Camshaft and Crankshaft Position Sensor Waveform Analysis

This video demonstrates how to analyze a camshaft and crankshaft position sensor waveform to identify a faulty sensor, a problem with the variable valve timing, or incorrect timing chain or belt correlation.

Brilliant summary, great explanation for waveforms I've seen before. I keep forgetting to check amplitude of the analog signals.

Thank you Justin. Good job. Have a blessed and safe week.

Iv watched several vids on this but this one is by far the best Thank you 👍

[@johnnyclark4548]

Amazing explanation thanx. I am brand new to this and very exited to learn as much and practice to learn what I need to do when I need to. Thanx again for your good work, I will probable visit here alot 😂😂😂

[@seshachary5580]

awesome explanation and very educative. Thank you Regards

Thanks Justin, Sandy

Nice video

what are the numbers on the X axis? degrees? what degrees, please; crank must repeat every 360? cam every 720? is it volts on the Y axis? *Tks*

[@JustinMillerAutomotive]

The x-axis is initially "time." However, one I bring the "phase rulers" out, I can now place degrees onto the X-axis. The crank signal repeats every 360 degrees and the cam repeats every 720 (because it turns at half the speed). The y-axis is voltage.

[@soptea]

How can drops in cam/crank signals can be detected ,maybe using masks and alarms or a frequency math channel ?Thanks !

[@JustinMillerAutomotive]

That is a great question! I am going to experiment with it and see if I can find a way to do that. Thanks for the great idea!
