This great looking Buick came in with a very familiar code, P0010, intake camshaft solenoid circuit fault. This is a pretty common issue on GM Ecotec engines, especially the 2.4. I cover some fairly universal methods in troubleshooting this style of solenoid, and use these methods to come to a confident and accurate diagnosis. Methods used…
Using scan data to verify output functionality.
Using functional tests to test solenoids.
Testing power side switched solenoids.
Using resistance tests to identify a failed solenoid.

Nice work. I had the same symptoms on my 2011 Regal. My mechanic found that the intake solenoid was bad, and recommended changing the exhaust too to be on the safe side. Trouble free since both were changed. It's nice to have vids like this to have a good sense of the issue.
Sometimes I wish my electronic devices were more simple. When I reach for the 'off' switch of my alarm clock, I have to find my glasses and turn on a light, then scroll through a menu before I can turn it off. Here, using the Vantage as a multimeter you went though a lot of effort just to do an ohm check, ha ha. This is an interesting video. I wondered whether sometimes it's not the 'action solenoid' but the sensor that tells the PCM what the angle is…. I suppose that could present in a similar way….
Just subbed your channel, regards from Australia.
You have a good troubleshooting mindset. That is key to understanding and being a successful EE. Good work!
Have a bad selenoid on my 2012 Impala. Well the code says it's bad, LOL. The engine light only comes on after a full throttle run and goes out after 4 ignition cycles. I don't have a scope but will definately check the resistance. Sorry can't do a current ramp on it. Great video series!
The contacts in those solenoids are a high failure issue. Sometimes, just moving the connections on those, like when removing the engine cover, will cause the connections in the solenoid to fail. Good thing they are easy to diagnose and replace.
I as well see the same top notch auto technician channel already made. I agree with reweydewy keep the detailed explanation just as some of the other great technicians on youtube! Also whatever video cam you use seems to be top notch in picture and sound quality. Keep up the great vids! Thanks for your time!
Nice job Joe…..
Great info thx
New to the channel.
Where did you get your training?
I've been in the field for 30 years plus.
Well done sir. I hate using probes on component pins like that as readings always seem sketchy. I keep a small assortment of female pins/wires from old connectors/wiring harnesses to use. It speeds things up and adds confidence to those sometimes troublesome ohm checks. Thanks!
you look young man but your a damn good tech from the videos ive seen
I see another amazing auto technician channel in the making! Nice work. You are great at explaining and getting down to the point. Hope all is well. thanks for sharing
Wouldn't it be interesting to see the current ramp of that high resistance solenoid (wink wink). Sure do wonder what that would look like. Great video. Keep em rolling sir
