Description
The FirstLook Engine Diagnostic Sensor offers a fast and accurate method to diagnose automotive engine problems such as burnt valves, bad injectors and other performance problems without major disassembly of the engine.
When connected to the exhaust or vacuum side of the engine to be tested the FirstLook engine diagnostic sensors enables technicians to quickly display a complete picture of core engine performance on a suitable oscilloscope.
This pressure pulse sensor detects pulse waves through the exhaust or intake side of the engine. Each engine produces a predictable pattern of these pulses which can easily be displayed on your oscilloscope. The pressure pulse wave is detected, measured and Firstlook sends a signal to the oscilloscope. Changes or irregularities in the pressure pulse pattern can be linked to problems within the engine.
Firstlook can also be used to detect fuel system errors on both petrol and diesel systems as well.
The FirstLook sensor requires no external power source and is particularly suitable for use with a PicoScope automotive oscilloscope but can also be used with most other modern lab scopes.
Frequently Asked Questions
What is pressure pulse analysis?
Pressure pulse analysis uses the WPS500X pressure transducer to measure pressure variations in the exhaust or intake system. By analysing the pressure pulses from each cylinder, you can diagnose burnt valves, weak cylinders, bad injectors, and mechanical engine faults without removing components.
What’s included in the First Look kit?
The First Look package includes the PPA adaptor set for connecting the WPS500X to exhaust and intake ports, enabling non-intrusive engine diagnostics through pressure waveform analysis on your PicoScope.
Is training available for PPA?
Yes. We offer a dedicated 1-day pressure pulse analysis training course. PPA techniques are also covered in the FREE 2-day training included with all PicoScope kits and in the oscilloscope masterclass. See guided tests on picoauto.com.
