Once again Bernie your the best! Your way of dissecting the operation of a the chain and VVT system using the Escope was is really helpful. Bob Powell is right, it's outstanding to watch you use powerful options on the Escope with such ease of instruction. Keep 'em coming, our industry needs all the help it get. Great job!! Thank you!

Awesome stuff Bernie. Quick question. Is it possible that a cam sprocket/phaser that has gotten sticky or full of sludge could display the same sort of waveform or not ?? Or is the ECM looking at a different set of DTC set criteria for VVT specific faults?? I am not asking this to question your diag as I agree with you 100%. Was simply wanting to learn.

Caleb Do to the camshaft trigger moving at start up it would be unlikely. The phasers are pined so they do not make noise at start up, and when oil pressure is applied remove the pin so camshaft timing can be accomplished. Since the camshaft is driven from the crankshaft, if there was a problem, it should move in the opposite direction from the drive. This camshaft is moving in both directions…

Thanks for sharing Bernie, not familiar with the Escope but does that automatically display the duty cyle of the phaser solenoids? Using my Pico I find I have to use maths channel to display the PWM signal on time as a percentage (and draws a line) to notice any variation like in this case with timing aligned but one chain having excessive 'slap', reffering to when you mentioning timing can be…

Robert The Escope does not automatically display the duty cycle of the phaser solenoids.
