Pressure Pulse Sensor
It offers a fast and accurate method to diagnose engine problems. Used to verify the mechanical condition of the engine before using a scan tool.
Since 2004 a worldwide use of the so called Pressure Pulse Sensors – PPS in automobile diagnostics started.
In normal operation of internal combustion engines pulse waves of pressure are generated in various systems. All engines produce such waves and their shape is predictable. All engines produce a predictable pattern of these pulses so any change in shape or appearance of asymmetry of these pulses indicates a problem with the engine. PPS detects such faults as burnt valves, bad injectors and other performance problems without major disassembly of the engine. To visualize the waveform of the output signal of PPS, its electrical part is connected to an oscilloscope (motortester; automotive scope). The screen will show in real time the work of valves, cylinders and injectors, and by using synchronization to the first cylinder it can be determined by its performance which cylinders has a problem. The automechanic can therefore quickly and accurately get an idea of the actual condition of the engine. Pressure Pulse Sensor does not need additional external power supply and it can be used with most modern digital storage oscilloscopes (motortester).
