Automotive Diagnostic Pulse Sensor for 6 dollars?

Описание к видео Automotive Diagnostic Pulse Sensor for 6 dollars?

See how you can make your own pulse sensor for less than 10 dollars. This sensor works very well at checking intake pulses, exhaust pulses, crankcase pulses, cooling system pulses, injector mechanical operation and noise diagnostics.

In this video, I go through the construction of a simple pulse sensor and demonstrate the tool doing intake pulses, cranking and running, on a good engine and on one with issues. I also show how this tool can work well to check engine noises.
