It primarily simulates the output voltage signal of a 4-Wire O2 Sensor. It helps mechanics and automotive DIY enthusiasts quickly determine if the vehicle&#8217;s ECU and related wiring are functioning correctly, thereby troubleshooting potential faults in the oxygen sensor itself.<\/h2>\n<h3><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0072\/5424\/5449\/files\/item_description_05b88e20-4197-44a7-b336-f258bbb5bd63.webp?v=1771056597\" alt=\"\" title=\"\"><\/h3>\n<h3>Features:<\/h3>\n<p>1. This device simulates oxygen sensor signals.<\/p>\n<p>2. It is specifically designed to simulate four-wire oxygen sensor signals and does not support broadband oxygen sensor signal simulation.<\/p>\n<p>3. The device requires an external 12V-24V power supply for operation.<\/p>\n<p>4. The signal cable from the vehicle&#8217;s oxygen sensor must be disconnected; otherwise, the vehicle&#8217;s oxygen sensor signal and the SO3 simulator signal will interfere with each other.<\/p>\n<p>5. It uses a new single-chip microcomputer as the main control chip, providing excellent interference immunity.<\/p>\n<p>6. An 8-digit LED signal voltage display (average) provides clear and accurate readings.<\/p>\n<p>7. The signal voltage adjustment knob can be adjusted with a flat blade or manually by opening the top cover.<\/p>\n<h3>Measuring the SO3 Simulator Output Signal:<\/h3>\n<p>1. The simulator has eight signal voltage displays.<\/p>\n<p>You can adjust the signal voltage using the rotary knob. The indicator lights show the average signal voltage.<\/p>\n<p>2. Use a vehicle fault code reader to read the oxygen sensor data stream.<\/p>\n<p>3. Use an oscilloscope to view the signal waveform.<\/p>\n<p>4. Use a 5V DC multimeter to measure the signal voltage.<\/p>\n<p>The normal signal voltage is 0-0.9V and fluctuates continuously.<\/p>\n<h3>Specifications:<\/h3>\n<p>Part Name: S03 Oxygen Sensor Signal Simulator<\/p>\n<p>Material: ABS<\/p>\n<p>Color: Black<\/p>\n<p>Size: 70*44*18mm<\/p>\n<p>Power Supply: 12-24V<\/p>\n<p>Adjustable Signal Voltage: 0.2V-0.8V<\/p>\n<p>Purpose: Simulates four-wire oxygen sensor signals<\/p>\n<p>Package Contents:<\/p>\n<p>1 * S03 Oxygen Sensor Signal Simulator<\/p>\n<h3>Note:<\/h3>\n<p>The simulator requires an external power supply (12-24V).<\/p>\n<p>Before connecting the simulator signal cable, you must first disconnect the signal cable from the vehicle&#8217;s lambda sensor.<\/p>\n<p>This device is only suitable for simulating standard four-wire lambda sensor signals.
