Nice demo. Using the scanner for intermittent issues also raises the issue of how fast the scanner samples and displays the data. On my Dodge Ram the refresh rate seems pretty slow, compared to the scope.
Hmmm...your experience really speaks to me here...I would also have checked on the codes myself as well.I thought intermittant was the way to go but again, experience with the scope is what I learned here and an understanding of real world effects on the engine/ wiring connections and such...well the light came on very quickly. Thanks for posting this video
Great vid.! I was about to throw a comp. at it. Elec. problems can be a bear! Shows u have to start with th basics, connections, where wires go through panels, wiring harnesses etc.. takes a while, but satisfied customers are the result!
Very nice, you seem quite miffed at the assistant for missing that :). Look forward to part 2! I feel like the fix is much harder than this diagnosis. This, I feel, found little more than the check engine light was telling you, you were just able to validate the problem via actual sensor values, but tracing where something like this, which in my (albeit little) experience is usually from a intermittent short (like a wire with damaged shielding which occasionally touches a ground), but finding those can be near impossible sometimes!
Nice one Dwayne. As always, you make it look so easy and relaxed. Thank you for sharing your knowledge and experience. BTW, i hope things are all good with you. Regards, Joe.
Circuit low and high codes, whether intermittent is specified by the code or not, should always be treated as an electrical problem. In either case, the acceptable range would be from (lets say a 5 volt ref circuit) .3v to 4.7v, anything below that range or above it is what trips the code, the testing method should be the same. A range performance code would be a different story (within acceptable voltage, but not when/what the computer was expecting to see at that time).
Nicely done Dwayne
the mistake is owning that pontiac hiyo.........::::(((((
great as always ...
