- i'm attempting to create a little bit different of content with my youtube vs my tt. Im hoping that i can provide you guys with a little bit more info into the way my brain works when diagnosing these hard to figure out issues!! let me know what you think!

Thank you I hate watching reruns on both platforms
I def liked this video! I hope you continue to do more! Just found out my 99 Toyota Celica Gt has a broken distributor they said rotor was not spinning. I'm going to try and fix myself but I am scared lol Luckily my dad is a mechanic well diesel mechanic but I'm sure we got this lol any advice if u know about a timing mark on the front of the engine to make sure we are at tdc?
Oh btw its 2.2 liter
Instead of relying on just the timing mark you can also pull the spark plug closest to the belts and see when it reaches its top point with a long screw driver. On the distributor removal, mark where the rotor points to, then where it points to when removed and installing the new one will be cake with your marks!
@@checkenginechuck what about knowing if it's on the compression stroke or on the exhaust stroke?
Or am I thinking wrong?
Okay disregard everything the distributor isn't broken. We think timing belt because the piece the distributor connects to isn't spinning. So timing belt??? Now I'm worried about holes in pistons lol ugghhhh
Think out loud, trying to pick up how you think through it. Thanks.
That’s the goal with these style videos! Fill in the blanks!!
Love me some power probe
As do I!
It has always floored me that knock sensors are not wrapped in bubble wrap with that said get a fluke meter and throw out the klein and other crap. Fluke meters give faster more accurate readings in a wider range and they seem to never need their batteries replaced, by year three you start thinking they are recharging themselves during use. Its really sad that the dealer oem parts we have used as the biggest failsafe against trash parts is now in the middle of the trash parts problem and I'll be the one to say it really started getting worse after the ford 5.4 3v timing chain BS. Then covid hits and it all went full potato by having no inventory anywhere giving rise to people knowingly selling bad parts and a massive surge in counterfeits.
Dude don’t even get me started on the parts stuff I’ve done a few videos on tt about it over the years
Hey chuck can you do a bit more on load testing. Trying tk learn as well. Somy question would be your sending power thru the harness that ends a pcm. So do you have connector disconnected at pcm and then back probing with a bulb. Im just trying to make sure, because i feel you could fry the pcm. So im trying to learn and want to be clear..
I just got my answer. I should have let the video play through, and you explained with the dart demonstration 😂. Key word everything else disconnected
It’s all good! 😂
Commenting as I watch my own video. I definitely called a knock sensor an 02 at least once 😂
Chuck do you think just a bad batch of sensors. And going forward if you did another gm knock sensor job would you test before putting it back together.
I’ll be bringing a dvom to the dealer when I pick them up 😅 and yes I believe just a bad batch!
All I can tell you is if it got dropped get another most likely the new ones from the dealer got dropped at they'll go back in stock and then resold to the unknowing person that doesn't know Jack squat and since it's electrical the dealership will not take them back
PP4 maxed out at 10k ohms
What’s strange is that the multimeter picked up resistance. I’ll play with it more 😂
There are way too many incompetent people including so-called techs that really do not know what they are dealing with or how it let alone using specifications to do the job😂
Would I find very funny is when someone wants to change the knock sensor when the engine has an actual rod knock these SAME people work on customers vehicles day in and day out I would like a show of hands from those that encountered the same types of shops out there 😂 yet legitimate shops are struggling these are actual Facts
