P0016 P0017 Chevy 2.4 How to fix “Camshaft Position Correlation code”

All right today, we’re working on a 2011 Chevy Malibu with a 2.4 liter, and this is setting a poo16 and a p0017 Camshaft Position Correlation. camshaft actuator solenoids On this one we actually came in with low engine oil So we started by changing the oil bring it up to level, but that didn’t help at all Continuing to test the camshaft actuator solenoids themselves and they both tested good So I hooked engine vacuum gauge up to it and verified this engine has low vacuum which is a easy way to tell if the vehicles is out of time And as you can see here another valve valve cover pulled off and there’s a lot of extra play in that timing chain And I’ll show you why later on in the video here, but let me show you how I tested this camshaft solenoid First off, I’m gonna pull it out here and check for the debrie in the screen and As you can see let me zoom in a little closer here As you can see those little specks of metal in there, I’m gonna show you where those came from later on the video here and The timing chain Right there, that should have a plastic nylon guide on top of that which is missing So the chains actually been rubbing on that metal Going to bring this cam shaft actuate over to the bench, and we’re gonna bench test it Make sure I’ll make sure the plunger is working properly all I’m gonna do for this is take a power probe which I’ll leave a link in the description to power this up make sure the plunger is moving back and forth properly you’ll be able to hear it click You’ll also be able to see it if you look in there with a flashlight We can also on Check this you can check the resistance of it the specs should be between 8 and 13 ohms, so that’s that expected I don’t want to replace it also you want to clean up any debris that you find on the screen here as you can see we have metals break and That metal debris is actually from that chain riding against that chain guide would know with no nylon bushing on it, so Let me see if I can get the camera down there, so you guys can see a little better Yeah, so right inside there there should be a nylon bushing that’s completely missing So that chains been slapping up and down on that causing small metal fragments get inside the motor and On those very old valve timing actuators So this is what’s causing our P0016 p0017 Camshaft Position Correlation is this engine is actually out of time due to failed timing chain guides Will probably get up new actuate new actuators in it to an engine flushed and do the timing chain with all new guides I’ll also leave a link in the description to other videos on vary valve timing actuator testing but Be sure to hit the thumbs up button and subscribe to my channel for weekly new videos Thanks again flat rate mechanic Thanks for watching my video on camshaft position correlation

  1. I just put a used engine in a customer's car today and I now have both codes. Now I have to prove to the salvage yard that the engine is bad. They have already questioned my ability to install correctly. Now I must drive the car over Monday and show them the problem on the scanner. And I've promised it for delivery to the customer Monday. Thanks for posting and I'm going to be showing this to the yard come Monday. Thanks again.

  2. I am only getting the p0017 code and not p0016 since I am only getting the one code do you think it could be a bad sensor? Plan to tear into it tonight but thought I would bounce that off you.

  3. Having the same codes on a V6 equniox and like you said need the timing chain replaced. What would be the estimated cost for everything?

  4. Everything I needed for this repair.

  5. i have this problems in my pontiac g6 2007
    1.- P0014-00
    Exhaust Camshaft Position (CMP) Sensor Performance Bank

    2.-P0021-00 Intake Camshaft Position (CMP) System Performance Bank 2

    Exhaust Camshaft Position (CMP) Sensor Performance Bank 1

    4.- P0017-00
    Crankshaft Position (CKP) – Exhaust Camshaft Position (CMP)

    5.-P0021-00 Intake Camshaft Position (CMP) System Performance Bank 2

    the oil was changed and cleaned

    the gearbox was changed and a new module was purchased

  6. Could just a p0017 code, be just the solenoid or something to do with the oil level/contaminants?

  7. I have loose chain, just replaced everything from tensioners to chains and sprockets. this car has never thrown a code. tested the actuators etc, never had a code even though you can clearly hear the chain rattle. please watch my video and read the description and let me know what you think

  8. I have the same codes on ma 2009 dodge caliber! I figured id had the same problem, now i can fix it with confidence! Thank You!

  9. Thank you for the video. A lot of the newer cars are very finicky on the type of oil they are given. A P0016 was fixed by the cheapest bullet of the parts cannon.; oil change with the rights specs. Dirty or wrong oil will play tricks with the solenoid. Great video. Thank you.

  10. I just replaced those 2 and my engine light is back on I used the original part I don’t know what to do now 🙁 I need help please what else can it be. the code P0017 help!!!!!!!! Anyone

  11. Stupid fucking Gm engines, the whole purpose of having a chain is that its maintenance free. Great video tho

  12. I changed both sensors on my Saturn Vue 2.4 , cables are also good but I still have this code . What else could be bad .

  13. These type of fast and dirty videos are useless. Many things other than a loose timing chain can cause a P0017. Fix it then post the video.

  14. I see that the intake solenoid is grey, indicating it is for the 2010 LAF Equinox, not the 2011. From the pictures, it looked like it may be a replacement part from another vehicle. You have to use the VIN to go online to determine exactly which engine build you are working on, and the correct intake solenoid. If the grey one is incorrect, putting in the correct one will help.

    The slack timing chain between the 2 phasers seems to indicate a failure of timing chain tension or incorrect valve timing, a problem which would also be indivated if the timing chain lines up with the wrong timing marks on the exhaust phaser(and possibly the intake phaser also). One often overlooked cause of these conditions is a defective or obstructed timing chain tensioner – replacing it with a new one is sometimes quicker than taking the old one off, then taking it apart to be sure there are no broken parts inside of the mechanism, and then resetting the actuator in the de-activated position before re-installing it. They are very easy to break when deactivating them. The torque spec on the chain tensioner upon replacement in the head is 55 ft lbs I think, but check to make sure. Chain tensioner failure, and the resulting retarded valve timing from the timing chain skipping a tooth on the phaser sprocket is a more likely cause of chain guide wear and valve timing issues than a "stretched" timing chain. The metallic and plastic debris caused by the erosion of the top chain guide gets into the chain tensioner, which is run on oil pressure, and can lock it up, thereby causing a "no-tension" situation on the timing chain.

  15. What is the travel on the solenoid supposed to be, MIne test ok but it only moves about 1/4 inch, seems like it should move a whole chamber length?
