I had this problem with customer car. I watched your video and discovered my problem was same as yours. I used a punch and a couple of pry bars to reposition the reluctor wheel. Then I use the welder and tacked it to the cam shift. It worked. Thank you for this video.
I am having the same issue with my 2016 Colorado but I have the 2.5l. It doesn’t have the laser marks on the cam shaft so do you have any information on the reluctor wheel for this motor ? Thanks
Hey Don, is there anywhere I can get the part number for the Exhaust camshaft.. I had the vaccum pump shatter. Crank no start after that, I opened valve cover and fished out pieces.. Reluctor was out so tapped in place.. Now starts but idles rough, POO17 with Engine light on and "Reduced Engine Power"... Changed Oil, Sparks. Havnt done VVT solenoid but I think I may have the reluctor issue... Im I'm New Zealand and they are known as the Holden Equinox here.. Dealer shut down, parts only but waayyyy overpriced and they refuse to give out part numbers. Will get one online but not sure of part number.. Also, is there anything else required apart from the Exhaust camshaft in way of parts? Appreciate any input and assistance please
I have a question for you. I have the same vehicle. I replaced the camshaft after the vacuum pump broke. For some reason, the new cam isn't going in correctly. The A on the exhaust sprocket is turned to the left about 60 degrees from the intake sprocket. Is this normal? I put it all back together and it's still throwing codes. PO1101 and PO0011. When I installed the new chain. I had to grab a wrench and move the exhaust camshaft to the right position to put the chain on. But I feel like this is throwing off the timing. Any advice would be greatly appreciated thank you!
If you aligned the colored links then it should be in time. Some engines will require you to rotate the cam a little to get it timed correctly. Did you install a new chain?
if you take the exhaust camshaft positioning sensor out you can see the camshaft reluctor wheel... tomorrow or Sunday i will attempt to turn the reluctur wheel from the camshaft position location without taking the value cover off by aligning the reluctor wheel tab with the slot that vaccum pump slides into without having to see the laser ech barcode....i use a grabbing tool a magnet stick and some tweezer to clean the piece of the old pump out when i replaced the pump so im not concerned about vaccum pump pieces...i drive my car every day but that rough start and reduced engine speed screen is getting old and i think its messing up my fuel efficiency but other than that i drive my car rather normally
Hey don, I’m trying to see if you help me out. So I’ve replaced the exhaust cam shaft and cam phaser. But I’m still getting p0014 and p0017? Maybe I put in the wrong timing?
@@hectorimperial3817 check your actuator solenoid for an issue. If it’s acting up it can be changing the position of the camshaft actuator and causing these codes.
Hey Don -thank you for the video. We have a 2019 Malibu in the shop now with an intermittent crank/no-start BUT also while the customer is driving it, the car will lose power and she has to pull over and shut it off. It only has the P0014 code and so far the brakes are fine. Oil is full and clean and so far we have not been able to duplicate ANY of her symptoms. Thoughts?
I would swap the cam sensors if they’re the same. See if it changes to the intake side. You could always remove the valve cover and inspect the reluctor position on the camshaft. With it being intermittent, I don’t think this would be your issue. The issue I was seeing would set codes immediately after start up.
Disconnect the cam sensor on the exhaust side and see if it starts. If it does, then you need to inspect the reluctor on the camshaft and the vacuum pump for damage.
Ok so vacuum pump did have damage and it did work. So I replaced the vacuum pump and both sensor and it still only will start with the exhaust side unplugged
I rarely comment or give Kudo's on a RU-vid vid, but this save me and the customer alot of headache. I actually adjusted the realuctor thru the cam sensor hole after finding TDC and changing a broken vacuum pump. thx Mike (Luckiamute Auto Body)
Ive been trying to move the reluctor but its stuck on there. I have it top dead center right now would spinning the motor to align it with the upsidedown reluctor work?
I chose to replace it, but it maybe could have been reused. I didn’t want to take the chance that maybe the reluctor wouldn’t be as tight and could move again.
I've not pulled the cam shaft covers off, but here is a good one. P00014 and P0017. Crank no start. Pull both cam position sensors and car will start and idle. This was after I had replaced both valves. This started on my daughters Malibu after she heard a loud "thunk" from the engine compartment and within 3 miles at interstate speed the motor lost power and died in the fast lane. That is when she also discovered her brake pedal was very hard and more difficult to stop. The vacuum pump locked up and broke off chunks of the housing that surrounds the coupling, and hence knocked the reluctor out of position. I hope I can realign it on the cam. This design is not one of GM's better ideas.
Definitely need to address the reluctor. It likely runs with them disconnected because the ECM is not receiving any info instead of receiving info that says it’s out of time.
@@donshort6651 tapped the reluctor back into alignment with the barcode spot on the cam. Put it all back together and it started first crank. Running well now. Wasn’t the first time for this motor either. I found chunks of vacuum pump from a previous episode. Aluminum
I am have the same problem same codes and car.. I can't find anyone with confidence to fix it. The brake peddle isn't hard now they replaced the brake booster but it isn't running
@@brookebridgewater5219 Is the check engine light on? If yes, can you get someone to pull the codes? If you disconnect both cam position sensors will it start and idle? If so, then you likely have a cam position reluctor ( the thing that spins on the cam and tells the engine where the cam is in its rotation) knocked out of position. Which will require pulling the valve cover to see.
I think I have the same prob... I would of NEVER thought a CRITICAL timing component would be simply press-fit,, and so lose of a clearance that it cane be turned with a few taps from a hammer!! WOW... GM sure Fu'd up this one..
got a 17 1.5 malibu did whole headgasket on it , made sure timing was lined up i put the cam at 12 o clock but when i did my first start engine would just crank and crank no start only start with brake cleaner . everytime i remove valve cover the reluctor moved . i got fuel pressure to low when cranking camshaft postion sensor code and mass air flow out of range . any ideas? i replaced those parts and still nothing same code
Well, I have no way to verify your timing is good. If it starts with brake cleaner then you just not be getting fuel. These are direct injection so there is a low pressure side and high pressure side of the fuel system. Without scanner data I’m not sure where to point you but it does sound like you’re not getting fuel for some reason.
Great video!!! Been trying to find this problem for two days. Vac pump came apart, after fixing, would start, no idle, stall. New sensors, etc, couldn't find it!! thank you.
Did any of the codes came back? My mechanic is currently doing this job, he recommended me to get a new cam, but told him to use the same, he said it might be risky cause check engine light might keep on.
thanks a lot for the info on this video samething happened on this 2020 equinox im working on , the vacuum pump failed and the broken pieces inside the valve cover problably got stucked in between thanks to this video i was able to diagnose the problem correctly
Just did one. Same issue. Very common problem. Its electronically timed, if it moves it will not start! Replace just the cam and the vacuum pump and your good to go. Obviously pull your pan off and clean it out, plus l.o.f. Just reset the timing tensioner and use a small drill bit to hold it. Timing simple. Cam cap torque is 106 inch pounds. Actuator is 15 ft lbs. Plus 90 degrees.
Awesome catch! That was the problem. I used a blunt piece of steel and a hammer to rotate the reluctor ring counterclockwise to get it back into alignment. I used a laser down the camshaft by eye for the realignment and put it back together and the codes cleared and car runs fine now, Thanks. Great find!!
@@donshort6651 I had the crank no start. P00014 and P00017. Pulled both cam sensors and the car would start and run. For what it's worth. Something to try.
You could probably definitely spin it, but I’m not sure you could tell when to stop without removing the valve cover and getting a visual of the camshaft location. If you have a scan tool you could move it some and then watch the cam sensor to see how close it is.
@@Bronze_T_Garage The owner declined further investigation and he may have scrapped it or sold it sorry. I had the valve cover off at one point and the timing was dead on.
