If you cannot afford getting a Snap-On Scanner that has an Oscilloscope Diagnostics feature... The PicoScope offered on Amazon for $139.00 with Free S&H can more than handle a HUGE variation of Electronic Wave Form Analysis and PWM Automotive Diagnostics for observing Hall Effect Sensors and for searching out those Sensors for signs of Sketchy Behavior that make many of us grab a Double Barreled Parts Shotgun and start Blasting Away. It has a small enough footprint as a handy device to keep inside of your laptop carry bag and will serve to reveal a multitude of Serial Data Stream problems with Modules, etc., when other methods used with Basic DMMs will simply never work.
