Camshaft actuator testing (VVT) - GM 2.4
HTML-код
- Опубликовано: 11 июл 2024
- GM 2.4L Ecotec engines have a common issue with the VVT system, resulting in a check engine light and trouble codes P0010, P0011, P0013, and/or P0014. In this video, we will show you the step-by-step process of testing the camshaft actuator solenoid and getting to the root cause of the problem.

I could watch this good guy diagnose cars all day long!! Thanks for posting! Super informational!
Hey Fred, thanks man!
~Mike
Great description! Really helps when you show comparison of good and bad solenoid resistance readings. Also, very informative to show that resistance was variable on intake solenoid even when a code wasn't thrown for it. Thanks!
Hey Brian60, thanks for watchin!

Try 7uuu
Thanks for another great video, Mike! All the best to you and the family!
Thanks Dave, to you and yours as well!
~Mike
Some of the best and most useful info found here! Thanks Mike!
Wow, thanks so much Greg!
~Mike
This channel deserves more subscribers Great job on another video
Thanks so much, tell all your friends 😆
~Mike
Nice easy test for these vvt solenoids. Like you said, it could be a more deeper problem, but you need to remove the "slightly intermittent" intake and definitely bad exhaust solenoids to get rid of known problems then proceed if necessary with further diagnostics.
Good one Mike! Hope all's well with you and your family.
Hey Mike,
I agree, and with this vehicle solenoids will fix the issue most of the time
Thanks for watching!

Nice video as always Mike. Makes you worry that sooner or later just about every connector on the car is a potential problem. Yikes !
Hey Rick, yeppers, even more so, if it's on a car...sooner or later it will fail. Nothing is bulletproof on cars anymore.
~Mike
As Always Great update, All the help we need in the field to be fairly intelligent Thanks Mike
Hey Jimmy, thanks for watching! Hope you're doing well!
~Mike
By far Mike, you know your trade. Thanks for the video's.
Thanks so much Gerald!
~Mike
Excellent video Mike! thanks for sharing!
Thanks Keka!!
~Mike
Hola Mike, nice to see you back doing videos. Nice video by the way
Hola my friend! Thanks for watching :)
~Mike
U guys make dope videos!keep up the good work 👍🏽
Appreciate it!!
Great to see you Mike😍
Thanks for sharing this one, I'm also dealing with a P0017 on a 2019 Chevrolet Spark, I switched the Solenoids over but the code remained for the exhaust camshaft solenoid, I also verified the timing mark's based on the info available on RUclips & Google, my suspicion is that it has bad exhaust valve's on one cylinder (sadly I don't have an incylinder pressure transducer to prove that theory) but when the engine is cold it start's right up, but when it's reaches operating temp you have keep the gas paddle pressed half way through to get it started & it stall's immediately when shifted to reverse or drive🕵️🏻♂️
Please shed some light on this one😉
Stay Safe Bro😍
Hello Salman,
I would check for the camshaft phaser to be sticking, if the VVT solenoid is working and moves the Cam phaser and the cam phaser does not move back it can cause this exact issue. Remember P0017 is a cam/crank correlation code and is set if the engine timing is off. A bad exhaust valve bad will only effect one cylinder.
I hope this helps! Thanks for reaching out!
~Ryan Wilsing
@@GoTechTraining Really appreciate your support, I will definitely check that as well👍
Thanks Ryan👍
Thanks!!!!!!!!
Thanks Mike. Had a temp sensor like that years ago on an 86 ish GM. Would read correctly then dropout to 40* F below zero. B U T no codes set ??? TOOK A WHILE ON THAT ONE. Early ECM's were not very smart.
😄😞always great videos but can't watch cause working. Usually save em for l8r but been so busy lately that i now have backlog of unwatched videos.
hahah thanks for trying to fit our vids into your busy schedule!! This is a short one, you can make it work😂
~Mike
Great description and information.
Does anyone know what the voltage from cable harness should be reading?
I have a P0011 code after replacing both solenoid’s. Could my issue be the camshaft position sensors?
Hey James,
The circuit is controlled by the PCM, when commanded on, the PCM will supply power and ground at a variable duty cycle. The P0011 is a performance DTC, also make sure you oil level is full with fresh clean oil.
~Ryan
Keep getting the dreaded P0014 code on my 2010 Equinox 2.4
I replaced the VVT solenoid with a good AC Delco. Still getting the code. Could this be the cam phaser going south? Its up for an oil change soon but, the screens are clean as far as my eyes can see.
After driving for a bit, I have to "2 foot" drive the car so it doesnt die at a stop.
I have replaced the timing chain and guides recently. Everything was good for a bit but, here we are.
Thanks!!
👍👍
Thanks for watching!
My 2013 Equinox 2.4L solenoids were replaced under warranty around 70K miles - with a CEL code stored as you mentioned.
Now at 154K miles the engine vibrates a bit at idle. But no codes stored. Resistance on both is around 11 ohms.
Should I consider solenoid replacement as a preventative measure?
Could it be spark plugs (replaced at 95K) ? Crankshaft and/or camshaft position sensors?
👏🏻👏🏻👏🏻👏🏻
Thanks for watching!
~Mike
Any chance you can tell us what tool this is and where you bought it? It almost looks homemade. Been needing test leads like this! At 5:51
Use the ohm setting on the multi meter for people at home
Yes! Good call!
Thanks for reaching out!
If you replace them and still get a light and some stalling, is that the timing chain.? Or could it just be dirty oil?
Hi
How do i can check the connector of the camshaft position actuator, the connector between the ECM and the camshaft position actuator. Thank you
I have a p0016 on my 2.4L Equinox, feel like it’s the chain and intake sprocket ⚙️, what do you think?
Hello,
That's tough to say, It could definitely be a chain or intake sprocket issue, but there are other failures that can cause this. I have seen shifted camshaft reluctors and stuck VVT solenoids cause this as well. Definitely something that requires testing.
~Ryan
@@GoTechTraining i bought a new VVT solenoid but it didn’t fix it, and don’t know about the reluctor, my car starts but has no power and it misfires, thank you for your feedback tho!
The only way test it would be to check the cam/crank correlation with a scope or manually checking the chain timing. Then figure out why it is off or out of time
If my ohms are at 7 is the vvt on it´s way to brake?
Hi Whitewalker, no not necessarily. Resistance is tricky to judge the health of the solenoid by. If it were .1 or 100,000 I'd say its bad. But something in the single digits or teens is probably still ok
I don't see the links for multi meter or jumpers
Hi Mike,
Thank you so much for pointing that out!
Got it fixed!
Multimeter- amzn.to/3iSAO0F Terminal leads set- amzn.to/3YadsUl
~Ryan Wilsing
@@GoTechTraining Wow multimeter pretty cheap. Works good for the price?
Yeh, it's a good "low cost" meter. It's not a Fluke, but it does the job. We've been using it a ton to try it out.
~Mike
What to do if NO POWER to solenoid through the connector harness? What is the power source? A fuse? The ECM? How can I know which “pin”/ “probe” on the connector is hot vs the one leading to the ECM? Are the ECM wires always or most often striped? Down to my last hurdle after rebuilding this 2004 Corolla 1.8 engine and I can’t figure this out. I’m NOT a tech guy and have a great deal of trouble with all these sensors. ALL new sensors and solenoids so I know their good. Sure would appreciate any help you or anyone out there could give me. I’m m all out of bubble gum lol.

Hey Nick, thanks for watching bud!

Just bake the old one's in the oven at 500 degrees for 7 minutes and it will re-solder itself internally.
Interesting, have you successfully done it? Thanks for watching!
~Mike

Well that's a start 😂
The real problem is that GM has killed off a lot of (all Cobalt) the parts. VVT solenoids are still available, but for how long? Happens to be a part used on a number of platforms. Yay. AFAIK, 2019 last year of production, so I'd think this part will still be available...
But tensioners for the LSJ are long gone.Even the the idler assembly. Forget finding a remanufactured a/c pump with 6-rib pulley.
Ecotec i4 engines are throw-away, despite the money GMP put into this engine. If you want to make this engine your "classic," get spare everything, now.
alligator clips..
