Limp Mode - Nissan Navara YD25 - SCV Replacement

[@PrimalNomad]

My new cylinder head & gasket restoration and repair video is now live! kzbin.info/www/bejne/gIebe3p_bpWfl8U

[@reimondranu7898]

Had a similar issue with my d40 going into limp mode after being idle for a while. Changed the turbo valve solenoid and issue remained with the actuator still having play. Read online that the SCV was related to this specific issue. So i bought the part yesterday and stumbled onto this video at night. Decided to reset the ecu like how you did before changing the scv. To my suprise i had power after being idle for a while. I'll still check the scv to make sure there's no erosion, if there is I'll just replace it. Thank you for making this video. Years later and its still assisting your viewers.

[@PrimalNomad]

That's the biggest Win! I'm so glaf that this is helping still & hopefully keeps these engines alive. Appreciate your comment 🙏

[@DC-ku8vw]

Thank you for this video, I just used it to replace my SCV this morning and my D40 is running like a dream.

That's the best news!! No problem at all :)

[@jericodivina3810]

Thank you very much bro. I’d been having the problem 5 days ago after scv was replaced but then this reset step made it fine. God bless.

[@PrimalNomad]

You are so welcome! I'm really glad that this has helped resolve it finally. Thank you and you also.

[@muzzaball]

Thanks for all the effort you went to, showing us the pointless dropped bolt - maybe you could have used the camera to actually show us a closeup of the SCV before, during and after installation?

[@PrimalNomad]

No problem! Handy to know where these little bolt traps are hey 😉 Thankfully it's not that hard to find the scv, it looks like the one I'm holding on the thumbnail & exactly where the camera shows it it :) Thanks for watching 🙏

[@ramongalvezhumeres6957]

Dear Primal Nomad Thanks for your time and effort to publish you video. I replaced the SCV on my Nissan Navara LE 2012 4x4 & Manual Transmission, given the fact that I was experiencing the same symptoms you described i.e. once starting the engine first time in the morning the motor started fine BUT it stopped once the RPMs. decreased below the 1000 RPM. Same problem for a while but after the motor is at operational temp no more issues though sometimes - on a very random way - it will stop while waiting for the green light at the semaphore. Unfortunately the problem is still there after the replacement. Please note that after following precisely your RESET procedure I couldn't have the CHECK ENGINE LIGHT BLINKING...it has been lit all the time. Then I start the motor and unfortunately still have exactly the same aforementioned symptoms. Please advice. THANKS !

[@CrazoidMetal]

Hi Ramon, I read your comment here and felt I wanted to ask you if you’ve diagnosed/fixed your issue. I have an ‘07 D40 Nav Spanish, with the same problem you describe. I’ve replaced the SCV/cleaned MAF and replaced fuel filter. Car still stalling when cold. I fear it’s a timing chain issue. Any new info on your car? Cheers.

[@PrimalNomad]

I'm so sorry Ramon for a late reply, I never saw this comment until Christopher replied to it! In regards to both of your issues, I'd be very interested to see how your EGR's are, it may be blocked and causing the issue. This can then cause the MAF and BCV to work improperly causing an airflow issue and therefore a similar symptom to your diagnosis. Have you got an EGR plate installed also?

[@CrazoidMetal]

Hi mate, thanks for replying.. I’ll continue the thread for now haha.. EGR is not something I’m far I liar with, however on my car I’m quite sure the issue is worn timing chain/sprockets.. after disconnecting the cam angle sensor the car started and idled normally.. suggesting the sensor picks up the issue with the chain and cuts the motor out.. it is more of an electronic ‘cutout’ rather than a stall issue. I’ve since taken steps to buy a double row/duplex chain upgrade kit. Very expensive, but gotta do it.

[@cordellej]

thats awesome bro i recently changed my scv and the upper chain tensioner as that was bad . the timing is spot on. i used a diagnosis tool reset the scv and now the vehicle is not starting at all ( advice came from a haynes manual) im gonna try your method tomorrow to see what that does mines a R51 pathfinder by the way 2006

[@J.J.BAILEY]

Would be good to hear how you get on as I’m contemplating doing the same on my 07 pathfinder as I’ve been quoted over 400 from a garage to do the work.

[@PrimalNomad]

I hope you both managed to get it all sorted in the end? Did the fuel pump reset help?

[@PrimalNomad]

Hey! Sorry for the late reply, how did it go?

[@aston_rug1949]

Hi mate .. I have my nissan pathfinder, when climbing hill go slow and i have clean the throttle, still the same

[@PrimalNomad]

Could be worthwhile cleaning your MAF sensor, EGR or BCV, they could all be culprits. But likely to be an airflow issue, maybe vac lines would be worth following to the air box and check for any leaks or splits

[@conmanumber1]

Hi from Oamaru Sth island New Zealand Question. Any other possible causes to this misery? A horrid white Hazy comes out of my 2012 Nissan Navara D40 St-X Diesel Spanish built then engine has rough lumpy idle then cuts out after 2 minutes or accelerated. E.g.r valve and cooler is fine. I possibly have coolant leak but there's no water in my sump oil or oil in radiator coolant. I'm not sure if e.g r valve failure can lead to same symptoms or ths. Do you think s.c.v would cause any issues to symptoms?. Cheers Carl

[@PrimalNomad]

Hi Carl! Sorry for the late reply, KZbin hid this from me for some reason 🤔. I'd suggest that the limp mode might also be related to the MaF sensor or BCV but potentially an injector issue also. Have you tried doing an ECU reset & fuel pump reset to see if you get any improvement, even temporarily? If not maybe I can arrange a chat with you to further diagnose. Liam

[@oratileknowledge4409]

Hello sir, we did the whole process of resetting the pump and ecu but the still the car doesn't start,I don't know what's causing it not to start,maybe you could enlighten with other causes that causing the car not to start 🙏

[@tekarniebessell3335]

Do I have to bleed the diesel injectors when I replace scv? I've heard of diesels reving up and not shutting off So that's my only issue. Do I have to unplug something and bleed injectors once I've replaced scv. And do i need to reset fuelpump, and ecu. I have a tune so will that effect it.

[@PrimalNomad]

No you shouldn't have to at all :) - Just the fuel pump reset so it learns the new valves tolerances. Thanks for watching

[@Jay-Aesum]

What if i replace the suction control valve then starting it and driving away ? what would happen ?

[@PrimalNomad]

Nothing, it will just run on the old setting adjusted to your old valve. You can do the ecu reset now if you want and it will learn the new valve

[@maryellabrown5350]

I changed the part put when doing the last bit my engine lights never flashed at all what does that mean

Brother , my navara automatic ,thai, 2010 edition ,having the problem of not getting power after 2500 rpm and gives a shake when i turn off the engine ,can SCV be the reason? CUZ I changwd the pruge control, turbi control solenoid last week still same

[@atsupatsu2633]

Hello, your problem seems exactly like the mine one. I have used my Navara automatic since 2006 like that, avoiding any acceleration more than 3000 rpm. Btw, I visited 5 different Nissan dealers during the warranty period, nobody was able to solve the problem. Suction control valve had been changed also.

[@sssperera]

Try this which I do for my navara d40 for fuel problems. Buy a liqui moly diesel purge remove the fuel line into the pump & return line from the fuel filter. Take a glass jar and fill liqui moly and put both removed fuel lines into the jar. Start the cab & continue it with different rpm levels. It will cleanup everything in rail and pump. Problem will resolve.

[@ElvisSaavedra-y8r]

I did not Understand how you stepped the acelerator in order not to scan the system

[@PrimalNomad]

Sorry for the late reply, To carry out the reset, follow these simple steps: Turn ingnition on so all dash lights come on. Wait 3 seconds PUMP accelerator pedal 5 times within 5 seconds.... Take foot off the accelerator after last pump and wait 7 seconds... After 7 seconds press and hold down accelerator pedal for 10 seconds... Atfer 10 seconds the Engine Managment Light will start to flash, at this point remove foot from accelerator. the Nav is now in diag mode, so let the EML flash for a bit. the press and hold the acclerator pedel down for more than 10 seconds..this will then reset ECU and fuel pump etc......and put them into learning mode.

Sounds exactly like mine! Definitely worth changing the scv 👍

[@andyvandewal4924]

my Navara automatic transmission starts fine and drives ok, but a couple of times limp mode yesterday. today starts fine but when taking off still is has no power until I have some speed. no fault codes in ecu. could it be the SCV? thank you very much!!

[@PrimalNomad]

Hey Andy! That definitely sounds like a dodgy SCV, it's also worth checking over your vacuum hoses from the Boost solenoid (on the side of the air box on my manual d40) and the MAF sensor on the airbox also, mine was limping from the moment I turned the ignition once and it was the MAF sensor plug wasn't clipped in fully. Limp Mode is a very common symptom for the SCV though and it's a part worth changing every 5 years or so in my opinion.

[@andyvandewal4924]

@@PrimalNomad thank you very much for responding! Ive already checked the hoses and maf sensor. Ordered an SCV and I hope it’s ok when installed. I’ll keep you updated!

Hi Lewis! Sorry to hear you're having issues. I'd definitely recommend changing this valve if there's an issue with fueling (sounds like it) it could be that it's in a perpetual Limp and therefore can't start!

My np300 d22 yd25 engine will get a little bit stuck on rev 900-1100 and rev slow and after that it will do perfectly... When driving when going over a bump and the rev goes below 1 especially on gear 2&3 it will rattle also when when loaded on a small hill it will rev down and will turn off forcing me to use 4wheel drive high what could be the cause and how can I resolve it? Thank

[@PrimalNomad]

It could potentially be a faulty SCV if it's in Limp Mode, mine used to do a smiliar thing after booting it a bit, if not maybe a boost control solenoid or transfer case switch if its forcing 4wd high? I'm not too familiar with the np300 albeit!

[@mrbee6339]

Hi do you have to pump the acceleration pedal to reset or can you just drive as normal after letting the 4x4 warm up first?

Hey! Only to reset the fuelpump you should pump the pedal. Do it after changing the scv for sure! If not normal starting procedure :)

@@PrimalNomad okay cheers also I have a hissing noise on acceleration been told its a boost leak although doesn't seem to lose power.. could that be right?

@@mrbee6339 definitely worth chekcing out the vac lines and the turbo actuator! The lines go from the bcv to the various parts I have another video on that too. The lines can split and cause a boost leak although I'd think you'd feel the lack of power at points on boost.
