Testing knock sensor with oscilloscope. A faulty sensor will typically produce a weak or erratic signal. 4. The goal is to confirm the sensor produces a signal within expected voltage ranges when engine knock is present and that the ECU properly interprets it. Took a few minutes to play with the oscilloscope and get some patterns on known good and bad sensors. Check the continuity of the knock sensor circuit to the ECM. Use an oscilloscope to verify the knock sensor signal while the engine is running. In this video Rob demonstrates how he uses his Oscilloscope to diagnose and confirm a faulty Knock sensor on a 1996 Toyota Landcruiser. Key facts: 16 hours ago · How to Tell If a Knock Sensor Is Bad?
