2014 Chevy Malibu code P2646 Solenoid,Oxygen sensor, Engine variable timing oil control valve issues 

Thanks for the tips. I just did all that. Went with OEM parts. Ended up doing the downstream O2 sensor and changed the spark plugs as well. With a coupon at the dealer, paid $315 for all the parts. No more codes thank God. 🙏 Dealer had quoted me 1200 total for the job, minus the spark plugs.

I got the same dtc P16D0. So I replaced the intake solenoid & the check engine light came back on. After I resetted the engine light & replaced the " engine variable timing control valve" the engine light stayed off. Good video. Pretty easy job.

Perfectly explained in detailed thank you bro for helping me save time and money. 🤝🏽

Sorry I called the $130 part a solenoid it’s a ENGINE VARIABLE TIMING OIL CONTROL VALVE. Oxygen sensor was $80 plus a special tool for $20. The VVt solenoids for intake and exhaust which are called variable timing solenoids costed $40 each. All can be done by you if you have patients and want to save hundreds if not thousands! They all work together in a sense and all gave out at 155,000 miles. Hope this helps and sorry if I confused you

Just fixed mine too had the exact same issue. Thanks brother

I did mine. Was a total shot in the dark. Used Dorman, no longer have the car, but until I got rid of it, never had the code come back after the part was replaced. Was hesitant about Dorman, but at the time the ACDELCO part I think was over 300.

Thanks bro l got the same problem. You are gonna save me some money 💰.

Very helpful Man! How about changing out the accumulator for the ac. I'm having a super hard time trying to take it apart to make the AC function

Cool that's the only thing I haven't replaced, I replaced solenoids and batteries plus dual control module still have engine light

Sound like there was no testing.... jusbpart swapping. Dnt waste your money. Proper diagnosing from someone you trust is key.

Component for oil control is acdelco, duralast, doorman?? I just saw, dorman 😊

Thanxs bro I’m in the same issue you have to

where did you order the timing valve solenoid? herd thats what causes all these codes

Is the code finally gone, buddy? I just change only vvt solenoids and now I will change the VARIABLE DISTRIBUTION ENGINE OIL CONTROL VALVE

Where did you purchase the rocket solenoid valve

What’s the part called

Just fyi Dorman is not a OEM part

Cam-phasers

I changed all 3 and the code won’t go away. Any one have a clue why? Maybe the downstream needs to be changed? I already did the spark plugs 😊

Great video!!! Im having the same problem with my wife's 2015 Malibu. But im only getting the P2646 code and nothing else. Mechanic changed the VVT solenoid. So I'm guessing the intake and exhaust solenoid?

Mines was fine till I pulled over put gas turned it on and drove bout a block and the check engine light came on I opened the gas cap closed it again and it was still on I took it to orallys and it popped up this code
