So as not to embarrass anyone , I decided to keep it off camera. The solenoid itself tested at 1.3 ohms . I decided not to do a math and basic electrical class on video. But you can do the math from here 😉
I work @ the dealership and see some crazy but interesting case study’s I take a lot from watching your vids to help me become better at diagnosing vehicles Especially the GM vans videos lol horrible designs with their wiring..
the P06DC struck! All I did was change the "solenoid valve" better known as Oil Pump Flow Control Valve part no.12670746. No need to change the PCM / ECM for me. Great video, thank you.
Pleeeaaase everyone, replace the solenoid before the pcm. This guy could be right. It very well could be the pcm. But a solenoid can only fail one of 2 ways. Stuck open or stuck closed. If it fails stuck closed, you will have this exact scenario as the pcm will not be able to control the flow of electricity.
Are you 100% sure that the pcm is toast? I got this error on the same car and replaced the oil pump solenoid behind the heat shield you showed and it fixed the issue. I sure hope you didn't incorrectly diagnose this as the PCM when a new solenoid would have fixed it
Eric O would have removed the metal cover and showed us! Just kidding, I know you guys Are friends. Thanks for the videos, you always shows us things that's i haven't seen before. Thank you!
Yep have one of those sitting in my driveway currently. Gotta go drop it off this weekend. Great video and yeah I dont bother with ohming as there are other ways better ways of testing these as you have shown. They also have variable valve lift on those engines another common failure part. So many parts on these that fail.
would you also recommend replacing the oil pump control solenoid? perhaps it shorts out intermittently and takes out the pcm? the bmws have similar issues where the servo motor for the vvt eccentric shaft draws to much amperage and kills the dme(pcm)
Hey keith dont you fear like lets say an intermittently shorted solenoid coil that took out the driver. I always recommend replacing the actuator the driver is controlling in case like this . do you think its overkill?
Hi! Is the "engine oil pressure control solenoid valve" the same as oil pump pressure solenoid and is it the connector you point to at 2:50? I have a P0523, changed my oil & the oil pressure sensor, yet the pressure still shows around 140 psi. Thank you.
Keith will you be programming the new pcm ? Would be nice to see the difference from the usa gm to uk programming methods. I know they are much the same but be interesting to see how the security side of it is done so as to compare.Regards Joe
Why don’t any car manufacturers make a repairable computer or a out side work around it is not impossible I mean if they are really out to save the environment there are a lot of minerals in a computer
Unbelievable!!!! If you want to buy a GM Vehicle you might as well purchase a Tech 2, MDI, J2534, and a GM Subscription just to be safe 🙄 Any way nice video I'm always learning
Everyone out there don’t go replacing the pcm until you check the oil pressure low oil pressure will make the same as this guy is showing without throwing a oil pressure code my assistant at work watch this video did the same diagnosis did not fix the problem so I took over Hooked up a crappy diagnostics Snap on modis And seeing that the oil pressure switch was low changed it problem solved so be careful don’t go changing your PCM until this is checked
I hate RUclips why should we mechanics help people keep their cars out of the shop oh it’s because you wanna make money on your videos big middle finger for you
I know this Video is 5 years old, but I have to comment. Your diagnostics is incorrect. You had the probe connected on the positive side of the solenoid which will always be at 12V (positive voltage level) and you will not see anything. If you actually saw it drop that would be a major problem. You should of had the scope probe connected to the negative side of the solenoid since you already confirmed that you have positive feed to the solenoid. Second thing is, The solenoid resistance is probably fine. Those circuits are current limiting, hence the fuse.
@@NewLevelAuto yeah, that's my fear... if it's internal to the ECM, GM is commonly known to just fail. IDK how you'd verify if it was done by a spike, like coil.
@@NewLevelAuto it's only rated at 10A at the fuse, so that's a bit too low @1.3ohms. Shouldn't it have popped the fuse then? Or the constant higher amperage but too low to pop the fuse, cook the ECM? You've got me thinking...
This is also the 2nd solenoid... codes were already present and whomever threw the Dorman one in there.... so this wouldn't be the 'cause', is my point

So checking voltage on the blue wire @ the ECM should have seen 0 volts.?
Or at least a voltage drop due to the resistance of the solenoid.?
Only when the driver within the ecm is commanded on . Yes the data display would show ok if the voltage had dropped
Thanks Keith
Just trying to remember if I’ve ever came across that DTC or problem before

Holy crap I diagnosed this exact problem on this exact vehicle 3 yrs ago it's like having deja vu !!
Thank you Keith. Good job. I appreciate your videos. Have a good night.

"Needs a new PCM...it's a GM thing" hahaha hit the nail on the head there, Keith xD

What's the fail state with this crazy setup assuming they deleted the mechanical relief system?
Bursting oil coolers when cold or rod knock when hot!

No problem at all. I will make the video on the programming once they call me in for it.
Is this for an exhaust or intake
Amazing I tell you

That sucks for the owner but we get a good lesson.
Nice. 😉😉
Was expecting to see you confirm the ECM ground inputs before making the call.
All powers and grounds were verified , but who wants to watch me disassemble the connectors with one hand honestly ?
Everyone out there don’t go replacing the pcm until you check the oil pressure low oil pressure will make the same as this guy is showing without throwing a oil pressure code my assistant at work watch this video did the same diagnosis did not fix the problem so I took over Hooked up a crappy diagnostics Snap on modis And seeing that the oil pressure switch was low changed it problem solved so be careful don’t go changing your PCM until this is checked
If the oil pressure switch is low it will not allow the PCM to activate and deactivate this oil pressure control solenoid valve

Why do you use snap on scanners on some cars and a laptop on others.what software are you using on the laptop

That is GM GDS2, it's the OEM scan tool for GM vehicles
Erick Fadeley that is the factory scan tool for the newer GM vehicles. It’s called GDS 2

Wow, so basic. I know I'd 2nd guess myself here. But it's plain to see ECM failure. Explanation couldn't have been simpler.
Just have to verify what killed it right? 😉
