, watching how your engine computer reacts to the fake signal. The voltage simulation from 0.1V to 12V covers most automotive sensors, so you can pinpoint whether a problem is in the sensor or the wiring. With six test wires and three extra fine pins, you connect to tight spaces without damaging connectors.
Use it for vehicle maintenance training to teach how different sensors affect performance, or keep it in your garage for quick checks before expensive repairs. It works on 12V systems and handles temperatures from -40 to 60°C, reliable in any workshop condition.
