This is a very common issue on these Nissan 2.5. Although it can be mechanical engine timing, cam phasers etc. The majority of the time it is a simple solenoid. It would be my suggestion to swap out all three (intake, lock and exhaust) solenoids but the choice is yours. -Enjoy!

    If mine ever throws this code, it'll be the last thing it did before the big engine fire.. geezus!!

    Run from this engine!!

    Its better to be Ginger then Gilligan if you don’t want to have things go sideways. Like you said at the end , poor maintenance, low oil etc causing lots of issues on VVT systems . Any solenoids I have changed are sticky because of metal fillings or gummy and varnishec from old oil.

    By the way I just found you in upstate NY. I don’t mind driving from Toronto

  6. Avataaar/Circle Created with python_avatars Rajesh Shanmugam says:

    Hey thanks for this video. My 2016 rogue also 2.5L gives P0300. It was intermittent when starting. I changed spark plugs and coil pack. Now it’s always throwing P0300. Any idea to fix? Fixid obd scanner said oxygen sensor but multi meter test is okay. It also suggests camshaft position sensor. Feel like I’m shooting in the dark.

  7. Avataaar/Circle Created with python_avatars Luis Acevedo says:

    Hello, I was wondering if you can guide me by finding the location of the transmission preasure sensor if posible I found out that's my issue got a code p0841 and thought I'd just swap the preasure sensor but just can't seem to find it. Thank you for your videos.

    Do i need to run a computer after install or is it plug and play ?

  10. Avataaar/Circle Created with python_avatars Matt Man Productions says:

    Ahh yes, the classic have to take off the rear wheel, plus the back seat in order to get to the solenoids… Must have taken engineers many many long nights thinking of a way to make life harder for everyone

  11. Avataaar/Circle Created with python_avatars Chip Powell says:

    Nice vid, you alerted me to the fact there was more than one, which Alldata and Identifix did not, but I just lifted the vehicle up on a lift, removed the right front tire, remove the piece of plastic out of the way, and you can get to all 3 with no issues.

  32. Avataaar/Circle Created with python_avatars Lee Starr says:

    Eric, my brother owns a 2006 GMC ENVOY DENALI. 5.7l Nice vehicle but the switch burned out twice and keeps bogging down having no power at full throttle from his description. I drove the vehicle and it ran fine. It happens to him all the time. He took it to a mechanic that put a code reader on it and told him it had so many codes that he couldn't work on it. I only have a simple reader myself. My question to you is, have you worked in any of these and what common problems have you found?

  33. Avataaar/Circle Created with python_avatars dipwadz says:

    How many 2.5 engines did Nissan make? I have an '06. It doesn't have that many solenoids. Maybe not even one. Just have an intermittent problem. If it doesn't clear up right away, it might a few blocks to start running right. I'm slowly going through small problems. Bad rear wheel bearing, restored headlights and put clear bra on them, replaced the after market valve cover so no smoke on start up, went through a quart of oil every 400 miles. Hopefully that might clear up the CC below threshold. sometimes that code clears itself. High beams, added fog lights plug and play. Just love the pull your parts places. Fuel tank sensor bad, unfortunately have to replace the fuel pump as a unit.

    "Just a little bit of tension on it". "Tension"? When you are supporting it from below? That is "Pressure", Eric. "Tension" is when you are pulling.
